44. WAP to scan a number and bit position from the user also display a menu for set, clear and compliment of bit. Take a menu selection input from user, depend on the selection perform the task and display the results.

 

#include<stdio.h>

void main()

        int num,pos,op,c=0;

        printf("Enter the number : \n");

        scanf("%d",&num);

        scanf("%d",&pos);

        if(pos>=0 && pos<=31)

        {

                printf("Select the option \n 1) Set a bit \n 2) Clear a bit \n 3) Toggle a bit\n");

                scanf("%d",&op);

                if(op==1)

                {

                        num=num|(1<<pos);
