Create a structure

Use an integer called mode. When mode equals one, display your name. If the mode is two, then display your department. This mode variable needs to be declared as a member of the union. Write a C program:

Use the following union

union integer

{

int mode;

};

Sample Input and Output:

Enter your name

Mukesh

Enter your department

CSE

Enter integer mode

1

The mode says Mukesh

Implementation of above problem:

#include<stdio.h>

union integer

{

int mode;

};

union integer i;

int main()

{

char name[100],dep[100];

printf("Enter your name\n");

scanf("%s",name);

printf("Enter your department\n");

scanf("%s",dep);

printf("Enter integer mode\n");

scanf("%d",&i.mode);

if(i.mode==1)

printf("The mode says %s\n",name);

else 

printf("The mode says %s\n",dep);     

return 0;

}
