Referring back to your Assignment \#1: Algorithm and Flowchart of Modular Multiplication. Now use the branch/selection and loop syntax, such as while, do...while, switch..case, if...else, do a programming to compute the modular multiplication algorithm as described in pseudo code below: a. Ask the user to key in three positive integer, x,y, and M, separately. If user key in 0 to any of the input, then exit the program. (You need to do necessary error control in case the user key in an invalid input, such as a negative number or a character)
