String concatenation is a common task in most applications. In this article, we will look into different ways to concatenate strings in Python. 1.Using the + operator To concatenate strings we can use the + operator. Output Here string str1 and str2 are joined using the + operator. We can add space between str1 and … Read more
Splitting string into sub-strings is a common task in many applications. In this article, we will discuss various ways to split strings in C++. 1.Using the getline function The getline function can be used to split strings in C++. is : Extact string from istream object str : extracted line string delim : delimiter character … Read more
In this article, we will discuss string::npos in C++. The std::string::npos is a static member constant. It is defined in the string (basic_string.h) header file. It is a static member constant with the maximum value representable by the type size_type. The type of size_type is unsigned integer however it is initialized as -1 but due … Read more
In this article, we will discuss pure virtual functions in C++ and usage with examples. Let’s dive into the definition of pure virtual function. So what is pure virtual function? A pure virtual function is a function, that must be overriden in the derived class need not to be defined A virtual function can be … Read more
In this article, we will discuss different ways to read strings from input in C++. The cin object and getline function can be used to read strings. Using the cin to read string input In this example, we will use cin object to read strings. The cin is an istream object. Output Note that there … Read more
In this article, we will discuss virtual destructors in CPP. Destructor is part of Resource Acquisition Is Initialization(RAII) programming idiom. The basic idea of RAII is constructor will acquire(allocate) resources and the destructor will release resources for a class. The most common example of a destructor is when the constructor uses new, and the destructor … Read more
In this article, we will discuss the size of C++ classes. We will look into an empty class, a class with member function, a class with virtual functions, and a class with data members. We will be using a 64-bit machine to compile the test code. For a 64-bit machine, the pointer size is 8 … Read more
In this article, we will discuss various methods to check substring in python string. There are two ways to check substring in python. Using the in operator The simplest way to check the substring python string is using the in operator. To test the membership we can use in and not in operators. For strings, … Read more
Have you ever thought about the shortest C++ program? In this article, we’ll look into the shortest C++ program. C++ is a compiled language. Firstly, the compiler processes the source code files and produces object files. The linker will combine these object files to yield an executable program. Let’s look into the smallest C++ program … Read more
In this article, we will discuss various methods to convert std::string to int in C++. 1.Convert string to int using atoi function The atoi function parses C-style string (null-terminated) content as an integer. Syntax of atoi Defined in header <cstdlib> (stdlib.h) Arguments str – C- style null-terminated string Returns On success, returns the converted number … Read more
