Question: Break down the given C++ programs A) to divide a number by 2 and B) to get the user's name and display it, step by step. Answer: A) Program to divide a number by 2: 1. Include the iostream header and use the "std" namespace. 2. Declare the main function and variables 'number' and 'half'. 3. Display a console message for the user to input a number. 4. Take the input number from the user and store it in the 'number' variable. 5. Divide the 'number' variable by 2 and store the result in the 'half' variable. 6. Display the result using the 'cout' command and 'half' variable. B) Program to get user's name and display it: 1. Include the iostream header and use the "std" namespace. 2. Declare the main function with the 'int' return type and variables 'name' and 'go'. 3. Display a console message for the user to input their name. 4. Set the input width for 'name' to 20 characters and use the 'getline' function to get the user's name. 5. Display the user's name using the 'cout' command and the 'name' variable. 6. Ask the user to press the ENTER key to end the program and use the 'cin' command to proceed upon pressing ENTER. 7. Return 0 at the end of the main function.
