program to reverse a string using pointer. Pass pointer to function.

using codeblocks
-----------------------------------------------------------------------------------------------------
//program to find reverse of string using pointer passed to function// program title
#include <stdio.h>                   //header file
#include <string.h>                   // header file to handle string
void string_length(char []);    // function prototype with character array
int main()
{
    char string[50];            // character string
    puts("enter string\n");
    gets(string);              //gets string
    string_length(string);     //calling of function with string as parameter
                               // here, string is passed  as reference to formal parameter
    return 0;
}
void string_length(char *strings)// this accepts string with address
{
     strrev(strings);        // supplies length
     puts(strings);          //displays string
}
//note: we can also use char string[] with void string_length in body line. It works.
//once you try.It runs.
//but we can not pass string as pointer in prototype.
// i.e. void string_length(char *[]);
