Beginner, Help with conversion file.

[johnncc]

Hi.
I have this program that is supposed to take a tab delim file and create a fixed length. When I comppile this code it gives an error: E:\dialer_conversion.cpp(35) : error C2664: 'fgets' : cannot convert parameter 3 from 'char *' to 'struct _iobuf *' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast.

I can't figure this out. Any help will be appreciated. If there is some material I can read on this or if someone knows a fix anything will help. Code below.

// this program will open a tab file and save as fixed length
#include <stdio.h>




int main()

{


	// set file pointers
	FILE *dialPtr;
	FILE *smartPtr;

     // input tab file name
	char *myFile;
	
	//input file to convert
	printf("Enter the file to convert: (dialer.txt).\n> ");
	scanf("%s", myFile);

	//check if files are open
	if (((dialPtr = fopen (myFile, "r")) = NULL) && ((smartPtr = fopen ("smartout.txt", "w")) = NULL))
	
	//if not open
	{
		printf("Unable to open file.\n");
	}
	else{

		//process files
		char line[4096];

		

		while (fgets(line, sizeof(line), myFile))
		{
			char *rec;
			char *clNum;
			char *clName;
			int acct;
			char *dbtr;
			char *addy;
			int phone;
			char *pt;
			int assign;
			char *stat;
			char *desk;
			int tot;
			int lstPay;
			int lstWork;
			char *state=line;//buffer

			//extract info from buffer
			rec = "REC00004A1";
			clNum = strsep(&state, "\t");
			clName = strsep(&state, "\t");
			acct = atoi(strsep(&state, "\t"));
			dbtr = strsep(&state, "\t");
			addy = strsep(&state, "\t");
			phone = atoi(strsep(&state, "\t"));
			pt = strsep(&state, "\t");
			assign = atoi(strsep(&state, "\t"));
			stat = strsep(&state, "\t");
			desk = strsep(&state, "\t");
			tot = atoi(strsep(&state, "\t"));
			lstPay = atoi(strsep(&state, "\t"));
			lstWork = atoi(strsep(&state, "\t\r\n"));

			//send to file
			fprintf(smartPtr, "%-10s%-10s%-30s%-10d%-10d%-30s%-25s%-10d%-30s%-6d%3s%-5s%5d%-8d%14d%-6d\n", rec, clNum, clName, phone, account, dbtr, addy, phone, pt, assign, stat, desk, tot, tot, lstPay, lstWork);
		}
	
		//close files
		fclose(smartPtr);
		fclose(dialPtr);
	}

	//success
	return 0;
}

while (fgets(line, sizeof(line), [red]myFile[/red]))

Since the 3rd parameter is supposed to be a [tt]FILE*[/tt], I would assume that you instead meant this.

while (fgets(line, sizeof(line), [blue]dialPtr[/blue]))

Of course, first you should allocate some memory into which to receive the filename rather than just leaving it dangle:

char *myFile;

Perhaps change it to this:

char myFile[128];

Also, [tt]#include <stdlib.h>[/tt] since you are using stuff from it, and [tt]#include[/tt] whatever header declares [tt]strsep[/tt]. And watch out here:

if ( ((dialPtr = fopen (myFile, "r")) [red]=[/red] NULL) && ((smartPtr = fopen ("smartout.txt", "w")) [red]=[/red] NULL) )

A comparison is [tt]==[/tt] and an assignment is [tt]=[/tt].
