Problem Statement

Write a C program using structures and arrays to calculate total and percentage marks for N students.

Input Format

First line: N. Next N lines: Name followed by 3 subject marks.

Output Format

Print name, total, and percentage formatted to 2 decimal places.

Constraints

1 <= N <= 50, 0 <= Marks <= 100

Sample Input

2
John 80 85 90
Alice 90 95 92

Sample Output

John Total: 255 Percentage: 85.00%
Alice Total: 277 Percentage: 92.33%

Explanation

Calculates sum of 3 subjects and average percentage per student.

Starter Code

#include <stdio.h>

struct Student {
    char name[51];
    int m1, m2, m3;
};

int main() {
    int n;

        struct Student s[n];
        for (int i = 0; i < n; i++) {
            scanf("%50s %d %d %d", s[i].name, &s[i].m1, &s[i].m2, &s[i].m3);
        }

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
