    int year;

    printf("Enter a year: ");
    scanf("%d",&year);

    if(year%4 == 0)
    {
        if( year%100 == 0)
        {
            // year is divisible by 400, hence the year is a leap year
            if ( year%400 == 0)
                printf("%d is a leap year.", year);
            else
                printf("%d is not a leap year.", year);
        }
        else
            printf("%d is a leap year.", year );
    }
    else
        printf("%d is not a leap year.", year);
    
    return 0;
}

Output

Enter a year: 2012
2012 is a leap year.

Explanation

C Program to Add Two Complex Numbers by Passing Structure to a Function

In the structure complex, we are using float datatype for variables, real and imag since our concern is to add any two complex numbers with a possible fractional value.

In the main() function, the real part and the imaginary part of the complex numbers are taken separtely using scanf().

The structures n1 and n2 are passed as an argument of function add(). The function computes the sum and returns the structure variable temp to the main() function.

The final result is printed using printf() throught the main() function.
