Thread: Realted to File

I have piece of code which HAS to use the ANSI file functions.

I have a text file which stores 2 values: Address and Data. Its something like :

1 233
48 5.8

I want to extract these values from file and use them.
Here is how my code looks:

Code:

int main()
{
	char * lbuf = new char(8); // To store add n data
	int lreadBytes = 0;
	long lAddress= 0; 
	double lData = 0;
	

	
	FILE *pFile = fopen ("c:\\testprog1.txt","r");
	
	if (pFile != NULL)
	{
		
		do{
			// Read Address
			lreadBytes = fread(lbuf,1 ,4, pFile); // where pfile is file pointer, Read 4 bytes for long
			if(*lbuf == ' '|| *lbuf== '\t' || *lbuf == '\n')
			{
				continue;
			}
			// Convert char * to long
			lAddress= atol(lbuf);
			
			cout<< lAddress;
			
			// Read Data corresponding to Address
			
			lreadBytes = fread(lbuf,1 ,8, pFile);// Read 8 bytes for double
			
			while(lreadBytes!= 0)
			{
				if(*lbuf == ' '|| *lbuf== '\t' || *lbuf == '\n')
				{
					continue;
				}
				// Convert data from char* to double
				lData = atof(lbuf); 
				
				cout<<lData<<std::endl;
				
				break; // Start reading next address		
				
			};
			
		}while(lreadBytes!= 0); // Keep reading till all the bytes are read.
		
	}
	return 0;
}

Assume that long takes 4 bytes and double takes 8 bytes. But this code doesnt work.

Can this code be written in more optimized manner?

besides the cout-ing and whatnot, this seems a lot more C like than C++ like.

>> I have piece of code which HAS to use the ANSI file functions.

sounds like a silly limitation on a homework thing. Streams are much easier to use, so why use the FILE thing?

>> new char(8)

should that be new char[8];?

Thanks for your response.
Actually my application has to use the ANSI functions because my OS does not support streams.

Made the correction char[8]

What OS is this?
If it really didn't support streams than you wouldn't be able to use cout either.
