clearing a variable

hello,

i am writing a program in C. i have it like this so far:

------------------------------------
#include<stdio.h>

char *com[256];

int main()
{
[first half of prog goes here]
[i want to clear the com variable here]
[last half here]

return 0;
}
------------------------------------------

yea, so can anyone tell me how i can clear the variable? cause its currently got the string "echo hello" in it, and i want to put in "echo yes", but it turns out as "echo yeslo" so i figured if i cleared it it wouldn't do that.

thanks all!

> char *com[256];
Given your description, I'm pretty sure you should be using

char com[256];

> but it turns out as "echo yeslo"
Well if you did
strncpy( com, "echo yes", 8 );
that is what you would see

So just do this
strcpy( com, "echo yes" );

And if you wanted to simply blank out the array, this would do the trick:

Code:

---

memset( com, 0, sizeof(com) );

---

Or simply use a for-loop to clear the array or just a part of it, since in both cases there will be "echo " in the string.

thanks alot guys, especially Deckard. i looked up the man page for memset, and it looks like a really cool function, and now my prog works :)

thanks again!
