Thread: C++ programming question

I am tring to read contents from a file and pass it into array. Then take that array and put it into another array. Next read those values back out to an oupt stream. My code is below. However, I am getting subscript errors. What is wrong? Also, my input file contains float values.

Code:

int main ()
{
	//Declare Variables
	ifstream inFile;  //input stream
               ofstream outFile; //Output stream

	 
     int increm=0;    //index for input stream
	      float array[5];
	      inFile.open("test.txt");
	     outFile.open("tester.txt");
	   while (!inFile.eof())
                 {     
                                inFile >> array[increm];	          //Read contents of file 
		 cout<<array[increm];
          for(int temp= 0; temp <= array[increm];temp++) of    
	for(int i=0; i= temp; i++)
	{	 
		array[increm] =temp[i];
		 cout<< temp[i];	
                                outFile>>	tester.txt;		      				
	}								      	
	       increm++;                           //increment index	   
      }	  
     inFile.close();//close output stream
     outFile.close();

You need to format your code properly. The way it is, many people won't even read it.

Very strange code to me.

- Don't use eof, it's bad

Code:

for(int temp= 0; temp <= array[increm];temp++) of

- What's this?

Code:

array[increm] =temp[i];

- You store an float into an int, think about what happens? Secondly, an int doesn't have an index []. Temp only exists within the scope of your first for loop.

Code:

outFile>>	tester.txt;

- What is this supposed to do? Outfile is an ostream so you must use << instead of >>, is tester.txt a variable? No it's a filename what are you trying to do?

- Is this your entire code? If it is, you have forgotten some things. You should read the tutorials on this (or another) website / book.

Keep trying!
