Chapter 2: Problem 18

Write statements that do the following: a) Declare a char variable named letter. b) Assign the letter A to the letter variable. c) Display the contents of the letter variable.

Short Answer

Expert verified
Answer: The three steps are: 1. Declare the char variable 'letter' with the code: `char letter;` 2. Assign the value 'A' to the variable 'letter' using: `letter = 'A';` 3. Display the content of the 'letter' variable using `std::cout << "The content of the letter variable is: " << letter << std::endl;`

Step by step solution

01

Declare a char variable named letter.

To declare a 'char' variable named 'letter', simply write: ```cpp char letter; ```
02

Assign the letter A to the letter variable.

To assign the letter 'A' to the variable 'letter', write: ```cpp letter = 'A'; ``` Make sure to use single quotes for character literals.
03

Display the contents of the letter variable.

To display the content of the variable 'letter', you need to use the 'cout' command along with the '<<' operator. Write: ```cpp #include int main() { char letter; letter = 'A'; std::cout << "The content of the letter variable is: " << letter << std::endl; return 0; } ``` This will display the content of the variable 'letter' on the screen.
