Chapter 2, Problem 2.63HW

Fill in code for the following C functions. Function srl performs a logical right shift using an arithmetic right shift (given by value xsra), followed by other operations not including right shifts or division. Function sra performs an arithmetic right shift using a logical right shift (given by value xsr1), followed by other operations not including right shifts or division. You may use the computation 8*sizeof (int) to determine w, the number of bits in data type int. The shift amount k can range from 0 to w – 1.'

unsigned srl(unsigned x, int k) {

/* Perform, shift arithmetically */

unsigned xsra = (int) x >> k;

Q: Write a C program code for matrix multiplication (C = AB)with following features: • The program should take the number of row and columns from user in one function funct_check() for the two matrices A and B. • These dimensions (#rows and #columns) should be checked whether the two matrices can be multiplied or not based on No. of columns in first matrix = number of rows in second matrix If A&B cannot be multiplied the program should just display "The two matrices cannot be multiplied" and return. Else if the matrices can be multiplied, funct_check() should call another function, funct_multiply() to take the input from user for elements of matrices and compute the result of matrix multiplication and store that in another matrix C. • Finally display the resultant matrix C.
Assignment Write a program to calculate n! for a given number n and perform the simple calculator operations. The valid operations of the calculator are: + add - sub * mul I div The program must contain a function fact with one input parameter that returns the factorial of a number, a function add that performs the addition of two numbers, a function sub that performs the subtraction of two numbers, a function mul that performs the multiplication of two numbers, a function div that performs the division of two numbers. The program must also check for bad input data. Make sure when you pass parameters you pass the addresses (not the value). • All function return type must be of type void. • Take inputs in main function. • Pass the addresses of the operands and the address of the result to each function. Output must be displayed as follows: 1: Addition 2: Subtraction 3: Multiplication 4: Division 5: Factorial 6: Quit Enter the choice => 1 Enter two numbers => 2, 3 Sum => 5
integer) Write a function that computes the sum of the digits in an integer. Use the following function header:def sumDigits(n):For example, sumDigits(234) returns 9 (Hint: Use the % operator to extract digits, and the // operator to remove the extracted digit. For instance, toextract 4 from 234, use 234 % 10 To remove 4 from 234, use 234 // 10 (=23) Use a loop to repeatedly extract and remove the digits until all the digits are extracted.) Write a test program that prompts the user to enter an integer and displays the sum of all its digits.
