the sum and average of given numbers using Arrays

"Write a program in C++ to find the sum and average of given numbers using Arrays."

Re: the sum and average of given numbers using Arrays

Ok here it is:
Code: cpp

`#include <iostream>#include <conio.h>using namespace std;int main (int argc, char *argv[]){    int num[100];    int n;    register int i;    int sum = 0;    float avg;    cout << "Enter number of items in array: ";    cin >> n;    for (i = 0; i < n; i++)    {        cout << "Enter the " << i+1 << "th number: ";        cin >> num[i];        sum += num[i];    }    avg = (float) sum/n;    cout << "Sum is " << sum << "\nAnd Average = " << avg;    getch();}`

But if you wanna learn programming for yourself, try coding it yourself. I have given you the program, get the idea from it and try to write your code yourself.
Anyway, its my first try on C++, had never coded in C++.

Re: the sum and average of given numbers using Arrays

Dear Friend,

The following coding to calculate the sum and average of an array element using C program.

Code:

```#include<stdio.h> main () {     int array[100];     int n,i,sum=0;     float avg;     printf("Enter number of elements in array:\n");   scanf("%d",&n);   for (i = 0; i < n; i++)     {         scanf("%d" ,&array[i]);         sum += array[i];     }     avg = (float) sum/n;  printf("The sum is :%d\n",sum);  printf("The sum is :%f\n",avg); }```
