Question

我在ci上连接四个游戏编译我的代码，但我仍然有这两个问题首先在我的终端 sh：cls：command not found 我在论坛上搜索（可能是一个分段错误）但我不知道该怎么做才能修复它输入代码这里和第二个当我编译行没有出现在屏幕上你能帮我吗？谢谢你提前：）

就是这样：

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <stdbool.h>
void display();
bool check(int a, int b);

int drop(int b, char player);
char place[6][7];//available for the entire code

    void display(){ //empty 

    printf(" 1   2   3   4   5   6   7\n");                     


    int i,j;

    for (i=0; i<6; i++) {
    printf ("+");
    for (j=0; j<7; j++)
        printf("---+");
    printf ("\n");
    printf ("|");
    for (j=0; j<7; j++)
        printf("   |");
    printf ("\n");
  }

printf ("+");
for (j=0; j<7; j++)
    printf("---+");
printf ("\n");
}

int drop(int b, char player){
        if(b >=0 && b<= 6){
            if(place[0][b] == ' '){
            int i;

您正在使用Linux操作系统原生的system("clear")。但也使用Windows操作系统原生的system("cls")。下定决心，因为这会导致你的错误。

您实际上可以detect which OS you are running使用一些预定义的宏。
