adding stuff to the beginning of arrays?

[dubae524]

Let's say I have a char array, okay?

I initialize it:

char gerbil[255] = "mike tyson";

But let's say that, later in the program, I want to add the following string to the beginning of it:

"that stupid ear-biting "

so this would be true:

gerbil == "that stupid ear-biting mike tyson"

any answers?

create a new string:

char hamster[] = "that stupid ear-biting " ;

then concatanate the two:

char hamger[100];

hamger = strcat(hamster, gerbil);

ps - you gotta use <string.h> for this

Oh, thanks!

that won't work.
it will append the content of gerbil to the buffer of hamster (which is too small) and then assign the memory address of hamster to hamger (probably a syntax error). The correct way would be:

// create a new string: 
char hamster[100] = "that stupid ear-biting " ; 
// then concatanate the two: 
strcat(hamster, gerbil);

Now hamster contains the complete string. You must make sure that hamster is large enough to hold both.

yep i was wrong about the assignment but you can definately declare an array dynamically and then still strcat onto it.

yeah, but your code didn't allocate an array dynamically...
