Question

Given an array of primitive integers named grades, fill in the blank to complete the following code that calculates the average of all the grades: double average = 0; average + grades[ average (= grades.length; Use proper spacing per the course style guide. Do not include additional spaces at the beginning or end.

Answer 1

Answer:

C++ snippet is given below with appropriate comments and explanation

Explanation:

Code snippet:

double average=0;//declaring variable

      //using for loop

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

      {

      average+=grades[i];//add each grade to average

      }

      average/=grades.length;//find average

Explanation :

Above code snippet need a for loop to add each grade from the array to the variable average,

average/=grades.length; this will compute average.
