Definition of character variables in C

Character variables are variable types used to store single characters. In C, you can use the char keyword to define a character variable.

Grammar:

<code class="cpp">char variable_name;</code>

For example:

<code class="cpp">char ch = 'A';</code>

Features:

  • Character variables can only store one character.
  • The default value of character variables is the null character ('\0').
  • Character variables can use single quotes or double quotes when assigning values, but single quotes are recommended.
  • Character variables can use escape sequences to represent special characters, such as '\n' to represent a newline character.

Operation:

  • You can use the assignment operator (=) to assign a value to a character variable.
  • You can use the input and output operators (<< and >>) to read or output characters from the console.
  • Character variables can be compared using comparison operators (==, !=, <, <=, >, and >=).

Note:

  • Character variables can only store characters with ASCII code values ​​between 0 and 255.
  • You cannot directly assign a string to a character variable because the string is a character array.

Sample code:

<code class="cpp">#include <iostream>

int main() {
    char ch;

    std::cout << "Enter a character: ";
    std::cin >> ch;

    std::cout << "The character you entered is: " << ch << std::endl;

    return 0;
}</code>
