在 CS50 中执行 Pset1,我完全不明白为什么我的代码不起作用。出现语法错误
cash.c:6:1: error: expected identifier or '('
最佳答案
看起来您将一个函数放入另一个函数中。我无权访问头文件,但我认为您需要的更像是以下内容。
#include <stdio.h>
#include <cs50.h>
#include <math.h>
int main(void) {
float dollars;
// prompt user for "0.00" value
do {
dollars = get_float("Change owed: ");
} while (dollars <= 0);
// print amount of coins used for change
printf("%f\n",get_change(dollars));
return 0;
}
int get_change(float dollars) {
//calculate which coins will be used
int cents = round(dollars * 100);
int coins = 0;
int denom[] = {25, 10, 5, 1};
for (int i = 0; i < 4; i++);
{
coins += cents / denom[i];
cents = cents % denom[i];
}
return coins;
}
