Hello, Below is my current code. It works as intended but I would like to prompt the user to input the files name and open it that way instead of it being declared in the code itself. I tried a few things myself but couldnt gete it to work. Any help would be appricated. #include #include #include #include using namespace std; int main() { //open file ifstream file("StudentGrades.txt"); int number; string x; //declare array int *array = new int; int index = 0; //declare variable to store number of student int score24 = 0, score49 = 0, score74 = 0, score99 = 0, score124 = 0, score149 = 0, score174 = 0, score200 = 0; //Ensure array is not already full while (getline(file, x, ',')) { //convert to int number = stoi(x); //store it in a array array[index++] = number; } //check the every element and score based on score for(int i=0;i=0 && array[i] <=24) score24++; else if(array[i]>=25 && array[i] <=49) score49++; else if(array[i]>=50 && array[i] <=74) score74++; else if(array[i]>=75 && array[i] <=99) score99++; else if(array[i]>=100 && array[i] <=124) score124++; else if(array[i]>=125 && array[i] <=149) score149++; else if(array[i]>=150 && array[i] <=174) score174++; else if(array[i]>=175 && array[i] <=200) score200++; } //display score of the file cout<<"\nStudent test score from the file is: "<

Hello, Below is my current code. It works as intended but I would like to prompt the user to input the files name and open it that way instead of it being declared in the code itself. I tried a few things myself but couldnt gete it to work. Any help would be appricated.

#include <fstream>

#include<iostream>

#include <ctype.h>

#include <string>

using namespace std;

int main()

{

//open file

ifstream file("StudentGrades.txt");

int number;

string x;

//declare array

int *array = new int;

int index = 0;

//declare variable to store number of student

int score24 = 0, score49 = 0, score74 = 0, score99 = 0, score124 = 0, score149 = 0, score174 = 0, score200 = 0;

//Ensure array is not already full

while (getline(file, x, ','))

{

//convert to int

number = stoi(x);

//store it in a array

array[index++] = number;

}

//check the every element and score based on score

for(int i=0;i<index;i++)

{

if(array[i]>=0 && array[i] <=24)

score24++;

else if(array[i]>=25 && array[i] <=49)

score49++;

else if(array[i]>=50 && array[i] <=74)

score74++;

else if(array[i]>=75 && array[i] <=99)

score99++;

else if(array[i]>=100 && array[i] <=124)

score124++;

else if(array[i]>=125 && array[i] <=149)

score149++;

else if(array[i]>=150 && array[i] <=174)

score174++;

else if(array[i]>=175 && array[i] <=200)

score200++;

}

//display score of the file

cout<<"\nStudent test score from the file is: "<<endl;

for(int i=0;i<index;i++)

cout<<array[i]<<" ";

cout<<endl;

//display result

cout<<"\nScore ranges \t Number of students"<<endl;

cout<<"0-24 \t \t "<<score24<<endl;

cout<<"25-49 \t \t "<<score49<<endl;

cout<<"50-74 \t \t "<<score74<<endl;

cout<<"75-99 \t \t "<<score99<<endl;

cout<<"100-124 \t "<<score124<<endl;

cout<<"125-149 \t "<<score149<<endl;

cout<<"150-174 \t "<<score174<<endl;

cout<<"175-200 \t "<<score200<<endl;

cout<<endl;

//close the file

file.close();

}
