C String Declaration Syntax

Below is the basic syntax for declaring a string. char string_name[size]; In the above syntax string_name is any name given to the string variable and size is used to define the length of the string, i.e the number of characters strings will store.

But you can also declare a string variable like this: var myName = "your name"; "your name" is called a string literal. A string literal, or string, is a series of zero or more characters enclosed in single or double quotes.

C++ specific data types

Two such data types are strings and streams. A C++ string comes from the string library and can hold any number of characters (char). C++ strings can be compaired to each other using ==, they can tell you how many characters the string holds, and can even search for substrings.

To store the words, a 2-D char array is required. In this 2-D array, each row will contain a word each. Hence the rows will denote the index number of the words and the column number will denote the particular character in that word.

To declare (create) a variable, you will specify the type, leave at least one space, then the name for the variable and end the line with a semicolon ( ; ).

In C programs, variables may be declared to hold a single character data item by using the keyword char as the type specifier in the declaration statment: char ch; A character constant is written surrounded by single quotation marks, e.g. 'a', 'A', '$', '!'

Assign value to strings

Assign the value to a character array while initializing it, explained above. We can use the strcpy() function to copy the value we want to assign to the character array.

How to declare initialize a string in C? ›

A more convenient way to initialize a C string is to initialize it through character array: char char_array[] = "Look Here"; This is same as initializing it as follows: char char_array[] = { 'L', 'o', 'o', 'k', ' ', 'H', 'e', 'r', 'e', '\0' };

Ans: string functions in c are declared as arrays of characters. Each character in the string is stored in a separate element of the array, and the last element of the array is a null character '\0'. For example, char str[SIZE];.

One of the most useful data types supplied in the C++ libraries is the string. A string is a variable that stores a sequence of letters or other characters, such as "Hello" or "May 10th is my birthday!". Just like the other data types, to create a string we first declare it, then we can store a value in it.

C++ strings are sequences of characters stored in a char array. Strings are used to store words and text. They are also used to store data, such as numbers and other types of information.

The C++ getline() is a standard library function that is used to read a string or a line from an input stream. It is a part of the <string> header. The getline() function extracts characters from the input stream and appends it to the string object until the delimiting character is encountered.

If we want to assign any string value to a variable, we will use strcpy as follows. strcpy(p1.name, "Brown"); Now let's store the details of all the three students. Always use strcpy to assign a string value to a string variable.

The assignment ( = ) operator is used to assign a value to a variable or property. The assignment expression itself has a value, which is the assigned value. This allows multiple assignments to be chained in order to assign a single value to multiple variables.

Assign the memory address of the variable to the pointer using the address-of operator (&): This operator is used before the variable name and returns the memory address of the variable. For example, to store the address of 'x' in the pointer 'p', you will write p = &x .
