LAB EXPERIMENT NO. __01_____ LIST OF TASKS
(^01) Q. Create an array of length 10 of integers. Values ranging from 1 to
Find all pair of elements whose sum is 25.
Find the number of elements of A which are even, and the number of elements of A which are odd.
Write a procedure which finds the average of the value of A.
Write a procedure which adds an element in an array at a given index. Take the value to add and the index from the user by using Shift down technique.
Write a procedure which looks for 2 numbers 45 and 14 in an array and delete them if they are present in the array by using Shift up technique. (^02) 1. Write a program which input 2 matrix of user defined rows and columns and perform following operation a. Display/Print as a Matrix
