A nested loop is a loop within a loop. The outer loop changes only after the inner loop is completely finished / interrupted. In this case, test cases should be designed in such a way that Start at the innermost loop. Set all the outer loops to their minimum values. Perform Simple loop testing o...

Two loops are concatenated if it’s possible to reach one after exiting the other on same path from entrance to exit. Sometimes these two loops are independent to each other. In those cases we can apply the design techniques specified as part of single loop testing. But if the iteration values in on...

The simplest approach to the problem (and the most commonly used so far) is to split sentences into tokens. Simplifying, words have abstract and subjective meanings to the people using and receiving them, tokens have an objective interpretation: an ordered sequence of characters (or bytes). Once sen...

The core data structure in numpy is the ndarray (short for n-dimensional array). ndarrays are homogeneous (i.e. they contain items of the same data-type) contain items of fixed sizes (given by a shape, a tuple of n positive integers that specify the sizes of each dimension) One-dimensional ar...

Associated objects are useful when you want to add functionality to existing classes which requires holding state. For example, adding a activity indicator to every UIView: Objective-C Implementation #import <objc/runtime.h> static char ActivityIndicatorKey; @implementation UIView (Ac...

Integral type ranges ( IntRange , LongRange , CharRange ) have an extra feature: they can be iterated over. The compiler takes care of converting this analogously to Java's indexed for-loop, without extra overhead for (i in 1..4) print(i) // prints "1234" for (i in 4..1) print(i) // pri...

Is it possible to iterate over numbers with arbitrary step, not equal to 1? Sure, the step() function will help you for (i in 1..4 step 2) print(i) // prints "13" for (i in 4 downTo 1 step 2) print(i) // prints "42"

By default structures are padded in C. If you want to avoid this behaviour, you have to explicitly request it. Under GCC it's __attribute__((__packed__)). Consider this example on a 64-bit machine: struct foo { char *p; /* 8 bytes */ char c; /* 1 byte */ long x; /* 8 bytes */ ...

Like other value types, GUID also has a nullable type which can take null value. Declaration : Guid? myGuidVar = null; This is particularly useful when retrieving data from the data base when there is a possibility that value from a table is NULL.
