An ode to Dennis Ritchie

An ode to Dennis Ritchie, of C and Unix fame, who died this week. A Unix command that echos the input characters and swaps the foreground and background colors after every 7th line break

#include <stdlib.h>
#include <stdio.h>
void main() {
  int l = 0;
  int c = 0;
  char** f = malloc(sizeof (char*) * 2);
  f[0] = "\033[0;7m";
  f[1] = "\033[7;0m";
  while ( ( c = getchar() ) != EOF ) {
    if ( c == '\n' ) {
      if ( l % 7 == 0 ) {
        printf(f[l%2]);
      }
      l++;
    }
    putchar(c);
  }
  printf("\033[0m");
}

Unfortunately, with all candor, I am glad I don't code in C anymore.
