C modulos and Remainders

Question

嘿，我有最困難的時間搞清楚如何顯示這個結果。舉例來說，我輸入一個數字，例如59.基於該數字，我會得到1周（s）2天和5小時的剩餘結果。這當然假定一週有40個小時，1天有7個小時才能得到這個輸出。任何幫助正確的方向將是有益的。到目前爲止，我已經設定，就像這樣：

scanf("%d %d %d", &totalWeeksWorked, &totalDaysWorked, &totalHoursWorked); 

Answer 1

#include <stdio.h> 

int const HOURS_PER_WEEK = 40; 
int const HOURS_PER_DAY = 7; 

int main() { 
    int total_hours = 59; // this is the input you get 

    int remaining = total_hours; // 'remaining' is scratch space 

    int weeks = remaining/HOURS_PER_WEEK; 
    remaining %= HOURS_PER_WEEK; 

    int days = remaining/HOURS_PER_DAY; 
    remaining %= HOURS_PER_DAY; 

    int hours = remaining; 

    printf("%d hours = %d weeks, %d days, %d hours\n", 
     total_hours, weeks, days, hours); 

    return 0; 
} 

Answer 2

這不是最快的方法，但也許是最能說明問題：

int numodweeks = input/(7*24); 
int numofdays =input/24; 
int numofhours = 24 - (input/24); 

使用模：

 int numofweeks = input/(7*24); 
     int numofdays = (input%numofweeks)/7; 
     int numofhours = (input%(numofdays*24)); 

然後向他們展示你想要的。
