hi

i am trying to read a file and save to array

i wrote one and it worked accept it not reading ot line by line, so i wrote another one but i am trying to make it as function
when i make function call i get this error

read.c:32:13: error: invalid operands to binary * (have ‘char *’ and ‘char *’)

the function should take char* so whats the problem ?

my code

#include <stdio.h>


Nstring *readLine(FILE *file)
{
    char buffer[1000];
char * Nstring ;
char *line ;


    numstring *result = [ numstring  strc:256];


    int chars;
    do
    {
        if(fscanf(file, "%4095[^\n]%n%*c", buffer, &chars) == 1)
            [res = appendFormat:@"%s", buffer];
        else
            break;
    } while(chars == 1000);

    return res;
}
int main (){
char * Nstring ;
char *line ;
FILE *file = fopen("myfile", "r");
// check for NULL
while(!feof(file))
{
    Nstring *line = readLine(file);

}
fclose(file);
return 0 ;
}

It looks like you're mixing standard C and Objective-C. Note that this is the C forum, did you mean to post in the Objective-C forum?

** yes ...i am mixing between them ...i dont know the Objective C ...i am learning how to program with C not Objective C ..but i use what i see on the internet and combine it to make specific code ... so definitely i am mixing between them now !

That's a problem because your code will not compile as C, and if you ask questions in the C forum, the first thing you'll be told is one of the following (depending on how helpful and familiar with Objective-C the person is):

  1. Your code is not C and is wrong.
  2. Your code is Objective-C and you're in the wrong place.

If you want to learn C, learn C, not some bastardization of C and Objective-C that may not compile as either.

You need headers like

  1. <math.h>
  2. <stdlib.h>
  3. <curses.h> or if you are using microsoft <conio.h>
  4. <stdfx.h>
  5. <graphics.h>

etc

If you don't know what you're talking about, please don't pretend that you do. Because those of us that know what we're talking about will see through it easily.

ok ,,, i was just asking ,, i am sorry i will write another one with C not Objective C cuz i dont deal with it ,, i thought it was C

thanks for the information though
