Program to check logical operations_3(set,clear bits in a particular number)
#include<stdio.h>
main()
{
int choice,num,bit;
printf("enter a num and bit\n");
scanf("%d%d",&num,&bit);
printf("enter any choice\n");
scanf("%d",&choice);
switch(choice)
{
case 1:
printf("set bit\n");
num=num|(1<<bit);
printf("number is %d",num);
break;
case 2:
printf("clear bit\n");
num=num&~(1<<bit);
printf("number is %d",num);
break;
case 3:
printf("complement bit\n");
num=num^(1<<bit);
printf("number is %d",num);
break;
case 4:
printf("test bit\n");
num&(1<<bit)?printf("set"):printf("clear");
break;
case 5:
printf("exit");
break;
default:
printf("eneter currect choice\n");
}
//printf("number is %d",num);
}
