Question

程序没有显示错误，但无法编译。您能帮我解决这个问题吗？

int main(void) {
    printf("\n*************************************************************\n");
    printf("\n*************************************************************\n");
    printf("\n******** Program find the solution to which car you *********\n"); 
    printf("\n******* could still earn if you received A's for the ********\n"); 
    printf("\n********* remainder of your undergraduate classes. **********\n");
    printf("\n*************************************************************\n");
    printf("\n*************************************************************\n");
    printf("\n  You will be asked to enter your current GPA with at most 3 \n");
    printf("\n  Decimal places and the number of credit hours that the GPA \n");
    printf("\n       Was based on, which should be a positive number.      \n");
    printf("\n  And the honors you qualify for will be displayed to screen.\n");
    printf("\n*************************************************************\n");
    printf("\n*************************************************************\n");

    printf("\nPlease enter your current GPA with at most 3 decimal places.\n");
    printf("\nFor example, for a GPA of 2.3333333333, enter 2.333\n");
    printf("\nThis GPA should fall between 0 and 4.0 --> ");
    scanf("%d, &numb1\n");
    printf("\n*************************************************************\n");

    printf("\nPlease enter the number of credit hours that this GPA was based");
    printf("\n on. This should be a positive integer\n");
    printf("\nFor example, for twelve credit hours, simple enter 12.\n");
    printf("\n-->");
    scanf("%d, &numb2");
    printf("***************************************************************\n");
}

Answer 1

由于双引号的放置位置，您将向 scanf 传递一个参数。

应该是:scanf("%f", &numb1); 和 scanf("%d", &numb2);

请注意，numb1 是 %f，因为它是 float ，numb2 是 %d(对于整数)。

此外，您从未声明过变量 numb1 或 numb2，因此您还需要: float numb1; int numb2; 位于函数顶部。
