Title: Using multidimensional arrays
Post by: colddax on July 09, 2007, 06:42:53 PM

Hello Everyone.

I have a question regarding the use of multidimensional arrays.

Lets say I have the following code segment

Code: [Select]

char file[1][200];

... and later on I copy something to the file array

Code: [Select]

strcpy(&file[0][0],"Testing 123");

How would I access just the "T" in "Testing"? Accessing &file[0][0] gives me "Testing 123".
Would I need to do something like this &file[0][0][0]?

Thanks for any help you can provide.

You know what, I think I just figured it out. I believe it is file[0][0]. I was just using it incorrectly.

Hello

Here is the correct code:

Code: [Select]

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

void main(void)
{
  char file[1][200];
  strcpy(file[0], "Testing 123");
  printf("%c\n", file[0][0]);  // Display the T
  printf("%s\n", file[0]);  // Display the entire string
}
There is no need to add &
If you want to use it, you have to add [ 0 ] in order to "cancel" the & character.
