realloc ()

[Max]

I am trying to to read lines from a file

I want to print it using malloc, ....I don't know how long is the text in the file so I want then to increase storage by using realloc()

#include <stdio.h>
#include <string.h>

int main (void)
{
	FILE *fptr;

	char fileline;
	char line;

	fptr=fopen("c:\\c\\file.txt","r");

	line=(char*)malloc(50);

	if(fptr!=0)
	{
		while (!feof(fptr))
			{
            fgets(fileline+strlen(line),50,fptr);
           	}
	}
	else
		{
		perror("\nError Opening File.\n");
		}
	strcpy(line,fptr);
	puts(line);

	fclose(fptr);
	free(fileline);
	

return 0;
}

>>line=(char*)malloc(50);
The cast isn't necessary, but you've forgotten to include stdlib.h which has malloc's prototype in it.

>>while (!feof(fptr))
Don't use feof() in this manner, its wrong and will give you unexpected results. Search the board for more information.

>>fgets(fileline+strlen(line),50,fptr);
Ohhh... nasty! fileline is a char (a single character) and line is new memory, therefore strlen() won't give you want you want.

>>I want to print it using malloc,
Clarify please... malloc isn't for printing. What's the purpose of the program?
