Question

这段C++输出符号的代码总是出错？

这段代码总是编译不通过，我刚开始用C++，对初始化还不熟，谁能帮我改一下，并解释一下，谢谢谢谢！！

#include "stdafx.h"
#include <iostream>

void PrintBoard()
{
char Board[9][11];

int i, j;
for( i = 0; i < 9; i++ )
for( j = 0; j < 11; j++ ){
if( i == 0 || i == 8 && j == 0 || j== 10 )
strcpy(Board[i][j]," + ");
else if( i == 4 && j == 1 || i == 4 && j == 9 )
strcpy(Board[i][j]," @ ");
else if( 3 < i < 4 && 5 < j < 6 || 6 < i < 7 && 5 < j < 7 )
strcpy(Board[i][j]," * ");
else if( i == 3 && j ==1 || i == 3 && j == 9 || i == 4 && j == 2 || i == 4 && j == 8 || i == 5 && j == 1 || i == 5 && j == 9 )
strcpy(Board[i][j]," # ");
}
for( i = 0; i < 9; i++ )
for( j = 0; j < 11; j++ )
std::cout << Board[i][j];

}

int _tmain(int argc, _TCHAR* argv[])
{
PrintBoard();

return 0;
}
改了一下，编译通过了，但是输出结果不对，我想输出的是

+ *** +
+# *** #+

+ *** +

+++++++++++

Answer 1

1、strcpy(Board[i][j]," + "); // strcpy(&Board[i][j]," + ");
2、3 < i < 4 //这个是习惯上的用法，呵呵，应该是(3 < i && i < 4)

另外不知道你的本意是什么？是这样的
if( i == 0 || i == 8 && j == 0 || j== 10 ) ？
还是if( (i == 0 || i == 8) && (j == 0 || j== 10) ) 呢？
类似的if中的条件你最好都看下，否则谁都不知道程序最终输出的什么...

Answer 2

#include <cstring>
#include <iostream>

void PrintBoard()
{
char Board[9][11];

int i, j;
for( i = 0; i < 9; i++ )
for( j = 0; j < 11; j++ ){
if( i == 0 || i == 8 && j == 0 || j== 10 )
Board[i][j] = '+';
else if( i == 4 && j == 1 || i == 4 && j == 9 )
Board[i][j] = '@';
else if( 3 < i < 4 && 5 < j < 6 || 6 < i < 7 && 5 < j < 7 )
Board[i][j] = '*';
else if( i == 3 && j ==1 || i == 3 && j == 9 || i == 4 && j == 2 || i == 4 && j == 8 || i == 5 && j == 1 || i == 5 && j == 9 )
Board[i][j] = '#';
}
for( i = 0; i < 9; i++ )
for( j = 0; j < 11; j++ )
std::cout << Board[i][j];

}

int main()
{
PrintBoard();

return 0;
}

去翻书，查一下 strcpy() 是怎么用的。
