having issues comparing strings - c++

Question

For some reason it skips over the first input an goes straight to the second one.
#include<iostream>
#include<string>
using namespace std;
int stringWork()
{
const int LENGTH = 40;
char firstString[LENGTH], secondString[LENGTH];
cout << "Enter First String: ";
//it skips over this following line
cin.getline(firstString, LENGTH);
cout << "Enter Another String: ";
cin.getline(secondString, LENGTH);
if (strcmp(firstString, secondString) == 0)
cout << "You entered Same string two times\n";
else
cout << "The two strings you entered are not the same\n";
system("pause");
return 0;
}
int main()
{
stringWork();
return 0;
}
it only allows input for one string

Answer 1

This piece of code works on my machine just fine. However, please do change #include <string> to #include <string.h> or #include <cstring>, and add #include <stdlib.h> or #include <cstdlib>.

Answer 2

Fix the code like this:
#include <iostream>
#include <string>
void stringWork()
{
const int LENGTH = 40;
char firstString[LENGTH], secondString[LENGTH];
std::cout << "Enter First String: " << std::flush;
std::cin.getline(firstString, LENGTH);
std::cout << "Enter Another String: " << std::flush;
std::cin.getline(secondString, LENGTH);
if (strcmp(firstString, secondString) == 0) {
std::cout << "You entered Same string two times." << std::endl;
} else {
std::cout << "The two strings you entered are not the same." << std::endl;
}
}
int main()
{
stringWork();
return 0;
}
Some notes about my version of your code:
Please don't use using namespace std.
Use std::flush to flush the characters in the output stream. This is necessary because usually the characters are only flushed with std::endl or in some implementations if you add a newline character.
Avoid mixing C and C++ code as you did. Use the std::getline method to read a line directly into a std::string. Shown in the next example.
Please care about your code style, especially if you post it in the public.
A even better implementation would avoid any C code and use just C++:
#include <iostream>
#include <string>
void stringWork()
{
std::cout << "Enter First String: " << std::flush;
std::string firstString;
std::getline(std::cin, firstString);
std::cout << "Enter Another String: " << std::flush;
std::string secondString;
std::getline(std::cin, secondString);
if (firstString == secondString) {
std::cout << "You entered Same string two times." << std::endl;
} else {
std::cout << "The two strings you entered are not the same." << std::endl;
}
}
