Thread: What am I doing wrong? Please help

Heres the problem i have: Write a program that reads in a line of input and then prints the line out in reverse order. Recall that you can use scanf() with the %c specifier to read one character at a time from input and that the newline character (\n) is generated when you press the Enter key.

this is the code i have but it doesnt work. what am i doin wrong. Any help would be greatly appreciated.

Code:

#include <stdio.h>
#include <string.h>
int main(void)
{
     char ch[255];
     int index, n, i;

     for (index = 0; ch[index] != '\n'; index++)
     {
            scanf("%c", &ch[index]);

     }

     n = strlen(ch);

     for (i = n - 1; i >= 0; i--)
     {
            printf("%c", ch[i]);
     }

     system ("pause");

     return 0;
}
