Write a C++ program that calculates student grades based on percentage marks: >= 90 (‘A’), >= 80 (‘B’), >= 70 (‘C’), >= 60 (‘D’), else (‘F’).
A single integer Marks (0 to 100).
Print the corresponding grade letter (A, B, C, D, or F).
0 <= Marks <= 100
85
B
Uses chained if-else conditions to determine grading brackets.
#include <iostream>
int main() {
int marks;
if (std::cin >> marks) {
// Write your code here
}
return 0;
}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
