I'm sorry, but your code contains several errors.

First, you need to declare the `main` function as `int main(void)` instead of just `main(int)`.

Second, when you are reading in the user's name with `scanf`, you should use `%c` instead of `%s` since you are only reading in one character at a time.

Third, when you are reading in the user's age with `scanf`, you should use `%d` instead of `%f` since age is an integer.

Fourth, you have not properly defined `B` in your code.

Finally, the line `Xp=age +X` should be `int xp = age + X;`.

Here is the corrected code:

#include <stdio.h>

#define B "mistake"
#define X 10

int main(void) {
    int age;
    char name;

    printf("Please enter your first name: ");
    scanf("%c", &name);

    printf("All right, %c, what's your age?\n", name);
    scanf("%d", &age);

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

    return 0;
}
