为什么我的数组或函数不起作用？

Question

为什么我的数组（或函数）不起作用？我一直在想这个很久了。我没有收到来自GCC的错误或警告，我想从其中的一张HandCard或playerCard中移出一张卡，但是没有任何可见的结果...最小的可复制示例（我相信它是在mainCenter中编辑的函数'centerCardStack'或数组'move'中）：

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>
char playerName;
int row, col, toStack;
int validityCheck;
int move[4];
int centerCardsOne, centerCardsTwo, centerCardsThree, centerCardsFour, centerCardsFive;
int playerCardsComOne, playerCardsComTwo, playerCardsComThree, playerCardsComFour, playerCardsComFive;
void centerCardStack(int section, int card, int toCenterStack){
    //edit the center stacks from a persons selection
    //and edit the persons handCards or playerCards
    if(playerName == 'P'){ //test who player is, later code is 'P'
        if(section==1){ //test secion. 1 is playercards, 2 is handcards
            if(card==1){ //test card. if card is one, first card...
                if(toCenterStack==1){ //test which stack
                    if(playerCardsComOne-1==centerCardsOne) //test if valid
                        centerCardsOne++;
                    else //or not
                        validityCheck=1;
                }
                if(toCenterStack==2){
                    if(playerCardsComOne-1==centerCardsTwo)
                        centerCardsTwo++;
                    else
                        validityCheck=1;
                }
                if(toCenterStack==3){
                    if(playerCardsComOne-1==centerCardsThree)
                        centerCardsThree++;
                    else
                        validityCheck=1;
                }
                if(toCenterStack==4){
                    if(playerCardsComOne-1==centerCardsFour)
                        centerCardsFour++;
                    else
                        validityCheck=1;
                }
            }
        }
    }
}
void beginCode(){
    srand(time(0));
    playerCardsComOne = (rand() % 12) + 1;
    playerCardsComTwo = (rand() % 12) + 1;
    playerCardsComThree = (rand() % 12) + 1;
    playerCardsComFour = (rand() % 12) + 1;
    playerCardsComFive = (rand() % 12) + 1;
}
//run the above
int main(){
    playerName='P';
    beginCode();
    printf("handcards: %2d|%2d|%2d|%2d|%2d\n", playerCardsComOne, playerCardsComTwo, playerCardsComThree, playerCardsComFour, playerCardsComFive);
    printf("center---: %2d|%2d|%2d|%2d|%2d\n", centerCardsOne, centerCardsTwo, centerCardsThree, centerCardsFour, centerCardsFive);
    printf("move> ");
    scanf("%d", move);
    row=move[0];
    col=move[1];
    toStack=move[2];
    centerCardStack(row, col, toStack);
    printf("aftermove: %2d|%2d|%2d|%2d|%2d\n", centerCardsOne, centerCardsTwo, centerCardsThree, centerCardsFour, centerCardsFive);
}

我正在使用GCC 7.4.0和64位Linux Mint 19.3，在带有Intel Core 2 Duo @ 2.2 Ghz（Intel Centrino）的Gateway NV78笔记本电脑上运行。我没有看到任何可以帮助我的东西。谁能帮我？我从代码中得到的只是头疼...

我已经找到答案！感谢kaylum的建议，我使用了scanf("%d%d%d", &row, &col, &toStack);，从而解决了我的问题。我试图scanf("%d", move);读取整个scanf以移动到单独的区域，但这没有用。现在，我可以使用一个函数来编辑不同的int。
