what is wrong with this code? cant figure it out.

[README]

//what i needed to do was to read the file number.txt, and check for frequencies by using arrays.

#include<iostream>
#include<fstream>
#include<ctime>
#include<cstdlib>
using namespace std;
int MAX=20;//Global variable
void createDataFile();//Function prototype
int main(){
 
//Call function;
createDataFile();
 
//Declare Variables
int a(0);
int read;
 
ifstream dataFile("numbers.txt");//open stream
if(dataFile.fail())        //check if stream failed to open
        cout<<"In fail state"<<endl;
//Create array
int freq_array[20]={0};
for(int i=MAX-1; i>=0; i--)
   cout << i << ": " << freq_array[i] << endl;
 
dataFile.get(read);
 
 
}
 
/*
This function generates a file called numbers.txt with random
numbers from 0-MAX
*/
void createDataFile(){
//dataFile is the file handle for “numbers.txt”
ofstream dataFile("numbers.txt");
//Seed random number generator rand() function
srand(time(0));
//Write 150 random number to the file numbers.txt
for (int i = 0; i<150; i++)
dataFile << (rand() % MAX) <<'\n';
}

What does your code do and what is it supposed to do instead? We aren't psychic,
sorry for that.

oh it justs creates a file called numbers.txt, inserts it with 150 random numbers. then i have to check each number's frequency by using array. for example, a number 3 in the number.txt corresponds to the element in array [2]. and thus array[2] gets x++. and so on

Please tell us what the problem is?
... are you getting compile errors?
... is the program misbehaving?

Whatever is going on, please describe the symptoms.

Did you implement what you just described? For your information: we are not
going to do it for you.

Are you getting a compilation error, or just unexpected program behaviour? At first glance, I see to the output of the "get" iostream method as an integer type. If you read a reference for get(), you'll see that the expected variable type should be "char".
