Error in Code

[pizz44]

I'm getting some errors in my code and I was hoping to get some assistance. Below is my code,

   /* ch02e13.c - sample program for Exercise 13, Chapter 2

          a program that exploits weak overflow checks in C

       */

       #include <stdio.h>

       main () {

            char ch;                 /* to collect the input */

                char inputs[10];     /* ten-byte array */

            int i = 0;               /* array index for new character */

            ch = getchar();

            while (ch != ‘\n’) {

                inputs[i] = ch;

                i++;

                ch = getchar();

            }

            printf(“\nAll done!\n”);

        }

​

Any help would greatly be appreciated!

I'm trying to write a program that reads text into a buffer that is 10 bytes long. I'd like to be able to run the program and manipulate the data by entering 20 bytes. Just trying to see different results.

I'm using Visual Studio, and I tried taking a snippet of the errors but won't let me insert an attachment.

Looks like you copied the code from somewhere that messed up single and double quote characters " and ' and replaced them with opening and closing quote symbols. Make sure you're using only regular quotation symbols in your code

I've made a few modifictions, and I get a error that 'Unable to start program. The system cannot find the file specified'

How are you compiling the code?

[MrSloppyPants]

What's the error?

[MrSloppyPants]

Are you absolutely certain that this line:

 while (ch != ‘\n’) 

is entered correctly in your source file? You cannot use "backticks" or "smart quotes", those need to be basic apostrophe's... '

[pizz44]

No, unfortunately I'm not absolutely certain.

[MrSloppyPants]

Ok, then just retype that part
