Question

Write a method with the signature "float sumArray(float[] data)" that takes an array of floats, and returns their sum.

Answer 1

I will code in JAVA.

Preconditions:

• The float array of data are declared and initialized.

public float sumArray(float[] data) {

float sum = 0;

for(int i = 0; i < data.length; i++) {

sum = sum + data[i];

}

return sum;

}

Step-by-step explanation:

First, you have to declare a variable sum of type float and initialize with 0. In addition, this method has a for-loop to go through whole array of data and each element is added to the float value to sum. When the for loop ends, the sum variable is returned.
