How to make a chessboard in C?
提问by Shamveel Ahammed
I am new to C and I am trying to make a program that would output a chessboard pattern. But, I don't understand what my next steps are going to be . Could anyone help me with this?
我是 C 的新手，我正在尝试制作一个可以输出棋盘图案的程序。但是，我不明白我的下一步将是什么。有人可以帮我解决这个问题吗？
Main:
主要的：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdbool.h>
int main() {
int length,width;
enum colors{Black,White};
printf("Enter the length:\n");
scanf("%d",length);
printf("Enter the width:\n");
scanf("%d",width);
int board[length][width];
createBoard(length,width);
for(int i =0;i< sizeof(board);i++) {
if(i%2==0) {
// To print black
printf("[X]");
}
else {
// To print white
printf("[ ]");
}
}
} //main
CreateBoard function:
创建板功能：
int createBoard(int len, int wid){
bool b = false;
for (int i = 0; i < len; i++ ) {
for (int j = 0; j < wid; j++ ) {
// To alternate between black and white
if(b = false) {
board[i][j] = board[White][Black];
b = false;
}
else {
board[i][j] = board[Black][White];
b = true;
}
}
}
return board;
}

Firstly learn how to use scanf().
首先学习如何使用scanf()。
int length;
Incorrect: scanf("%d",length); Correct: scanf("%d",&length);
不正确： scanf("%d",length); 正确： scanf("%d",&length);
Hope this helps:
希望这可以帮助：
#include <stdio.h>
int main(void)
{
int length,width,i,j;
printf("Enter the length:\n");
scanf("%d",&length);
printf("Enter the width:\n");
scanf("%d",&width);
for(i=1;i<=length;i++)
{
for(j=1;j<=width;j++)
{
if((i+j)%2==0)
printf("[X]");
else printf("[ ]");
}
printf("\n");
}
return 0;
}
Note: Make sure length and width are of even length.
注意：确保长度和宽度的长度相等。
