    reverse an array

    Hi
    So I want to reverse text. If I use the EOF marker, it compiles but does not output.' /n' suffices, but my input could be greater than one line.
    Code:
    #include <stdio.h>
    #define MAX 500
    
    int main()
    {
       char c, phrase[MAX];
       int i;
       printf("enter your phrase?\n");
       for(i=0;(c = getchar()) !='\n'; ++i)
          phrase[i] = c;
       for (--i; i >=0; --i)
       putchar(phrase[i]);
       putchar('\n');
    
       return 0;
    }

    Since getchar() returns an int, and EOF is an int, c should be an int.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
