C++ Input File Reading Help!

Hello guys,

I am new in this forum and i hope im gonna get some fast help.

I have this problem where i should input numbers from a .doc file, and the program should output how many times the number of occurences of each number.

ie: the numbers in the .doc file are 2,3,6,8,9,2,1,1,3,1.

The program should read the numbers from the file and outputs the following:
Number 1 = 3
Number 2 = 1 ... and so on.

I started with the following but im getting stuck.
Any help please??

Code:

#include<iostream>
#include<fstream>
#include<iomanip>
using namespace std;

int main()
{

int array[10000];
int n;

ifstream numbers( "numbers.doc", ios::in); 

if(!numbers)
{
cerr << endl << "File could not be opened" << endl;
system("pause");
exit(1);
}

for (int i=0, i<10000, i++)
array[i] = 0; //initializes array

for (i=0, i<50, i++)
{
if (i=1)
array[n] += array[i];
cout << array[i];
}
{
if (i=2)
array[n] += array[i];
cout << array[i];
} 

results.close();

return 0;
}

///and so on.

My program is not working and i neeed someone please to help me fix it ASAP,

Thanks in advance.

>> if (i=1)
The = operator assigns a value to variables, in this case it sets the value of i to one. What you're wanting here is the equality operator, which is ==. Same case with your if(i=2)

Twomers' response is gold.

And, this is a canned, dry response to any question, but try to indent your code. Perhaps the forum undid whatever formatting you had, or perhaps not.

Code:

#include<iostream>
#include<fstream>
#include<iomanip>
using namespace std;

int main()
{

   int array[10000];
   int n;

   ifstream numbers( "numbers.doc", ios::in); 

   if(!numbers)
   {
      cerr << endl << "File could not be opened" << endl;
      system("pause");
      exit(1);
   }

   for (int i=0, i<10000, i++)
      array[i] = 0; //initializes array

   for (i=0, i<50, i++)
   {
      if (i==1)
         array[n] += array[i];  //What have you done with n?
      cout << array[i];
   //} //I don't think you meant this
   //{ //or this
      if (i==2)
         array[n] += array[i];
      cout << array[i];
   } 

   results.close();

   return 0;
}

Sorry to post again, but I must say you're going about this the wrong way.

For example: you haven't actually used the input file.

Code:

main()
{
   //ifstream stuff...
   //error checking stuff....

   //now. Create some data structure to hold your numbers and read in the data.
   //It'd be nice if the standard library had some container that could associate
   //one number with another. Oh dip.
   //std::map<int,unsigned int> modes;
   //Now, depending on how the file is layed out, you'll have to read stuff in with
   //either >>, getline(), or read()

   //Now you have your data. Read up on std::map and you'll see how short and easy-
   //to-read your program will be.

   return 0;
