#include<stdio.h>
#define B "booboo"
#define X 10
int main(void)
{
    int age;
    int xp;
    char name[40];
    printf("Please enter your first name.");
    scanf_s("%s", name, 40);
    printf("All right ,%s,what's your age?",name);

      scanf_s("%d",& age);
    xp = age + X;
    printf("That's a %s! You must be at least %d.\n", B, xp);
    return 0;
}

第二个scanf_s怎么不运行了？刚试了%d 前面加了一个空格也不能纠正。大神求解答。
