HELP I dont know what Ive done wrong. It does the program it just doesnt count the students and test scores.

write a program that reads a file consisting of student's tests 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.)
Explanation / Answer
you have done error in void findNumberOfStudentsInEachRange(int score[], int range [])
you forgot to add condition for scores from 150-174
else if (testScore >= 150 && testScore <= 174)
range[6]++;
please find the corrected code
i have tested the below code inhttp://www.tutorialspoint.com/compile_cpp11_online.php ita working fine if you remove pause statements
#include<iostream>
#include<fstream>
#include<iomanip>
#include<string>
using namespace std;

int numberOfStudents;
int main()
{

int range[TOTAL_RANGES];
cout<<"Enter the file name:";
cin>>fileName;
inFile.open(fileName);
if(!inFile)
{
cout<<"The file"<<fileName<<"is not found."<<endl;
system("pause");
return 1;
}
readTestScores(inFile, score);
findNumberOfStudentsInEachRange(score, range);
displayResult(score, range);
inFile.close();
system("pause");
return 0;
}
void readTestScores(ifstream &inFile, int score[])
{
int testScore;
inFile>>testScore;

}
}
