Question

It’s a very simple program. I have a function defined on the top and in the loop I am calling the function print.

But I am getting the following errors:

prog.cpp:5: error: variable or field ‘print’ declared void
prog.cpp:5: error: ‘a’ was not declared in this scope
prog.cpp: In function ‘int main()’:
prog.cpp:11: error: ‘print’ was not declared in this scope

Here it is:

#include <iostream>    
using namespace std;

void print( a ) {
    cout << a << endl;
}

int main() {
    for ( int i = 1; i <= 50; i++) {
        if ( i % 2 == 0 ) print( i );
    }

    return 0;
}

You forgot to declare the type of a when defining print.
