Thread: 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;
}

</code>

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;
}
