Array crashing program

[Miyo123]

Write your question here.

  void buildSalesArray(double salesArray[])
 {
 int Month = 0;
 double Amount = 0;
 ifstream ifs ("sales7.txt");

  char c = ifs.get();
   if (ifs.fail() )
   {
   cout << "The sales7.txt input file did not open";
   exit(-1);
   }
  while (!ifs.eof()) 
  {
  ifs >> Month >> Amount;
  cout << "Month: " << Month << "Amount: " << Amount << endl;
  salesArray[Month] += Amount; // i'm having trouble here
  cout << "Array: " << salesArray[Month] << endl;
  }
  
  ifs.close();
 }

My program is crashing at a certain point and any suggests why would be greatly appreciated!

What is the size of the array? The program crashing could be it exceeding the bounds of the array.

[Miyo123]

this is my main:
#include <iostream>
#include <iomanip>
#include <fstream>
#include <cstdlib>
#include <string>

using namespace std;
const int NUM_MONTHS = 12;
const string MONTH_NAMES[NUM_MONTHS+1] = { "", "January", "February", "March",
"April", "May", "June", "July", "August", "September",
"October", "November", "December" };
void buildSalesArray(double salesArray[]);
void printSalesArray(double salesArray[]);
double findSum(double salesArray[]);
double findMean(double salesArray[]);
int findHighMonth(double salesArray[]);
int findLowMonth(double salesArray[]);
int main()
{


double salesArray[NUM_MONTHS+1] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

buildSalesArray(salesArray);
printSalesArray(salesArray);
findSum(salesArray);
findMean(salesArray);
findHighMonth(salesArray);
findLowMonth(salesArray);
return 0;
}

  char c = ifs.get();
   if (ifs.fail() )

You shouldn't check like this to see if the file opened or not. Try: if(!ifs.is_open())

salesArray[Month] += Amount; // i'm having trouble here it would help if we could see the text file you are trying to read.
