C 如何比较 2 个 int

Question

我想做一个类似验证码的检查，但它所做的只是崩溃。 代码有什么问题吗？ 我的代码如下所示:

printf("I need to make some tests to ensure that you are a human being.\n");
printf("Let's start\n");

int randomNumber1 = rand() % 100;
int randomNumber2 = rand() % 100;
printf("What is %d + %d ?\n", randomNumber1, randomNumber2);
int randomNumberSum = randomNumber1 + randomNumber2;
int solution;
printf("%d \n", randomNumberSum);
scanf("%d", solution);

if (solution = randomNumberSum) {
    printf("Good job human !\n");

} else {
printf("Nice try, bot \n");
}

Answer 1

当使用scanf()读取整数时，您需要提供int变量的地址:

scanf("%d", &solution);

您还需要在 if 语句中使用 ==(比较)而不是 =(赋值)。
