PROBLEM 26:

Write a C program to keep records and perform statistical analysis for a
class of student. The class may have up to 5 student . There are five quizzes during the term. Each
student is identified by a four-digit student number. The program will print the student scores and
calculates and print the statistics(high score,low score and average score ) for each quiz . The output

is in the same order as input ; no sorting is required .

CODE:

#include<stdio.h>
void stu1(int array[],int size);
main(){
    // Variable declaration//
    int array[5];
    int student[5];
    int i=150999;
 /*Input*/
printf("Enter first student id:");//here get input stduent id
scanf("%d",&student[0]);
printf("enter student %d five quiz marks\n",student[0]);//here input students quiz marks
stu1(array,5);//here I call function which I declare
printf("Enter second student id:");
scanf("%d",&student[1]);
printf("enter student %d five quiz marks\n",student[1]);
stu1(array,5);
printf("Enter third student id:");
scanf("%d",&student[2]);
printf("enter student %d five quiz marks\n",student[2]);
stu1(array,5);
printf("Enter fourth student id:");
scanf("%d",&student[3]);
printf("enter student %d five quiz marks\n",student[3]);
stu1(array,5);
printf("Enter student id:");
scanf("%d",&student[4]);
printf("Enter student %d five quiz marks\n",student[4]);
stu1(array,5);
}
 /* actual Working */
void stu1(int a[],int size)
{
    int i,max,k=0,min;
    float avg,total;
    for(i=0;i<size;i++)//here loop will run until not equal to size where size is given 5
    {
        printf("quiz %d marks:\n",i+1);//quiz marks save in a array
        scanf("%d",&a[i]);
    }
    for(i=0;i<5;i++)//here loop will count total quiz numbers for average
    {
        total=total+a[i];
    }
    max=a[0];
    for(i=0;i<5;i++)//this loop will find max number
    {
       if(a[i]>max)
       {
           max=a[i];
       }
    }
    min=a[0];
    for(i=0;i<5;i++)//this loop will find minimun number
    {
        if(a[i]<min)
        {
            min=a[i];
        }
    }
    avg=total/5;//here average will calculate
//printf("total is:%d\n",total);
printf("Hightest is:%d\n",max);
printf("Lowest is:%d\n",min);
printf("average is:%f\n",avg);
return 0;

}

Program Output:

YOU have to enter 5 stduents five quiz marks if you want to take more than 5 students so just edit this code.
