Casting

[PrograMan]

How do you cast an integer into a char array and vice versa?

I wonder why everyone's asking this for the last few days?? It ahs been answered in most of the other C/C++ forums. The easiest way is to use sprintf and atoi...

#include<stdio.h>
#include<stdlib.h>

int main()
{
char array[] = &quot;1234&quot;;
int num = 4321;

sprintf(array, &quot;%d&quot;, num); /* int to char array */
num = 0;
num = atoi(array); /* char to int */

return 0;
}
Ankan.

Please do correct me if I am wrong. s-)

Um, that's a nice bit of code there, but I was talking about C++, not C.

*ouch*

The functions you are looking for are _itoa() and atoi().
BTW: This is no &quot;cast&quot; but a &quot;conversion&quot;.

If you knew.... why'd you ask?

C++ can do all that C can do (plus more)

Sorry, didn't mean to sound like that. I was frustrated at the time.

BTW: is there a header that I would need to #include in the code to do the _itoa() and _atoi()?

 

[PrograMan]

Heh, never mind. My bad for the stupid question.

&quot;C++ can do all that C can do (plus more)&quot; Exactly.

Morever, there can be many ways to do the same thing. And you are welcome not to use any code you don't like.

Never mind. (-: (-:

Its <stdlib.h> Ankan.

Any body knows of any function in C++ that is equivalent to atoi in C?

 

[Zyrenthian]

atoi exists in C++
