Structure Type Data as Input and Output Parameters:

Structure variables can be passed to functions as parameters in the same manner
as other variables. When a structure is passed to a function, a copy of the
structure is made unless pointers are used.

Structures can also be returned from functions, allowing multiple related values
to be passed back to the calling function as a single unit. This capability
enhances modularity and clarity in program design.

EXAMPLE:

#include <stdio.h>

struct Tin {
    int id;
    float weight;
    char grade;
};


void display(struct Tin t) {
    printf("ID: %d | Weight: %.2f | Grade: %c\n", t.id, t.weight, t.grade);
}

int main() {
    struct Tin t1 = {101, 250.5, 'A'};
    display(t1);
    return 0;
}
