Problem Statement

Write a C program to calculate Simple Interest given Principal, Rate of interest, and Time using formula SI = (P * R * T) / 100.

Input Format

Three space-separated values: Principal (float), Rate (float), and Time (float).

Output Format

Print the calculated Simple Interest rounded to 2 decimal places.

Constraints

0.0 < P, R, T <= 100000.0

Sample Input

1000 5 2

Sample Output

100.00

Explanation

SI = (1000 * 5 * 2) / 100 = 10000 / 100 = 100.00.

Starter Code

#include <stdio.h>

int main() {
    float p, r, t;
    if (scanf("%f %f %f", &p, &r, &t) == 3) {
        // Write your code here
    }
    return 0;
}

Limits

  • Time Limit: 1s
  • Memory Limit: 256MB

Embedded C Programming

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
