In this article, we will write a c program to calculate the total and percentage marks of a student using Structure.

Write a C Program to Calculate Total and Percentage Marks of a Student Using Structure

#include <stdio.h>
#include <conio.h>

struct student
{
	int rl;
	char nm[20];
	int m1;
	int m2;
	int m3;
	int t;
	float per;
};
void main()
{
	struct student a;
	clrscr();
	printf(" Enter RollNo, Name amd three sub marks\n");
	scanf("%d%s%d%d%d", &a.rl, &a.nm, &a.m1, &a.m2, &a.m3);
	a.t = a.m1 + a.m2 + a.m3;
	a.per = a.t / 3.0;
	printf("rollno=%d\n", a.rl);
	printf("Name=%sk\n", a.nm);
	printf("m1=%d\n", a.m1);
	printf("m2=%d\n", a.m2);
	printf("m3=%d\n", a.m3);
	printf("total=%d\n", a.t);
	printf("per=%f\n", a.per);
	getch();
}

Input:

Enter RollNo, Name and three sub marks
 12 rama 30 40 50

Output:

rollno=12
Name=rama
m1=30
m2=40
m3=50
total=120
per=40.000000
