Ternary Operator

Here is a program that takes the marks from a student (out of 100), and converts it to a grade. Use ternary operators to output the students grade.

A for marks >= 90 B for marks >= 70 and < 90 C for marks >= 50 and < 70 D for marks < 50

This is not a great use for ternary operators, but it will improve your capability of using them.

#include <iostream>

int main() 
{
	std::cout << "Input your marks";
	int marks;
	std::cin >> marks;
	std::cout << "Your grade is: " << /*Your ternary operators here*/;
}

Answer

#include <iostream>

int main() 
{
	std::cout << "Input your marks";
	int marks;
	std::cin >> marks;
	std::cout << "Your grade is: " << 
    (marks >= 90 ? "A" 
    : (marks >=70 ? "B" 
    : (marks >= 50 ? "C" : "D")));
}
