我正在尝试制作一个简单的咖啡店经理，我使用了一个2D字符串数组来创建一个菜单，用户可以编辑它，但是每次我试图替换一个字符串，当我试图打印它时，数组的其余部分就会消失。
我知道这是基本的东西，我的代码可能有很多问题，但我真的不知道为什么它不工作。
代码：

using namespace std;
    string menu[8][3] = {
        {"\n Expresso", "-------------", "$6.50"},
        {"\n Latte", "----------------", "$8.00"},
        {"\n Cappuccino", "-----------", "$8.00"},
        {"\n Chocolate", "------------", "$9.50"},
        {"\n Croque_Monsieur", "------", "$18.50"},
        {"\n Panettone", "------------", "$12.99"},
        {"\n Pao_de_Queijo", "--------", "$4.99"},
        {"\n Petit_Gateau", "---------", "$18.99"},
    };

    void editMenu(){        
        int i, op, count1, count2;
    
        printf("\n1. Edit Menu");
        printf("\n2. Back");
        printf("\n");
        scanf("%d",&op);
        

        switch(op){

//asks user to chose a line and edit the first (product) and third (price) columns          
            case 1:
                while(op==1){
                   system("cls");

                                
                    printf("Which line would you like to edit?\n");
                    scanf("%d", &i);
                    
                    printf("\nInsert new product: ");
                    scanf("%s", &menu[i][1]);
                
                    printf("\nInsert new price: ");
                    scanf("%s", &menu[i][3]);
                    
                    system("cls");

//loop for printing the menu            
                    for(count1 = 0; count1<8; count1++){
                        for(count2 = 0; count2<3; count2++){
                            cout << menu[count1][count2];
                        }
                     }
            printf("\nPress 1 to make more changes or other key to exit :");
            scanf("%d", &op);
            } 
//End of while
            break;
                
//Exit
            case 2:
                system("cls");
                home();
            break;
        }
    }
