cout is an object of the stdout stream, while cerr is an object of the stderr stream.stdout and stderr are different streams, even though they both refer to console output by default. Redirecting (piping) one of them (e.g., program.exe >out.txt) would not affect the other. These are both provided by the ... 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 ...

In C++, both relational Operators (==) with std::string and std::string::compare() are used to compare two strings for equality, but there's a minor difference in both of these; == compares and returns the results in Boolean, whereas compare() checks lexicographically and returns the result in integers. In ... Read More

A semicolon in C++ is used to terminate or end the statement; it tells the compiler that this particular instruction is completed.According to the ISO C++ specifications, the lexical representation of C++ programs (breaking down code into small parts) is called tokens. Some of these tokens are punctuators, which are ... 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 ...

We are given an array of integers, and we need to find the maximum sum of a contiguous subarray using Kadane’s Algorithm. Kadane’s Algorithm is an efficient way to find the maximum subarray sum in O(n) time complexity. For example, in the array {-2, 1, -3, 4, -1, 2, 1, ... Read More

In C++, a semicolon(;) indicates the end of a statement in code, or we can say it terminates the statement. When you use a semicolon just after an if or while statement, it creates an empty statement, which executes nothing. Semicolon with If Statement In C++, the if statement is ... Read More

Trigraphs in C++ are special three-character sequences that represent a certain single character, which may not be available on some keyboards or systems. Previously, the ISO-646 character set did not have all the characters of the C syntax; therefore, some systems with their keyboard and display faced problems while dealing ... Read More

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, ... 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 ... Read More
