Question

Programing C

Create union integer with members char c, short s, int i and long l. Write a program

that inputs values of type char, short, int and long and stores the values in union

variables of type union integer. Each union variable should be printed as a char, a

short, an int and a long.

Make sure that the correct values are printed as shown below in the example

An example interaction:

Enter a char: A

The char is: A

Enter a short int: 12

The short int is: 12

Enter an int: 145678

The int is: 145678

Enter a long int: 23001001034

The long int is: 23001001034

Answer 1

Code:

#include <stdio.h> 
  
union integer { 
    char c;
    short s;
    int i;
    long l;
} I; 
  
  
int main() 
{ 
    printf("Size of union integer = %lu\n", sizeof(I));
    printf("Enter a char: ");
    scanf("%c", &I.c);
    printf("The char is: %c \n", I.c);
    
    printf("Enter a short int: ");
    scanf("%hd", &I.s);
    printf("The short int is: %hd \n", I.s);

    printf("Enter an int: ");
    scanf("%d", &I.i);
    printf("The int is: %d \n", I.i);
    
    printf("Enter a long int: ");
    scanf("%ld", &I.l);
    printf("The long int is: %ld \n", I.l);
    
    return 0; 
} 

Output:
