My teacher wanted me to make a program based on An Employee which includes -
His Name
His Id
His Sallary
and we needed to make this using - Structures & Functions & Array as we are not that good in C++ so we just make simple programs . the code of the program i made is below , [ http://pastebin.com/9UFFJseN ]
#include<iostream.h>
#include<conio.h>
#include<dos.h>
#include<process.h>
#include<stdio.h>
struct employee
{
char empname[40];
int empid,empsalary;
}; employee e1;
void add_record(void);
void display_record(void);
void search_record(void);
void welcome();
void exito();
void main()
{
clrscr();
int choice,id;
cout<<"Welcome to Employee Info Menu by Rohit Jalan \n\n\n";
cout<<"1 -> Add Record\n";
cout<<"2 -> Display Record\n";
cout<<"3 -> Search Record\n";
cout<<"4 -> Exit";
cout<<"\n\t\t --> ";
cin>>choice;
switch(choice)
{
case 1: add_record();break;
case 2: display_record();break;
case 3: search_record();break;
case 4: exito();
}
getch();
}
void add_record()
{
clrscr();
cout<<"You have pressed 1\n\n\n";
cout<<"Please enter employee name : ";
gets(e1.empname);
cout<<"Please enter the employee id : ";
cin>>e1.empid;
cout<<"Please enter the employee salary : ";
cin>>e1.empsalary;
cout<<" \n \n \n \n";
main();
}
void display_record()
{clrscr();
cout<<"\nEmployee Name is : ";
puts(e1.empname);
cout<<"\nEmployee ID is : ";
cout<<e1.empid;
cout<<"\nEmployee salary is : ";
cout<<e1.empsalary;
getch();

}
void search_record()
{int id;
clrscr();
cout<<"Please enter the id of the employee\n: ";
cin>>id;
if(id==e1.empid)
{
display_record();
}
else cout<<"\nRecord not found...";
getch();
main();
}
void exito()
{clrscr();
cout<<"\n\n\n\n\t\t\t Thank you. ";
cout<<"\n\n\n\n\n\n\t\t\t Program by \n\n\n";

delay(100);
exit(0);
}
And now my teacher is asking me what if she wishes to enter more then 1 record of data and display more then 1 , or you can say she wants to decide that how much she wants to enter and display , as i am unable to solve her problem i request you all guys to help me in a simple and easy manner as i`m newbie out here . Please don't delay in answer i have a practical examination on 27th Feb 2015 . if you are unable to see my coding -

Thanks In Advance .
In order to perform actions more than once, you need a loop.
unsigned int Display_Menu(void)
{
unsigned int selection = 0;
while (selection != 4)
{
static const char menu_text[] =
"\n"
"Welcome to Employee Info Menu by Rohit Jalan \n\n\n"
"1 -> Add Record\n"
"2 -> Display Record\n"
"3 -> Search Record\n"
"4 -> Exit\n"
"\t\t --> ";
cout.write(menu_text, sizeof(menu_text) - 1);
cin >> selection;
if ((selection >= 1) && (selection <= 4))
{
break;
}
cout << "\nInvalid selection, try again.\n";
}
return selection;
}
The above function displays a menu and if the User enters an invalid choice, it will print the menu again. After a valid choice is received, the function returns to the caller.
This is an example of doing something more than once.
So if your instructor wants to perform more than one action, how would you do it?
Edit 1:
In general a Menu consists of two pieces: 1) Displaying the selections and 2) Processing the choices. The above code handles the displaying of the selections.
// Forward declarations
void Add_Record(void);
void Display_Record(void);
void Search_Record(void);
void Process_Choices(void)
{
unsigned int choice = 0;
do
{
choice = Display_Menu();
switch (choice)
{
case 1: Add_Record(); break;
case 2: Display_Record(); break;
case 3: Search_Record(); break;
}
} while (choice != 4);
}
The above function displays the menu, calls functions according to the User's selection and repeats. It ends when the User enters the number 4.
Again, notice the loop construct that is used for performing actions more than once.

