Question

Instead of using two different variables, however, we will define a structure with two members; one representing the feet and the other one representing the inches. We will also use three functions; one to initialize a structure, another one to check the validity of its values, and one last one to print them out.
First, go ahead and define your structure. Next, declare a structure of this type inside the main. Then, call your first function (the initialization function). This function will be of type structure, it will receive zero parameters and it will return a structure. Inside the function, ask the user for the height of the student. In other words, you will use this function to initialize the structure you have in the main. When done, call a second function (the checking function). To this function, you will send your structure. The function will not return anything and it will validate the values inputted by the user. If any of the values is not in the right range (between 5’ 8” and 7’ 7”), display an error message and exit the program. Make sure to also check for negative values.
Lastly, if the program didn’t exit, call the last function (the printing function). This function will receive a structure, it will not return anything and it will display the values of the two members of the structure.

Use C code to solve this problem.

Answer 1

Code:

#include <stdio.h>
struct Height{
    int feet;
    int inches;
};

struct Height initializeStructure(){
    struct Height h;
    printf("Enter feet: ");
    scanf("%d", &h.feet);
    printf("Enter inches: ");
    scanf("%d", &h.inches);
    return h;
}

void verifyHeight(struct Height h){
    int inches = h.feet * 12 + h.inches;
    if(inches <= (5*12 + 8) || inches >= (7*12 + 7)){
        printf("Height entered is invalid");
        exit(0);
    }
}

void printHeight(struct Height h){
    printf("\nHeight:\tFeet = %d Inches = %d\n", h.feet, h.inches);
}

int main(){
    struct Height h1;
    h1 = initializeStructure();
    verifyHeight(h1);
    printHeight(h1);
    return 0;
}

Output:
