Why to write "return 0 ;" when function is (int main)

Answer 1

deep jani, if you are a programmer then you should have to know that every function has its return type like int,float or void etc.. when main method is called with integer return type then will have to write return 0; because 0 is a integer and it return 0.

Answer 2

if its a char then can we write
return a;

Answer 3

main method is called either int main() or void main()
and mostly void main is not used in c++ .

Answer 4

char func ()
{return a;}

is it legal

Answer 5

you can use return int; or return(int);
but in char you can not use as return char;
follow this code to know more
#include <iostream>
using namespace std;

char printSomething() {
return('a');
}

int main() {
char c;
c=printSomething();
cout<<c;
return 0;
}
this code will generate output char (a). by returning it from the function.

Answer 6

yes return a; in that program because a holds the value of 'g'
and this will produce output 'g'.

//what will happen if I write return 0
}

char c;
c=printSomething();
cout << c;
return 0;
}
