Thread: when i run the program windows says "7-pass.exe has stopped working".

i named the program 7-pass.cpp.
Modify your password program from before to put all of the password checking logic into a
separate function, apart from the rest of the program.

Code:

#include<iostream>
#include<string>
using namespace std;
string passcheck(string check)
{
    string pass;
    pass=("abcd");
    if(pass==check)
        {
            cout<<"access granted!";
        }
    else
        {
            cout<<"acess denied!";
        }
}
int main()
{
    string password;
    cout<<"enter your password:\n";
    cin>>password;
    cout<<passcheck(password);
}

the program runs and displays the results correctly but everytime it shows 7-pass.exe has stopped working.is something wrong?

What compiler are you using, again ?

Your function 'passcheck' ought to return a value but it does NOT.

But you should be getting a warning as shown in post#3.

test.cpp:16:1: warning: no return statement in function returning non-void [-Wreturn-type]

If you're not getting a similar warning then you need to see about increasing your compiler warning level so that it can better help you find the problems.

If you are getting any warnings, you should always fix the warnings. In most cases warnings should be treated as errors and always fixed.
