C query

Suppose i have predefine array of elements. I want to calculate the sum of first five elements, then display it & then calculate the sum of next elements & so on till last.

 

[AngleWyrm]

// given an array and an index, return sum of next five elements
double sumNextFiveElements(double[] array, int index)

Can you please provide me the code

I write in Java not C, so I cannot give you the code, only an algorithm.

// loop through segments of the array (assumes array length divisible by 5)
for(int offset = 0; offset < array.size(); offset += 5){
    // gather elements of segment
    for(int index = offset; index < offset + 5; index++){
        total += array[index]
    }
    // could print total here, and then reset total if desired
}

It's ok you can provide java code too

Thank you so much

for(int i= 0; i < arr.size(); i += 5)
{
    for(int j = i; j < i+ 5; j++){
        sum += arr[j];
    }
    cout<<sum<<endl;
}
