Question

CNIT 105 In Lab10 Due: By the end of your lab session OBJECTIVES: bitwise operations main () function: 1. Declare an int variable, name it number. 2. Prompt the user to enter a whole number- read it into the variable. Validate the range in a loop. Valid range is 20 to 200 both inclusive . 3. Display the number to the screen (base 10) 4, Display the number in hexadecimal (Use %X) 5. Display number to the screen -It will be a negative number. 6. Determine the rightmost bit in the number, display it to the screen (O or l): int maskRight-11 0000 0001 Do a bitwise & between the mamber and the maskRight If it is equal to 0, the rightmost bit is 0, otherwise, it is 1 7. Determine the third bit from the right in the number int mask3rd- 10? // 0000 0100 Do a bitwise & between the number and mask3rd-if it is equal to 0 the 3rd bit in the number is 0, otherwise it is 1. Shift the number to the left by 2 bits - display the updated number to the screen (It will be multiplied by 2 twice). 8. 9. Shifthe updated number to the right 3 bits -display the outcome to the screen. 10. Add the rerun loop to the program - allowing the user rerun the program with different input numbers. (Hint: do-while loop)

#include<stdio.h>

#include<stdlib.h>

int main()

{

int mask = 1,number,choice;

do

{

while(1)

{

printf("Enter a whole number between 20 and 200. inclusive : ");

scanf("%d",&number);

/*Check the input is with in the range of 20 and 200 */

if(number >= 20 && number <= 200)

{

break;

}

printf("\n");

}

printf("The input number is : %d\n\n",number);

/*Printing Hexadecimal value of a number*/

printf("The input number in Hexadecimal : %X\n\n",number);

/*Printing the negation value of a number */

printf("The ~number is : %d\n\n",~number);

/*Check whether the number lsb is zero or not Eg: (1000 0000) & (0000 0001)*/

(number & mask) ? printf("The right most bit is 1\n\n") : printf("The right most bit is 0\n\n");

/*Shift the mask to left 2 times to find the 3rd bit value */

mask = mask << 2;

/*Check whether the third bit is zero or not Eg: (1000 0000) & (0000 0100)*/

(number & mask) ? printf("The right most bit is 1\n\n") : printf("The right most bit is 0\n\n");

/*Shift the number two times left */

number = number << 2;

printf("Number after 2 bits shift to the left = %d\n\n",number);

/*Shift the number three times right */

number = number >> 3;

printf("Number after 3 bits shift to the right = %d\n\n",number);

printf("Do you want to continue this program and test a new number\n");

printf("Enter 1 for 'YES' and 0 for 'NO'. ");

scanf("%d",&choice);

printf("\n\n");

}while(choice);

return 0;
