c - 我认为我没有正确使用指针。 C

Question

所以我已经尝试做这个作业几个小时了，但我无法弄清楚，我 99% 确定这与我使用指针的方式有关。我得到的错误是中断 0xC0000005:访问冲突写入位置 0xCCCCCCCC。我认为这意味着我的一些指针为空。提前为业余代码道歉..

#include<stdio.h>

void load(int *salary)
{
    printf("Please enter your salary: ");
    scanf("%d", *salary);
}

void calc(int *salary, float *rate, int *raise, int *newsalary)
{
    rateofsalary(&salary);
    *raise = *salary/(*rate);
    *newsalary = *raise+*salary;
}
float rateofsalary(int *salary)
{
    float rate;
    if(*salary<0 && *salary>=30000)
        rate = 7.0;
    else 
        if(*salary<30000 && *salary>=40000)
            rate = 5.5;
        else 
            if(*salary<40000)
                rate = 4.0;
    return rate;
}

void print(int *salary, float *rate, int *raise, int *newsalary)
{
    printf("|     | Salary | Rate % | Raise | New Salary |\n");
    printf("|     | %d     | %0.2f  | %d    | %d         |\n", salary, rate, raise, newsalary);
}

void main()
{
    int salary, raise, newsalary;
    float rate;
    load(&salary);
    rateofsalary(&salary);
    calc(&salary, &rate, &raise, &newsalary);
    print(&salary, &rate, &raise, &newsalary);
}

Answer 1

scanf("%d", *salary);

改成

scanf("%d", salary);

printf 函数应该是

printf("|     | %d     | %0.2f  | %d    | %d         |\n", *salary, *rate, *raise, *newsalary);
