nds 陸行鳥與魔法繪本 當機

進入 冰與火 這個遊戲的單人模式

會黑屏..我試了6次-7次都這樣(而且還去格式化)

我的解決辦法(我試3次都可以解決)

先按閱讀故事 然後跳出 在選單人模式就OK

Generate random number in a loop and call srand one time when function be called

In stdlib.c, the random seed "holdrand= 1L".

If you don't change random seed,
random sequence will be same when you execute program.

To change seed can use srand().

In some situation, function will be called repeatedly.
You want to call srand() just one time, how to do??

There is a soluation.
Because the first rand() value will be 1804289383.

We can design the code:
=======================================
int GetRandomNum() {

    int tempnum = rand();
    if ( 1804289383 == tempnum ) {
        srand( time(NULL) );
    }

    for ( int i = 0 ; i < ( maxnum - minnum ) ; i++ ) {
        outValue = minnum + tempnum%( maxnum - minnum + 1 );

        if ( outValue != xx ) {
            return outValue;
        }
        tempnum = rand();
    }

}
=======================================

It will guarantee "srand()" will be executed once.
Have fun!!
