This is a C++ program which will take input of multiple arrays and will get sum up to generate a new array. We have also under taken few basic commands such as "gotoxoy" to arrange the output. The header files used in this are "iostream.h","conio.h","stdio.h","process.h". These are few basic commands whose perfect use can be learnt by a C++ student while viewing this post. This program can enhance ones knowledge related to process.h header file as it is not used more frequently. The proram is as follows:
#include<iostream.h>
#include<conio.h>
#include<stdio.h>
#include<process.h>
