In this article we will learn to implement a C program to demonstrate union. A C program is provided below to illustrate the concept of unions in C language.
Program is as follows:
/*
* C program to demonstrate union
* Author: P.S.SuryaTeja
*/
#include <stdio.h>
#include <conio.h>
#include <math.h>
#include <stdlib.h>
union student
{
int id;
char name[20];
};
int main(int argc, char **argv)
{
union student st[10];
int n, i;
printf("Enter a number between 1 to 10: ");
scanf("%d", &n);
for(i = 1; i <= n; i++)
{
printf("\nEnter details of student %d:", i);
printf("\nId of student %d: ", i);
scanf("%d", &st[i].id);
printf("\nStudent %d Id: %d", i, st[i].id);
printf("\nName of student %d: ", i);
fflush(stdin);
gets(st[i].name);
printf("\nStudent %d Name: ", i);
puts(st[i].name);
}
getch();
return 0;
}
Input and output for the above program is as follows:
Enter a number between 1 to 10: 2
Enter details of student 1:
Id of student 1: 101
Student 1 Id: 101
Name of student 1: teja
Student 1 Name: teja
Enter details of student 2:
Id of student 2: 102
Student 2 Id: 102
Name of student 2: sruthi
Student 2 Name: sruthi
