10.11 (Left Shifting Integers ) Left shifting an unsigned int by 1 bit is equivalent to multiplying the value by 2. Write function power2 that takes two integer arguments number and pow and calculates number * 2pow. You should declare pow as an unsigned integer , but remember that the result may be a negative value . Use the shift operator to calculate the result. Print the values as integers and as bits . Assume that an integer is of size 32 bits and that the default is to print from high to low order.

(Packing Characters into an Integer) The left-shift operator can be used to pack four character values into a four-byte unsigned int variable. Write a program that inputs four characters from the keyboard and passes them to function packCharacters. To pack four characters into an unsigned int variable, assign the first character to the unsigned intvariable, shift the unsigned int variable left by 8 bit positions and combine the unsigned variable with the second character using the bitwise inclusive OR operator....

KAM5 Write a function unsigned long long int factorial(int num) to compute the factorial of a number. The factorial of a number is given by n! = 1*2* ... *n So 1! = 1, 2! = 1*2, 3! = 1*2*3 ... For example: Test Result printf("%llu\n", factorial(5)); 120 printf("%lu\n", factorial(20)); 2432902008176640000

Prime Number Programing in C Note: The program is to be written using the bitwise operation. Use an integer array (not a Boolean array) and a bit length (for instance 32 bits). In this program you will write a C program to find all prime numbers less than 10,000. You should use 10,000 bits to correspond to the 10,000 integers under test. You should initially turn all bits on (off) and when a number is found that is not prime,...
