Need help with making the graph like it is in the correct_output.txt 

here is a snippet of my code
 // Prints a scaled bar relevant to the maximum value in the samples array
void printBar(int val, int max) {
    int i;
    int barlength = GRAPH_WIDTH * val / max;
    cout << "| ";
    for (i = 0; i < barlength; ++i) {
        cout << "*";
    }
    cout << " ";
    printInt(val, 0);  // Print the sample value right next to the bar
    cout << " |" << endl;  // Adjusted the formatting
}

 
// Prints a graph comparing the sample values visually
void printGraph(int samples[], int noOfSamples, const char* label) {
    int max = findMax(samples, noOfSamples);
    labelLine(GRAPH_WIDTH + 10, label);
    for (int i = 0; i < noOfSamples; ++i) {
        printBar(samples[i], max);
    }
    line(GRAPH_WIDTH + 10);
}
and here is the whole set of code that I made with it

           cout << "\\ " << (i + 1) << "/" << noOfSamples << " : ";
           samples[i] = getInt(1, 1000000);
       }
   }

   // Finds the largest sample in the samples array, if it is larger than GRAPH_WIDTH,
   // otherwise, it will return GRAPH_WIDTH.
   int findMax(int samples[], int noOfSamples) {
       int max = samples[0];
       for (int i = 1; i < noOfSamples; ++i) {
           if (max < samples[i]) max = samples[i];
       }
       return max < GRAPH_WIDTH ? GRAPH_WIDTH : max;
   }

   // Prints a scaled bar relevant to the maximum value in the samples array
   void printBar(int val, int max) {
       int i;
       int barlength = GRAPH_WIDTH * val / max;
       cout << "| ";
       for (i = 0; i < barlength; ++i) {
           cout << "*";
       }
       cout << " ";
       printInt(val, 0);  // Print the sample value right next to the bar
       cout << " |" << endl;  // Adjusted the formatting
   }

 
   // Prints a graph comparing the sample values visually
   void printGraph(int samples[], int noOfSamples, const char* label) {
       int max = findMax(samples, noOfSamples);
       labelLine(GRAPH_WIDTH + 10, label);
       for (int i = 0; i < noOfSamples; ++i) {

       }
