Problem Statement

Write a C program to calculate and print the area of a rectangle given its length and width.

Input Format

Two space-separated floating-point numbers representing length and width.

Output Format

Print the calculated area rounded to 2 decimal places.

Constraints

0.0 < Length, Width <= 1000.0

#include <stdio.h>

int main() {
    float l, w;
    if (scanf("%f %f", &l, &w) == 2) {
        // Write your code here
    }
    return 0;
}

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
