public static string PercentageMarks(int marks) to returns percentage wrt marks
Use GradeMethod in the main function to display the grades and percentage of the marks calculated
#include <iostream>
#include <cctype>
#include <limits>
int main()
{
std::cout << "Do you want someone to do all the work for you? ";
char answer{};
std::cin >> answer;
std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
if (std::toupper(answer) == 'Y' ) { std::cout << "Post it in the Jobs section.\n"; }
else { std::cout << "Show what you have coded so far.\n"; }
