files revisited

[Hyena]

i'm just beginning files, and am in need of help. program makeword (below) simply saves an inputted word to a file. readword should read this file and print out the word, but it doesn't work. help. i already posted this once, and added the suggested changes, but it didn't make any difference. help.



//program makeword- makes a word and stores it in a file

#include <stdio.h>
#include <iostream.h>

void main()
{
FILE *fPtr;


fPtr = fopen("a:\\word.dat", "w");

char *word = new char[30];

cout << "Enter a word: ";
scanf("%s",word);
fprintf(fPtr, "%s", word);


fclose(fPtr);
}

//============================================================//



//program readword- reads data from makeword
#include <iostream.h>
#include <stdio.h>

void main()
{
FILE *fPtr;
char *word = new char[30];

if((fPtr = fopen("a:\\words.dat","r")) != NULL)
{
fscanf(fPtr,"%s", word);
printf("%s",word);

fclose(fPtr);
}
else { cout << "could not be opened."; }

}

Could it be that you are writing your word to word.dat and trying to read it from words.dat??

Besides the fact (as mentioned earlier) that the two files are named differently, your program will have memory leaks as shown -- remember to delete any memory allocated with new before the pointer variable goes out of scope.

#include <stdio.h>
#include <iostream.h>
void main()
{
char *szFile="dummy.dat";
FILE *fPtr;
fPtr = fopen(szFile, "w");
char *word = new char[30];
cout << "Enter a word: ";
scanf("%s",word);
fprintf(fPtr, "%s", word);
fclose(fPtr);

if((fPtr = fopen(szFile,"r")) != NULL)
{
fscanf(fPtr,"%s", word);
printf("\nREAD STUFF WAS:%s",word);
fclose(fPtr);
}
else
{
cout << "could not be opened.";
}

delete word;

}




I hust had to make sure the problem had to be that simple and it was
