何时在scanf使用＆

#include <stdio.h>

int main(void){
    int age;
    float assets;
    char pet[30];        // string

    printf(Enter your age, assets, and favorite pet.\n);
    scanf(%d %f, &age, &assets); // use the & here
    scanf(%s, pet);              // no & for char array
    printf(%d $%.2f %s\n, age, assets, pet);

    return 0;
}
