is there in the book c kernighan and Ritchie

Is it? I had no idea. Thanks.

I got mine from the book C How to Program - Deitel

/* This string reversal might be faster and more efficient -- uses minimal memory great for embedded systems BY: STEVE KING Tucson Arizona */ void reverse( char *ptr ) { char saved_char; // need to save off a character char *saved_ptr; // need to save off original ptr address saved_ptr = ptr; // save the actual ptr address // I only need to go through half the string to swap positions // so when the ratio of savedADDRESS to incrementedADDRESS is 2, then we quit while(strlen(saved_ptr)/strlen(ptr) != 2) { saved_char = *(saved_ptr+strlen(ptr)-1); // save off a char *(saved_ptr+strlen(ptr)-1) = *ptr; // swap chars *ptr = saved_char; // swap chars ptr++; // increment to next address } ptr = saved_ptr; // need to return the ptr address to original }

Here's a nice one

void reverse( char *ptr ) { /* STEVE KING TUCSON ARIZONA */ char saved_char; // need to save off a character char *saved_ptr; // need to save off original ptr address saved_ptr = ptr; // save the actual ptr address // I only need to go through half the string to swap positions // so when the ratio of savedADDRESS to incrementedADDRESS is 2, then we quit while(strlen(saved_ptr)/strlen(ptr) != 2) { saved_char = *(saved_ptr+strlen(ptr)-1); // save off a char *(saved_ptr+strlen(ptr)-1) = *ptr; // swap chars *ptr = saved_char; // swap chars ptr++; // increment to next address } ptr = saved_ptr; // need to return the ptr address to original }

I enjoyed the recursive "reverse" string printing function. I tried the following recursive "forward" string printing function, but had errors? Could anybody tell me why and provide a function that works? void ret_str(char* s) { if(*s) cout

#include void ret_str(char* s) { if(*s) cout
