The boost function rowclicked refers to a pointer to a function that returns a void and takes an integer as a parameter. I am trying to pass an IF condition for this pointer, basically saying if rowclicked gets activated,I wish to assign some values
boost::function<void(int)> rowClicked;
userClass->getTable()- >rowClicked=boost::bind(&UserController::onCellTableclicked,this);
this is the If condition
if(userClass->getTable()->rowClicked)
{
std::cout<<"Row Clicked";
m=i;n=j;
}
}
What changes do I make so as to pass an IF condition for a boost function that has been binded already in the class constructor..
userClass->getTable()->rowClicked=boost::bind(&UserController::onCellTableclicked,this);

I'm trying to make a "Flames" program and my problem is after the user enters his/her name accompanied with the partners name and gets the result i want to ask the user if they want to enter another name without using loop .
I've tried using goto but then errors occur where the user cant enter the initial name.

You can use while loop like below:
using namespace std;
int main()
{
while(true){
system("cls");

cin.ignore();
getline(cin,fname1);
cout<<"Enter partners name: ";
getline(cin,fname2);
cout<<endl;
for(i=0;i<=fname1.length();i++ )
{
fname1[i]=toupper(fname1[i]);
}
for(i=0;i<=fname2.length();i++)
{
fname2[i]=toupper(fname2[i]);
}
x=fname1.length();
y=fname2.length();
//============check for spaces=========
for(i=0;i<x;i++)
{
if(fname1[i]==' ')

name1spc++;
}

name2spc++;

I am working out a way to create 10 bunnies at the start of the code, by creating a variable num. The for loop runs 10 times, everytime increasing num by +1. Each time creating a new instance of the class bunnies and assigning the value of num to the name of that instance.
The void create() is not giving me any problems, its when I try to do void printCreate() that I get this error. It just comes up with "Severity Code Description Project File Line Suppression State
Error C3867 'bunny::printCreate': non-standard syntax; use '&' to create a pointer to member Bunnies c:\users\bob\source\repos\bunnies\bunnies\bunnies.cpp 145
". I have looked this up, but I can't understand how to fix this error. Could someone please tell me how to fix this in simple terms?
Replace num.printCreate; in your loop by num.printCreate();.
All functions have be declared public in my .header file
this is my code:
void menu
{
int option = 0;
//cout menu here//
//getting user input to enter their option of menu
cin>>option;
menuChoice(option);
}
void menuChoice(int option)
{
int kiv = 0;
const int size = 50;
while(option) //option just an int to get input from a menu
{
switch(option)
{
case 1: {
while(kiv<size)
{
//codes here to read user inputs then entry increment
++kiv;
}
//cout<<kiv<<endl; // doesn't work here too , it displays nothing
}break;
case2:{
cout<<kiv<<endl; // displays 0
}break;
}
}
}
i have declared the kiv on top , then increment it in the while loop , however the value stays in the while(option) loop so when i go to case 2 , it suppose to print out the incremented value , but it display 0 , am i going in the correct direction?
This may be the one you looking for
int kiv = 0;
const int size = 50;
void menuChoice(int option);
void getOption()
{
int option = 0;
cin >> option;
menuChoice(option);
}
void menuChoice(int option)
{
switch (option) {
case 1:
while (kiv < size) {
//codes here to read user inputs then entry increment
++kiv;
}
//cout<<kiv<<endl; // doesn't work here too , it displays nothing
break;
case 2:
cout << kiv << endl; // displays 0
break;
}
getOption();
}
void menu()
{
//cout menu here//
//getting user input to enter their option of menu
getOption();
}
int main(int argc, char **argv)
{
menu();
return 0;
}
It's not entirely clear from your example, but I am guessing that each time you process a menuChoice you enter that function, and as a result you re-initialised kiv back to 0 each time.
If that is the case, you probably need to change the type of kiv to
static int kiv = 0;
This will cause kiv to retain its value between invocations.
I am trying to sort an array of pointers, which are pointing to a character array of names. I can get the program to sort the first two names but not the rest. Also the names are part of a structure.

Class* ptrs[MAX];

bool Continue=false;

ptrs[i]=&classes[i];
}

}
switch (choice) {
case 1:
add(ptrs,num_classes);
num_classes++;
break;
case 2:
edit(ptrs,num_classes);
cin.ignore();
break;
case 3:
sort(ptrs,num_classes);
cin.ignore();
cout<<"Enter the name of the class to display: ";
cin.getline(class_selection, MAX);
for (int j =0; j<MAX; j++) {
class_ptr[j]=&class_selection[j];
}
Bin_search(ptrs,num_classes,class_ptr);
break;
case 4:

This code is comparing i-th character of corresponding titles, not the whole titles:
if (ptrs[i]->title[i]>ptrs[i+1]->title[i]) {
// ^^^ ^^^
Possible ways to solve:
Change this
char title[MAX];
to
std::string title;
And after that you'll be able to write
if (ptrs[i]->title > ptrs[i+1]->title) {
Only if you can't use std::string for some reason, use strcmp:
if (strcmp(ptrs[i]->title, ptrs[i+1]->title) > 0) {
my input file:
QT, Quan Tri, 4
KT, Kinh Te, 4
DT, Dien Tu, 5
MT, My Thuat, 4.5
NN, Ngoai Ngu, 4
my method:
void ReadFileDT(fstream &file)
{
char c;
CarneerDT dt;
int i=0;
int t=0;// position attributes
int k=0;
char number[10];
while(!file.eof())
{
c=file.get(); //get a letter in the file
//end of line processing
if(c=='\n')
{
break;
}
if(c!=',')
{
switch(t)
{
case 0: dt.id[i++]=c;break;
case 1: number[k++]=c;break;
case 2: number[k]=c;number[k+1]='\0';dt.year=atof(number);t++;break;
}
}
else
{
switch(t)
{
case 0:dt.id[i]='\0';break;
case 1:number[k]='\0';strcpy(dt.name,number); k=0;break;
}
t++;
}
}
cout<<endl;
XuatDT(dt);
}
void ReadAllDT(char *tenfile)
{
char c;
fstream file;
file.open("NganhDT.txt",ios::in);
if(file.fail())
{
cout<<"File Error!";
exit(1);
}
while(!file.eof())
{
ReadFileDT(file);
}
file.close();
}
it show "Run-Time Check Failure #2 - Stack around the variable 'number' was corrupted." and year always equal to 0.00000000000. Was I wrong in line:"case 2: number[k]=c;number[k+1]='\0';dt.year=atof(number);t++;break;"?
This code is structured slightly wrong
if(c!=',')
{
switch(t)
{
case 0: dt.id[i++]=c;break;
case 1: number[k++]=c;break;
case 2: number[k]=c;number[k+1]='\0';dt.year=atof(number);t++;break;
}
}
else
{
switch(t)
{
case 0:dt.id[i]='\0';break;
case 1:number[k]='\0';strcpy(dt.name,number); k=0;break;
}
t++;
}
it should be
if(c!=',')
{
switch(t)
{
case 0: dt.id[i++]=c;break;
case 1: number[k++]=c;break;
case 2: number[k++]=c;break;
}
}
else
{
switch(t)
{
case 0:dt.id[i]='\0';break;
case 1:number[k]='\0';strcpy(dt.name,number); k=0;break;
case 2: number[k]='\0';dt.year=atof(number); k=0;break;
}
t++;
}
But I must admit I don't immediately see why your code would lead to stack corruption.
