How do I write this

Question

8-2. Write a program named studentAverage that prompts user for the number of students in a class. Store that
number in an integer variable called numStudents. Prompt the user to enter the final exam grade as an integer
value between 1 and 100 for each student and save those grade values in an integer array called grades. Iterate
through the array and display each student’s final exam grade, and then display the class average.
Expected Output if 3 students entered with following grades: 89, 95, 70
89
95
70
Class Average = 84.67

Answer 1

Code in C:

#include<stdio.h>

 

main() {

// declaring numStudents variable
int numStudents;

 

// taking num of students in the class as input from the user
printf("Enter the number of students in the class:");
scanf("%d",&numStudents);

 

// declaring array class and variables
int arr[numStudents], i, sum;
float avg;
printf("\nEnter the grades(1-100) for each student in the class:\n");

 

// taking grades as input from the user
for (i=0;i<numStudents;i++)
scanf("%d",&arr[i]);
sum = 0;

// finding sum of grades
for (i=0;i<numStudents;i++)
sum += arr[i];

 

// finding average of class
avg = (float)sum/(sum)numStudents;

 

// displaying result
printf("\nClass average %.2f",avg);
return 0;
