First, find the position of \0 in the string, and it will be the size of the string. Now run a for loop from (size-1) to 0 and copy the char at the index in a temp array of chars. That's it

You are having four options to write the program. 1. you can make your own reverse function by use of swap. 2. you can use built in reverse function 3. you can write your own reverse function using strlen() 4. using pointer and array if string is constant string
