Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print: 7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. (Notes) Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). See "How to Use zyBooks".

Answer:

#include <iostream>

using namespace std;

int main() {

   int courseGrades[50],NUM_VALS;//coursegrades and numvals variables declared.

   cout<<"Enter the NUM_VALS"<<endl;

   cin>>NUM_VALS;//taking input of the NUM_VALS.

   cout<<"Enter the course Grades"<<endl;

   for(int i=0;i<NUM_VALS;i++)

   cin>>courseGrades[i];//takin input of the course grades.

   for(int i=0;i<NUM_VALS;i++)

   {

       cout<<courseGrades[i]<<" ";//printing the course grades forward.

   }

   cout<<endl;

   for(int i=NUM_VALS-1;i>=0;i--)//printing the course grades backward.

   {

       cout<<courseGrades[i]<<" ";

   }

return 0;

}

Output:-

Enter the NUM_VALS

4

Enter the course Grades

7 9 11 10

7 9 11 10  

10 11 9 7

Explanation:

The above written code is in C++.

I have declared an array courseGrades and a variable NUM_VALS. Then first taking input of the NUM_VALS then taking the input of the courseGrades.Then the first loop is for printing tin forward direction then the other loop is for printing kin backward direction.
