Manipulations with Arrays

You can also use for loops in arrays to find the sum of all elements:


              12345678
            
int numbers[4] = {42, 12, 56, 98};
int sum = 0;

for (int i = 0; i <= 3; i++) {
&nbsp;&nbsp;&nbsp;&nbsp;    sum += numbers[i];
}

cout << sum;

Here the variable sum will store the sum of all elements, initially, it’s equal to 0. Then we iterate through the array using for loops and add each element to the variable sum.

You can also store in arrays the data from the user:
