Euler 19 Sortie

Question

Ceci est pour le projet Euler 19. J'ai à peu près figuré le code, mais ma sortie est +1 pour une raison quelconque.

#include <stdio.h> 

#define SIZE 12 

    int main(void) 
    { 
      int year; 
      int month; 
      int daysinmonths[SIZE] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}; 
      int currentday = 365; /* Account for 1900 */ 
      int sundaycount = 0; 

     for (year = 1901; year <= 2000; year++) { 
       if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) { 
         daysinmonths[1] = 29; 
       } 
       for (month = 0; month < SIZE; month++) { 
         if (currentday % 7 == 0) 
           sundaycount++; 
         currentday += daysinmonths[month]; 
       } 
     } 
     printf("%d Sundays as the first of a month from 1901 to 2000 \n", sundaycount); 
    }

#include <stdio.h> 

#define SIZE 12 

    int main(void) 
    { 
      int year; 
      int month;

      int currentday = 366; /* Account for 1900 */ 
      int sundaycount = 0; 

     for (year = 1901; year <= 2000; year++) { 
       if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) { 
         daysinmonths[1] = 29; 
       } 
       else{ 
        daysinmonths[1] = 28; 
       } 
       for (month = 0; month < SIZE; month++) { 
         if (currentday % 7 == 0){ 
           sundaycount++; 
         } 
         currentday += daysinmonths[month]; 
       } 
     } 
     printf("%d Sundays as the first of a month from 1901 to 2000 \n", sundaycount); 
    }
