casting the value of a string into int

[keak]

Hi there; please bare with me as I think this is a really basic question; googled without much help.

how would I cast the "value" of the string into int ?

I have:

char word[20]; // and this variable contains say "hello world"

and I tried the following
int word_int = atoi (word);
int word_int = (int) word;
int word_int = (int) &word;

but not of them seem to be giving the correct result ....

You don't cast a string into an [tt]int[/tt]. What value would you expect "hello world" to be?

Given your attempts, I might grudgingly suggest this.

#include <stdio.h>

int main(void)
{
   char text[] = "hello world";
   int value = *(int*)text;
   printf("value = %d\n", value);
   return 0;
}

/* my output
value = 1819043176
*/

It's a while since i programmed in C but I seem to remember that you need to declare:

int atoi();

and then

char a[10];
int i;

strcpy(a, "27");
i = atoi(a);


hope that helps.
