Lesson 4 - intro to String Handling.pptx
- 2. String Handling In C++, strings are sequences of characters that are widely used for storing and manipulating text-based data. String handling involves various operations such as concatenation, comparison, copying, etc.
- 3. Definition and Properties of Strings In C++, strings are represented using the std::string class from the C++ Standard Library. Here are some important properties of strings: 1. Strings are mutable: Unlike in C, strings in C++ can be modified directly without creating a new string. 2. Strings are not null-terminated: In C++, the std::string class takes care of storing the length of the string, so there is no need for a null character.
- 4. String Operations String Input String input is the process of obtaining a sequence of characters (a string) from a user or an input source. In C++, you can use the std::cin object along with the >> extraction operator to read strings from the standard input.
- 6. String Concatenation String concatenation is the process of combining two or more strings into a single string. In C++, you can concatenate strings using the + operator or the append member function of the std::string class.
- 8. String Comparison String comparison is used to determine the order or equality of two strings. In C++, you can compare strings using the comparison operators (<, >, <=, >=, ==, !=) or the compare member function of the std::string class.
- 10. String Copying String copying involves copying the contents of one string to another. In C++, you can simply assign one string to another using the assignment operator (=). String copying involves copying the contents of one string to another. In C++, you can simply assign one string to another using the assignment operator (=).
