Problem in name reverser

but why would i swap it if i ill only switch from buffer[i]=buffer[x] ??

Because without a temporary variable, what you have currently happens. Watch:

Code:

---

cow
[c] = [w]
wow
[w] = [w]
wow

---

Oops. Since you overwrote the C, you can't move it over to the W.


Quzah.

yah thanks alot man i understand it now and i did it

Code:

---

#include <stdio.h>
#include <string.h>
void reverse_it(char *buffer,int length)
{
    int i,x;
    char saver;
    for(i=0,x=length-1;i<x;i++,x--){
        saver=buffer[i];
        buffer[i]=buffer[x];
        buffer[x]=saver;
        }
}
int main(void)
{
    char name[]="NAME";
    int i;
    reverse_it(name,strlen(name));
    puts(name);
    getchar();
    return 0;
}
