Thread: Read in a text-file

Hello,
I use MS-VisualStudio 2015.
I want to read in a text-file to bring it out with another format.
But there is no text at the screen?
Here is the code:

insert

Code:

#include<stdio.h>
#include<stdlib.h>
#include<share.h>
#include"stdafx.h"
 
int main(void)
{
    FILE *stream
    char s[12];
    char c;
        if (fopen_s(&stream, "NetWorkNeu1.txt", "r") != 0)
        printf("The file fscanf.out was not opened\n");
    else
    {        
        fscanf_s(stream, "%c", &c);
        fscanf_s(stream, "%s", s);
   
        printf("%s\n", s);
        printf("%c\n", c);    

         fprintf_s(stream,"%s\n", s);        fprintf_s(stream,"%c\n", &c);            

fclose(stream);
    }

    return 0;
}

The main difference between the more secure functions (that have the _s suffix) and the other versions is that the more secure functions require the size in characters of each c, C, s, S, and [ type field to be passed as an argument immediately following the variable.

You don't have such in your code.

....would you please give me an example?

    else
    {        
        fscanf_s(stream, "%c", &c, 1); //read one character

        printf(" %c", c);


        fclose(stream);
    }

    return 0;
}

There you go.
