    Miracle C - Strutures

    Does anyone know how to pass structures to and from a funtion in miracle c? this is the code for turbo C++ i think but it not work because of the diffrences in compiler. any ideas?

    cheers

    <code>
    #include <stdio.h>

    struct exam {
    int mark;
    float av;
    }result;

    struct exam grade(void);

    void main()
    {
    result=grade();
    printf("%d, %f", result.mark, result.av);
    }

    struct exam grade(void)
    {
    struct exam temp;

    temp.mark = 100;
    temp.av = 123.23;

    return temp;
    }

    Miracle C is a C compiler, Turbo C++ is a C++ compiler. This is an important difference.

    Function main() should be of type int and return an int-value.

    What does not work on your code or what errors does your compiler give? I've compiled it with GCC and have no problems.

    About passing a structure:

    Code:
    /* When structure is only used for its info, pass it by value */
    void function (struct exam result)
    {
        printf("%d, %f", result.mark, result.av);
    }
    
    /* When adaptation of structure is necessary use pointer to struct */
    void function (struct exam *result)
    {
        result->mark = 1;
        result->av = 1.0;
    }
