c - 错误:Array subscript is not an integer

Question

int menu(int code)
{
    char item[7][30]={"Lunch/Dinner Set ","Breakfast Set","Kiddies Set",
                      "Promotion","Drink","French Fries","Dessert"};    
    int code_menu[7]={1,2,3,4,5,6,7};
    float price[7]={8.00,5.00,6.00,3.00,2.00,3.00,3.50};    
    int cnt;
    printf("\n\tCode\t\tItem\t\t\tPrice\n\n");

    for(cnt=0; cnt<5; cnt++) 
    {
     printf("\t%d\t\t%s\t\t\tRM%.2f\n", code_menu[cnt], menu[cnt], price[cnt]); 
    } 
}

谁能解释一下我在这行代码中做错了什么？

printf("\t%d\t\t%s\t\t\tRM%.2f\n", code_menu[cnt], menu[cnt],price[cnt]);   

Answer 1

我怀疑，你的意思是:

printf("\t%d\t\t%s\t\t\tRM%.2f\n", code_menu[cnt], item[cnt], price[cnt]);
