Thread: Can I call a function inside condition of if statement?

Code:

#include <iostream>
#include <string>


using namespace std;


string username;
string password;


void passwordcheck();
void passwordwrong();
void passwordcorrect();


void passwordcorrect()
{
    cout << "You may enter. \n";
    
}


void passwordwrong()
{
    cout << "Access denied. \n";
    
}  


void passwordcheck()
{


    
    
        if   ( (username == "a" && password == "a")
            || (username == "b" && password == "b")
            || (username == "c" && password == "c"))
    
         {
             passwordcorrect();
            
        


         }
             
            


        else 
         {
               passwordwrong();
             
         }
    




    
}












int main()
{ 
    for ( int attempt = 0 ; attempt < 3;  attempt++ )
     {


     cout << "Username: ";
     getline (cin, username );
     cout<< endl;


     cout << "Password: ";
     getline (cin, password);
     cout << endl;
    


     passwordcheck();


 // can you do this?


         if (passwordcorrect())
         {     
                        cout << "You may enter. \n";
            break;
         }
     
      
     }
    
    


    


        
    system("pause");
    return 0;
     
}

I tried like this but I get error. Can you actually call function in an if statement's condition?

Can I call a function inside condition of if statement?

Yes, but the function will probably need to return a value that can be evaluated as true or false.

Also in future please ask your question in the body of the post, not the title and not inside the code tags.

Thanks Jim.
