Write a program that reads a file consisting of students’ test scores in the range 0–200. 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.

Question

Write a program that reads a file consisting of students’ test scores in the range 0–200. 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, 189

 

#include <iostream>

The output is correct but its still saying 0% when I run it. Anything wrong with it?
 
 
The image contains a list of numerical ranges and their corresponding values, which could represent a frequency distribution or histogram data. Here is the transcription: ``` 0-24: 1 25-49: 2 50-74: 0 75-99: 6 100-124: 1 125-149: 3 150-174: 5 175-200: 8 ``` At the bottom, there is a terminal prompt displaying "sandbox $", indicating that this data might be part of a command-line output or simulation environment. Explanation: - The numbers on the left represent different ranges or "bins." - The numbers on the right represent the frequency, or how many data points fall within each of those ranges. - For example, the range "175-200" has the highest count of 8, indicating more data points fall within this bin compared to others. - The range "50-74" has a frequency of 0, indicating no data points fall within this range.
