Problem statement

In this problem, we have to find the maximum, minimum and average of 4 subjects using structures .

We will implement this problem in C Programming Language.

Approach to solve

Following is the approach to solve the problem:

• First we create a structure data type and declase all the variables.
• Next inside the main function we take the input of roll number, age and marks of 4 subjects.
• Then we find out the maximum and minimum marks using if statement.
• We also have to find the average of the marks by adding all the marks and dividing by 4.0.
• Then we print all the values.

Implementation

Following is the implemention of the code in C programming language:

#include<stdio.h>
struct data
{
	int rollno;
	int age;
	int mark[4];
}
s;
int main()
{
	double avg,total;
	printf("enter roll");
	scanf("%d",&s.rollno);
	printf("enter age");
	scanf("%d",&s.age);
	printf("enter the marks");
	for(int i=0;i<4;i++)
	{
		scanf("%d",&s.mark[i]);
	}
	int max=s.mark[0];
	int min=s.mark[0];
	for(int i=0;i<4;i++)
	{
	if(s.mark[i]>max)
	max=s.mark[i];
	if(s.mark[i]<min)
	min=s.mark[i];
	total+=s.mark[i];
	}
	avg=total/4.0;
	printf("max is%d",max);
	printf("min is %d",min);
	printf("total is %lf",total);
	return 0;
}

Output

Run the code as follows:

gcc code.c
./a.out

Following is the output of the program:

enter roll7
enter age18
enter the marks98
78
67
99
max is99min is 67total is 342.000000
