Ashish if statements require boolean values to be evaluated as a condition, so you need a function which returns a boolean. E.g. bool always_true() { return true; } // in main if (always_true()) { std::cout << "Yes"; }

Ashish I'm not too sure what you mean by "pass function in if". Can you type a snippet and share it so I get what you are trying to achieve? For now, I imagine: if (something) { // function call here } or do you mean if (function()) { // body }

Ashish If statements will always evaluate its arguments as boolean. You can feed it with functions returning integers, or just integers or other datatype which can be casted to boolean. if (3939) { .... }
