CS I for Engineering (CSEN102): Basic C++ Program Structure & Sequential Operations

Fill-in-the-blank practice flashcards covering basic C++ program structure, I/O streams, namespaces, variables, constants, fundamental data types, arithmetic operators, and sequential operations.

In C++, the preprocessor directive #include <iostream> instructs the compiler to include the __________ library.

input/output

The execution of every C++ program begins at the starting point known as the __________ function.

int main()

In the main() function, the statement return 0; signals that the program ended __________.

successfully

A collection of pre-written code that provides ready-made tools to avoid writing everything from scratch is called a __________.

library

In C++, the concept of a "stream" refers to a __________ of data traveling into or out of a program.

flow

A declarative region that holds identifiers such as functions, classes, and variables to prevent naming conflicts is called a __________.

namespace

Specifying using namespace std; allows programmers to refer directly to cout instead of writing __________.

std::cout

While convenient for beginners, using using namespace std; is often avoided in larger programs because it can cause __________ if two namespaces have matching names.

confusion

In C++, __________ allows the computing agent to receive values from the user via cin for subsequent computations.

input

In C++, communicating the results of computations back to the user via cout is known as __________.

output

A named storage location in computer memory that holds a value capable of being retrieved or modified is called a __________.

variable

In C++, declaring a variable informs the compiler of its name and type while reserving space in __________.

memory

An uninitialized variable in C++ can lead to unexpected behavior because it often holds an undefined or __________ value.

garbage

A variable whose value cannot be altered once it has been initialized is known as a __________.

constant

Using the const keyword instead of #define is preferred in modern C++ because const adheres to C++ __________ rules.

type

By common programming convention in C++, constant names are typically written in __________.

UPPER_CASE

In C++, the char data type occupies a memory size of __________ byte(s) and is used to store individual characters.

$$1$$

In C++, the int data type typically occupies __________ bytes of memory and represents whole numbers.

$$4$$

While a single-precision float occupies $4\text{ bytes}$, a double-precision double occupies __________ bytes.

$$8$$

The C++ arithmetic operator % is known as the __________ operator and returns the remainder after integer division.

modulus

In C++, the operator ++ is called the __________ operator because it increases the value of a variable by $1$.

increment

A computational process where steps execute strictly one after another in order without decisions or loops is known as a __________ operation.

sequential

As shown in the control flow diagram, the three fundamental types of program operations are Sequences, Selections, and __________.

Loops

According to the C++ data types hierarchy diagram, class, structure, union, typedef, and using belong to the category of __________ Data Types.

User Defined
