Thread: Reversing a string

I am supposed to reverse an entered string, I was given the hint that you basically copy the string into another one and then reverse from there but I am not sure how to actually do the reversal. Below is the code I have so far. This succesfully copies the string but im not sure how to reverse, help would be great

Code:

# include <stdio.h>



void strrev (char [], char []);


int main ()
{
    #define lsize 81
    char message[lsize];
    char newmessage [lsize];
    
    printf ("Enter a sentence:  ");
    gets (message);
    
    strrev (newmessage, message);
    
    puts (newmessage);
    
    system ("PAUSE");
    return 0;
}


void strrev (char string1[], char string2[])
{
     int i=0;
     
     while (string2[i] != '\0')
     {
           string1[i]=string2[i];
           i++;
     }
     string1[i]='\0';
     
     
}
