c - 用 c 修复百分比计算器？

Question

我尝试使用此代码，但在用户输入总分后控制台崩溃

#include <stdio.h>
#include <string.h>

int main () {
    int part, total;
    int whole = 100;
    printf("What is total score of the exam?\n");
    scanf("%d", part);
    printf("Enter your score on the exam\n");
    scanf("%d", total);
    printf(total/part * whole);
    return 0;
}

简短的回答，这样这个问题就不会悬而未决。您应该启用编译器警告并学会解释它们，这样您就可以更轻松地自己解决问题。在 GCC 上，您可以添加 -Wall 编译器选项来显示查看此类问题所需的常见警告。

#include <stdio.h>
#include <string.h>

int main ()
{
    int part, total;
    int whole = 100;

    printf("What is total score of the exam?\n");
    scanf("%d", &part); /* address of part needed, not its value*/

    printf("Enter your score on the exam\n");
    scanf("%d", &total); /* address of total needed, not its value*/

    printf("%d", total/part * whole); /* printf expects a string as its first parameter */
    return 0;
}
