Recap Challenge

Part of the Fundamentals section of Coddy's C journey — lesson 30 of 63.

Challenge

Easy

Create a program that analyzes a student's numerical score and provides feedback using multiple control flow techniques.

Your program should implement the following logic:

If the score is invalid (less than 0 or greater than 100), print "Invalid score" and exit.
Use a switch statement to print the letter grade:
- 90-100: "A"
- 80-89: "B"
- 70-79: "C"
- 60-69: "D"
- 0-59: “F”
Finally, use the ternary operator to print whether the student passed or failed (passing is 60 or above).

Try it yourself

#include <stdio.h>

int main() {
    int score;
    scanf("%d", &score);
    // Don't change above this line
    
    // Write your code here
    
    return 0;
}
