Question

The following is a structure template:

struct box

{

char maker[40];

float height;

float width;

float length;

float volume;

};

a. Write a function that has a reference to a box structure as its formal argument

and displays the value of each member.

b. Write a function that has a reference to a box structure as its formal argument

and sets the volume member to the product of the other three dimensions.

Answer 1

#include <stdio.h>
#include <string.h>

struct box {
    char maker[40];
    float height;
    float width;
    float length;
    float volume;
};

// a. Write a function that has a reference to a box structure as its formal argument
//and displays the value of each member.
void print(struct box *b) {
    printf("Maker: %s\n", b->maker);
    printf("Height: %f\n", b->height);
    printf("Width: %f\n", b->width);
    printf("Length: %f\n", b->length);
    printf("Volume: %f\n", b->volume);
}

//b. Write a function that has a reference to a box structure as its formal argument
//and sets the volume member to the product of the other three dimensions.
void set_volume(struct box *b) {
    b->volume = b->height*b->width*b->length;
}

int main() {
    struct box b;
    strcpy(b.maker, "Maker");
    b.length = 2;
    b.width = 7;
    b.height = 5;
    set_volume(&b);
    print(&b);
    return 0;
