Answer to Question #275537 in C++ for Chris

Question

Write a program that declare an array of size 25 consisting of students’ test scores in the range 0–200. The user may input any score in the array. It should then determine the number of students having scores in each of the following ranges: 0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200. Output the score ranges and the number of students. (Run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157)

Answer 1

#include <iostream>
#include <vector>


int main()
{
    int score[25] = {};
    std::cout << "Enter ther score 25 times: " << std::endl;
    for (int i = 0; i != 25; ++i)
    {
        std::cin >> score[i];
    }
    std::vector <std::pair <int, int>> ranges = {{0,24}, {25,49}, {50,74}, {75,99}, {100,124}, {125,149}, {150,174}, {175,200}};

    for (int i = 0; i!= 25; ++i)
    {
        for(auto& el: ranges)
        {
            if (score[i] <= el.second && score[i] >= el.first)
            {
                std::cout << "Student number " << i+1 << " with the score " << score[i] << " is in range "<< el.first << " - " <<el.second <<std::endl;
                
            }
        }
    }
    return 0;
