What is the purpose of the std::istream in a C++ program?
What is the purpose of the std::istream in a C++ program?
- To manage multiple streams of input simultaneously.
- To move data from a variable to the console output.
- To move data from the keyboard to a variable in the program. (correct)
- To declare and define variable types in a program.
What happens to the input data after whitespace is encountered during input?
What happens to the input data after whitespace is encountered during input?
- The next input reads immediately after the whitespace.
- All remaining data is cleared from the input stream.
- Data past the whitespace remains in the input stream for future use. (correct)
- Whitespace is treated as a valid input, affecting the subsequent readings.
Which of the following is essential before using any variable in a C++ program?
Which of the following is essential before using any variable in a C++ program?
- The variable must be assigned a value from the keyboard.
- The variable must be initialized to zero.
- The variable name must be unique.
- The variable must be declared first. (correct)

Sequence Program
Sequence Program
A program where instructions are executed one after another in a specific order.
Input/Output Streams
Input/Output Streams
Streams moving data into (input) and out of (output) a program, like data from the keyboard to a variable or data from a variable to the console.

Study Notes
Course Information
- Course name: CSC 1060
- Course topic: IPO Sequence Programs
Objectives
- Understand the C++ program development cycle
- Declare variables using correct data types
- Write a simple C++ program including input, processing, and output instructions using various data types
- Apply coding standards for conventional programming style
Week 4 Agenda
- Programming Ethics (tutorial 1.3, Problem Solving, Interactivity & Ethics)
- What is a program? (tutorial 1.3, What is a Program?)
- What is a sequence program? (student response required)
- Streams (input/output)
- Input, output, and assignment
- Example of a sequence program (Fahrenheit to Celsius conversion)
- Increment and decrement operators (pre/post)
- Operator chaining
- TODO & Resources for Help
Programming Ethics
- Read and complete the activities in the provided tutorial.
What is a Program?
- Read and complete the activities in the provided tutorial.
What is a Sequence Program?
- Students need to provide their own definition.
IO Streams
- Streams move data in and out of a program
- The
<iostream>library defines standard input/output objects std::cinreads input from the keyboardstd::coutdisplays output to the console- Complete the tutorial and answer the quiz questions
C++ Input
- All variables must be declared before use.
- Data entered is read until whitespace (space, tab, or newline).
- Whitespace is left in the input stream for the next input.
C++ Output
- All variables must be declared before use.
- Output is inserted to the console window using
std::cout. - Include whitespace and formatting explicitly.
Assignment and Reassignment
- Complete the tutorial and activities (2.4. Assignment).
- Assignment is represented as
leftVariable = rightValue.
Example Sequence Program (Fahrenheit to Celsius)
- Prompt the user to enter Fahrenheit
- Declare a variable to store the input
- Get the input from the user
- Declare a variable to store the calculated Celsius value
- Perform Fahrenheit to Celsius conversion using the formula
- Output the calculated Celsius value
Type it in and Try It (Increment/Decrement)
- Example of pre- and post-increment/decrement operators.
C++ Operator Chaining
- Input and output can be chained to the same stream object.
- Example chaining input and output for first and last names.
Review Exercises (Sequence)
- Complete the mixed-up code exercises from thinkcpp.
- Choose 5 problems from problems 1-10.
- Change the question type to Parsons (or Active Write and switch back to Parsons)
- Parsons questions are drag and drop code problems.
Earn Pre-Work Grade
- Post weekly discussion question and research solution to D2L.
- Complete Week 04 Content Module in D2L to 100%.
Questions, Clarifications, and Help
- Student office hours (by appointment and drop-in times)
- Email: [email protected]
- RRCC On-Campus Tutoring
- 24/7 Online Tutoring (D2L)
