The XOR operator(^), also known as "exclusive OR", is one of the types of bitwise operators, which compares each bit of the first operand to the corresponding bit of the second operand and returns 1 if both bits are different, else returns 0 if both are the same. This only works with integral data types like int, char, short, long, and unsigned int, etc, and cannot be directly used with float, double, string, and class/struct objects, etc. Syntax Here is the following syntax of Bitwise XOR. result = operand1 ^ operand2; Where operand1 and operand2 are the integral types (like ...

The single operators operate on one quantity and following are the samples of single operators − - The increment ( ) and decrement (--) operators. The compiler distinguishes between the different meanings of an operator by examining the types of its operands.The unary operators operate on a single operand and following are the examples of Unary operators −The increment (++) and decrement (--) operators.The unary minus (-) operator.The logical not (!) operator.The unary operators operate on the object for which they were called and normally, this operator appears on the left side of the object, as in !obj, -obj, and ...

Consider a situation, when we have two persons with the same name, Piyush, in the same class. Whenever we need to differentiate them definitely we would have to use some additional information along with their name, like either the area, if they live in a different area or their mother’s or father’s name, etc.The same situation can arise in your C++ applications. For example, you might be writing some code that has a function called xyz() and there is another library available which is also having same function xyz(). Now the compiler has no way of knowing which version of ... Read More

The unary operators are operators that operate only on a single operand. There are mainly thirteen unary operators in C++, for example, ++, !, ~, typeof, delete, etc.Overloading a unary operator means setting a customized behaviour for the unary operators for the objects of a class. which means you can define how an operator will work when applied to instances of a class instead of using its default behavior. This operator is generally used on the left side of the object, as in +obj, !obj, -obj, and ++obj, but can also be used as a postfix like obj++ or obj--. So, ... Read More

Unary operators are operators that operate only on a single operand (unlike binary operators, which operate on two operands). There are mainly thirteen unary operators that exist in C++, for example, ++, !, ~, typeof, delete, etc. Overloading Unary Minus Operator Overloading a unary operator means defining a custom behavior for the unary operators while applying it to objects of a class. which means you can define how an operator will work when applied to instances of a class instead of using its default behavior. This operator is normally used on the left side of the object, as in +obj, ... Read More

The term Whitespace in C++ refers to the characters used for formatting, like creating spaces, tabs, and newlines. These are usually invisible in the source code output (meaning they don't appear in the actual program output); they just help to format the code and improve readability. Types of whitespace characters Here are the following four common types of whitespace characters mostly used in C++. Space (' ') Tab ('\t') Newline ('') Carriage return ('\r') Space (' ') It's a most basic whitespace ... Read More

The loop control statement continue abandons the pending statements in current iteration of the looping block and starts next iteration. The continue statement appears in a conditional block inside loopExamplex=0 while x

Converting a for loop to a while loop in Python means rewriting the loop logic in a different way to perform the same task.While loop gives better control over conditions and is also useful for cases when the number of iterations is not fixed and depends on runtime values. Therefore, sometimes while is preferred over a for loop when the loop's continuation depends on dynamic conditions. For Loop Code Here is the following simple for loop that traverses over a range. for x in range(5): print(x) Output 0 1 2 3 4 To convert ... Read More

In this article, we will learn to print Hello World without a semicolon in C++. The semicolon (;) is used to terminate statements. The above can be achieved by using control structures like loops, conditionals, or function calls. Different Approaches There are multiple ways to write a C++ program without semicolons − Using if Statements Using a while Loop Using Switch Statement Note: Doing this is a very bad practice and should never be used in real code. This is presented just as informational content. ... Read More

Infinite loop is the one that doesn't stop on its own. It happens when the looping condition continues to remain true forever. In such a case, the loop must be forcibly stopped by pressing ctrl-C to generate keyboard interrupt
