Question

I want to use enum as function return type or as a argument. But when I give it as is, it’s giving error message. But if I typedef the same, it’s working fine.

#include <stdio.h>

enum        // if *typedef enum* is used instead, it's working fine
{
    _false,
    _true,
} bool;

bool func1(bool );

int main()
{
    printf("Return Value = %d\n\n", func1(_true));

    return 0;
}

bool func1(bool status)
{
    return status;
}

Please help me understand this. Thank you.

You are not making a new type bool, instead you are declaring a variable named bool.
