check50不能正常工作

Question

check50給人怪異的輸出，請幫助

#include <cs50.h> 
#include <stdio.h> 
#include <math.h> 
int main(void) 
{ 
    int amount,n25,n10,n5,n1,total; 
    int rem; 
    float gamount; 
    printf("O hai!"); 
do{ 
    printf("How much change is owed?\n"); 
    gamount = GetFloat(); 
}while(gamount<0); 
    amount = (int) round(gamount *100.00); 
    rem = round(amount); 
    n25 =(int) rem /25; 
    rem = rem %25; 
    n10 = rem /10; 
    rem = rem%10; 
    n5 = rem /5; 
    rem = rem%5;  
    n1 = rem /1; 
    rem = rem%1; 
    total = n25+n10+n5+n1; 
    printf("%d",total); 
    return 0; 
}

我試圖改變的printf（ 「％d」，總計）聲明的printf（總），但它導致編譯錯誤 編譯使用 鐺-ggdb3 -O0 -std = C11 -Wall -Werror -Wshadow greedy.c -lcs50 -lm -o貪婪

代替此： printf("%d",total); 請使用以下方式試用： printf("%d\n",total);