It is a program that takes information then saves it to a marklist file and then outputs it again and then the output is not properly aligned to the rows above. How can I align the output program correctly? Once there was a 2 digit number, the alignment is being disoriented.Notice that the output is not properly aligned

I am trying to make a really simple text menu of sorts using switch statements for a class assignment. The issue is when calling the various functions I've made in the different cases of the switch statement, the never seem to end.
Considering the same issue seems to be happening to all the functions in my switch statement I think it might have something to do with the switch statement itself and not the individual functions although I honestly don't know at this point.
Disclaimer: I know I have tons of other issues with my code, but im just trying to pick a big one for simplicity. I would appreciate advice on other parts of my code aswell. (Also its not done yet as you can probably see by the unfinished cases)
Example output:
==================
1. Admission's Office
2. Student
3. End Program
==================
Enter your choice: 1
Enter the password: 123
******************
1. Add a new student
2. Add new students from a file
3. Drop a student
4. View one students info
5. View all students info
******************
Enter your choice: 1
Enter the first name: First Name
Enter the last name: Last Name
Enter the gender: m
Enter the first name: It should only ask me once
Enter the last name: Why is this looping?
Enter the gender: ????
Enter the first name:
Enter the last name: ???????
Enter the gender: a
Enter the first name: ^C
Code
//main.cpp
int main() {
Student stuAr[SIZE];
int choice, password, userInput;
int numStu = 0;
bool valid;
do {
userMenu();
cin>>choice;
cout<<endl;
switch(choice){
case 1:
cout<<"Enter the password: ";
cin>>password;
cout<<endl;
valid = checkPass(password);
if (valid) {
adminMenu();
cin>>choice;
cout<<endl;
do {
switch(choice) {

break;
case 5:
viewAllStu(stuAr, numStu);
break;
}
}while(choice != 6);
}
else {
cout<<"The password is wrong."<<endl;
}
break;
case 2:
break;
}
}while(choice != 3);
return 0;
//still main.cpp
//addStu function for case 1 of the nested switch statement
void addStu(Student stuAr[], int& numStu) {
cin.ignore();
cout<<"Enter the first name: ";
stuAr[numStu].setFN();
cout<<endl;
//cin.ignore();
cout<<"Enter the last name: ";
stuAr[numStu].setLN();
cout<<endl;
cout<<"Enter the gender: ";
stuAr[numStu].setGender();
cout<<endl;
numStu++;
return;
}
You are never rereading choice within your inner loop.
if (valid) {
adminMenu();
cin>>choice; // only done once, therefore do loop never terminates
cout<<endl;
do {
switch(choice) {
case 1:
addStu(stuAr, numStu);
break;
// ...
}
// after switch-case, add:
cin >> choice;
cout << endl;
You never change choice in the inner do..while loop, and therefore the condition choice != 6 will always be true, unless you enter it in the first time.
The code I wrote seems to work when i write data in the file but when i look into the record.dat file after writing into it, it shows nothing. The segment with "Main Menu" gets repeated from the switch() every time i try to read from the file. I had to write the open commands with the access modes separately inside each case otherwise it wouldn't even open the file.

Each time you open a file for writing under a case statement, you also need to close the file. When the file is closed, the double buffered values are then written to the physical file.
Under case 1, add a file close after the while statement:
} while(opt=='y'||opt=='Y');
rfile.close();
Make similar updates to case 2 and 3, and both case 1 and 2 will now work. Case 3 has additional issues. For example, when opening the file to modify, you will want to use the "app" bit mask so you do not delete existing contents. See the following for more information:

In find_name() function:
while(inventory>>rec.prodtype>>rec.menutype>>rec.prodnum
>>rec.prodname>>rec.prodprice>>rec.quantity)
You dont declare what inventory is in this function. Did you mean to open a file in a variable called inventory like you did in the other functions?
The reason the compiler is giving weird errors is you declared a type called inventory and so not seeing a local variable called inventory it assumes you're using the type which makes no sense in the context of the above line and the compiler gets confused and gives a fairly obscure error.
Why is the following code not giving results and how to get results?
Whenever I run the code, it first asks for the names of the players of two teams playing the match, then it shows the menu from which if we select any one of the option it again asks for the batsman name which is not according to the program designed. My research on the code and the problem is that I think buffer memory is full but I don't know how to free it, any help would be beneficial. Thank you

This is very wrong:
for(int j=0;j++;j<12)
It should be:
for(int j=0; j < 11; j++)
You are also missing a break in your case 4 statement for the options:
case 4: {cout<<"Enter number of wickets to be updated:";
cin >>upwicket;
cout<<endl;
wicketstaken[k]+=upwicket;
break;
}
default:cout<<"wroung choice";
Without the break you will see also the output wrong choice when the user selects option 4.
