reversion of string in c

Question

In python reversing of string is as easy as:

string[::-1]

But not very same in c. This is the code I am using to reverse integers in C:

#include <stdio.h>

int main(int argc, char *argv[])
{
    int number, right_digit;

    printf("Enter your number.\n");
    scanf("%i", &number);

    do {
        right_digit = number % 10;
        printf("%i", right_digit);
        number = number / 10;
    } while(number != 0);

    printf("\n");
    return 0;
}

The limitations of above program is:

• It does not works on negative integers
• It does not works on strings

The challenge is to reverse a string (not int) in minimum chars.
