 This is the program to find the sum of n number in c using a for loop

What is for loop?

       The for loop is the easiest looping statement which allow code to be executed repeatedly.

It contains three different statements (initialization, condition or test- expression and update expression(s))

separated by semicolon(;).

# include <iostream>

using namespace std;

int main()

{

    int n,sum=0,i;

    cout<<"Enter how many number to be add:";

    cin>>n;

    int num[n];

    for( i=1;i<=n;i++)

    {

        cout<<"Enter the number"<<i<<":\t";

        cin>>num[i];

        sum=sum+num[i];

    }

    cout<<"THe sum of numbers are\t"<<sum;

    return 0;

}

OUTPUT
:

Enter how many numbers to be add:4

Enter the number1: 34

Enter the number2: 3

Enter the number3: 34
