曾經幫別人答過，程式碼如下：

#include

#include

#include

int main()

{

int nAppValue, nUserValue, iCount = 0;

srand( time( 0 ) );

nAppValue = rand() % 100 + 1;

printf( "請猜我選中的是哪個數字(1-100)?\n" );

do

{

scanf( "%d", &nUserValue );

++iCount;

if( nUserValue == nAppValue )

{

printf( "猜了%d次, 猜中了！\n",iCount );

break;

}

else if( nUserValue > nAppValue )

{

printf( "錯了！再小點, 繼續猜！\n" );

}

else

{

printf( "錯了！再大點！繼續猜！\n" );

}

}while(1);

printf( "遊戲結束！\n" );

return 0;

}
