Question

check50给出奇怪的输出请帮忙

#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;
}

check50输出：

我尝试将printf（“％d”，total）语句更改为printf（total）但是会导致编译错误编译使用 clang -ggdb3 -O0 -std = c11 -Wall -Werror -Wshadow greedy.c -lcs50 -lm -o greedy

Answer 1

而不是： printf("%d",total); 试着用这个： printf("%d\n",total);

check50无法正常工作
