integer - 默认初始化 Component Pascal 中的变量

Question

默认情况下，整数类型变量以一种奇怪的方式初始化。
看看这段代码：

MODULE MyTest;
    IMPORT Log;
    PROCEDURE Start*;
    VAR a, b, c, d: INTEGER; (* This variables *) 
    BEGIN
        Log.Int(a);
        Log.Ln;
        Log.Int(b);
        Log.Ln;
        Log.Int(c);
        Log.Ln;
        Log.Int(d);
        Log.Ln;
    END Start;
END MyTest

结果如下：

4233640
2287340
2287344
576

谢谢！

Like most Wirthian languages, probably variables(and specially local ones) are probably uninitialized. They may be initialized by chance, but usually there is no guarantee.
