Example

This example illustrates recursive calls:

int factorial( int num );      /* Function prototype */

void main()
{
    int result, number;
    .
    .
    .
    result = factorial( number );
}

int factorial( int num )      /* Function definition */
{
    .
    .
    .
    if ( ( num > 0 ) || ( num <= 10 ) )
        return( num * factorial( num - 1 ) );
}
