I'll go with A too

Answer is A. If I`ve some values in the U8 Array there is no change in the result?

[LordNobady]

no it is just the type to cast to. thy typecast only tells the compiler that from that moment on the value is to be seen as the given type. if the type is not compatible I don't know what it will do. In C it can crash.

WARNING it converts it at byte level not value level. so casting an int to a double will not give you the same value.

Typecasts are some of the most powerful programmers tools. ( and with grate power comes grate responsibility ) use with care.

Can anyone explain to me this concept please?

[crossrulz]

Which concept?  The Type Cast?  The Type Cast just changes how the raw binary data is interpreted.  In this case, the data in the string is being reinterpreted as a byte array (U8).  This is the same thing as using the String To Byte Array function.

[JasonDiv]

So the equal? is actually comparing data types instead of the actual values?

[crossrulz]

No.  The Equal is comparing the data in the arrays.  It was set to compare Aggregates, which returns a single boolean for if the entire arrays were the same.  You can also setup the equal to compare Elements, which will return an array of booleans indicating if the corresponding elements were the same.

Thanks crossrulz.. Am now a follower of the The Daily CLAD
