If the string is held by an array you can access each element progressively from the end in a for loop and place each in a second array starting with its first element.
Another way is to set two pointers, pa* to element [0] and pb* to sizeof -1. Swap the elements being pointed to using a swap() function from the STL and then increment pa++ and decrement pb--. Repeat until reversal complete.
