[問題] 使用struct宣告的矩陣
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
dec-c++
額外使用到的函數庫(Library Used): (Ex: OpenGL, ...)
#include <cstdlib>
#include <iostream>
問題(Question)：
struct str
{
int size;
int direction;
};
int main()
{
str fgu[3][3];
for(int x=0;x<=3;x++)
for(int y=0;y<=3;y++)
fgu[x][y].size=0;
fgu[1][0]=9;
for(int y=0;y<=3;y++)
{
for(int x=0;x<=3;x++)
{
cout<<fgu[x][y].size<<" ";
}
cout<<endl;
}
system("PAUSE");
return EXIT_SUCCESS;
}
預期的正確結果(Expected Output)：
0 9 0 0
0 0 0 0
0 0 0 0
0 0 0 0
錯誤結果(Wrong Output)：
0 9 0 0
0 0 0 0
0 0 0 0
9 0 0 0
這問題感覺很淺...可是我花了好多時間 還是沒解決...
錯的那兩個9 難道記憶體位址是一樣的嗎
拜託各位大大了 謝謝
