Solution in C (Clang 3.8.0) (judge verdict: Wrong Answer)

#include<stdio.h>
 
int main(void){
 char c[15];
  scanf("%s",c[15]);
if((c[0]>=3)||((c[0]==2)&&(c[1]>=1))||((c[0]==2)&&(c[1]==0)&&(c[2]>=2))||((c[0]==2)&&(c[1]==0)&&(c[2]==1)&&(c[3]==9)&&(c[6]>=0))||((c[0]==2)&&(c[1]==0)&&(c[2]==1)&&(c[3]==9)&&(c[6]==0)&&(c[7]>=5))){
  printf("TBD");
}
  else{
    printf("Heisei");
  }
  
  return 0;
}
