#include <iostream>

// A course is made up of four modules, each scored out
// of 25. The final course grade is the sum of the four
// module grades and is therefore scored out of 100.
//
// A module is passed if the student receives at least
// 13 out of 25.
//
// To pass the course, a student must satisfy BOTH of the
// following requirements:
//
//     1. Pass at least three of the four modules.
//
//     2. Receive a final course grade of at least 50
//        out of 100.
//
// Write a program that asks the user for the four module
// grades and prints either
//
//     Passed.
//
// or
//
//     Failed.
//
// If any entered module grade is less than 0 or greater
// than 25, immediately terminate the program by returning
// 0 from main().

// Function declarations
int main();

// Function definitions
int main() {
    return 0;
}









































// Hint:
//
// There are two separate requirements for passing the
// course:
//
//     final grade >= 50
//
// AND
//
//     at least three modules passed.
//
// You can calculate the final grade by adding the four
// module grades.
//
// To determine how many modules were passed, create an
// integer variable initially equal to zero:
//
//     int pass_count{ 0 };
//
// For each module with a grade of at least 13, increment
// this variable.









































// Here is one solution:
