for part a

#include <stdio.h>

int main()
{
    int arr[4], i=0, sum=0;
    printf("Enter last 4 digit of your phone number");
    for (i=0; i<4; i++)
    {
      scanf("%d",&arr[i]);
    }
    for (i=0; i<4; i++)
    {
        sum = sum + arr[i];
    }
    printf(" Average is :" , sum/4);
    return 0;
}

for b part

#include<stdio.h>
#include<string.h>
struct student
{
    char name[20];
    int id;
    int hour_taken;
    int hour_passed;
    double gpa;
};
int main(void)
{
    printf(" Enter student name , id , hours taken, hours passed, GPA");
    scanf("%s %d %d %d %f", stu3.name, &stu3.id,stu3.hour_taken, stu3.hour_passed, stu3.gpa );
}
