谁能告诉我错误在哪里？

Question

当程序运行时，在它中间（在输入疫苗名称后）它会停止并给我 {Exception Thrown} 谁能帮我解决这个问题？我还附上了它给我的错误照片

 #include <stdio.h>

    #include <stdlib.h>
    int main()

        int choose, dosage, quantity;

            scanf_s("\n%d", &choose);
            if (choose == 1)
            {
                char ch;
                FILE* cv;
                errno_t err;
                err = fopen_s(&cv, "vaccine.txt", "w");
                for (int i = 0; i < 5; i++)
                {
                    printf("Please Enter Vaccine Full information %d \n", i + 1);
                    printf(" Name of Vaccine : ");
                    scanf_s("\n%s", &name);
                    printf("Please Enter Vaccine Code %c \n", i + 1);
                    printf(" Vaccine Code : ");
                    scanf_s("\n%s", &code);
                    printf("Please Enter Vaccine Producing Country %c \n", i + 1);
                    printf("Producing Country : ");
                    scanf_s("\n%s", &produce);
                    printf("Please Enter Dosage Required %d \n", i + 1);
                    printf("Dosage Required (MAX=2 - MIN=1) : ");
                    scanf_s("\n%d", &dosage);
                    printf("Please Enter Population Covered %d \n", i + 1);
                    printf("Population Covered (%) : ");
                    scanf_s("\n%f", &population);
                    printf("Please Enter Vaccine Quantity %d \n", i + 1);
                    scanf_s("\n%d", &quantity);
    
                    fprintf("%s %s %s %d %f %d", name, code, produce, dosage, population, quantity);
                }
            }
            
        }
        return 0;

}

Answer 1

线

fprintf("%s %s %s %d %f %d", name, code, produce, dosage, population, quantity);

错了。您必须将文件指针作为 fprintf() 的第一个参数传递。应该是：

fprintf(cv, "%s %s %s %d %f %d", name, code, produce, dosage, population, quantity);

还有

• 您应该在继续下一个操作之前检查 fopen_s 是否成功，如果失败则停止操作。
• 您应该删除 & 中使用的数组名称（code、name、produce）之前的 scanf_s。表达式中的数组（不包括一些例外）会自动转换为指向第一个元素的指针，因此此处不需要显式 &。它还会使类型错误 scanf() 期望 char* 为 %s，但诸如 &code 之类的东西是指向数组的指针（如 char(*)[10]）。
