Concept: Array

Write a program to create two integer of size 8 and 7. Initialize the arrays with random values. Sort the arrays in ascending order with the help of user defined function namely “sort array”. Merge these arrays with the help of another user defined function named “merge arrays” which returns a new array. Program should display the arrays before and after sorting, also the merged arrays.
