A particular way of storing and organizing data in a computer so that it can be used efficiently.
Explanation
A data structure refers to a specific method or technique used to store and organize data in a computer system. It enables efficient usage of the data by providing a framework for how the data is stored, accessed, and manipulated. Different types of data structures, such as arrays, linked lists, stacks, queues, trees, and graphs, have different characteristics and are suited for different types of data and operations. By choosing an appropriate data structure, developers can optimize the performance and efficiency of their programs.Rate this question:

Specifies a file to be included
Explanation
The answer is #include because it specifies a file to be included in the current source code file. This preprocessor directive is commonly used in C and C++ programming languages to include header files that contain function prototypes, definitions, and other declarations needed for the program to compile and run successfully. The included file is typically a library or another source code file that provides additional functionality or definitions required by the program.Rate this question:

Tag for Stands for "standard input/output header"
Explanation
The tag "Stands for 'standard input/output header'" is used to indicate that the given tag is an abbreviation for the term "standard input/output header". This term refers to a header file in programming languages that provides functions for input and output operations, such as reading from and writing to the console.Rate this question:
- 7.
It is a tag for C header file used in old MS-DOS compilers to create text user interfaces
Explanation
The correct answer is <conio.h>. This header file was used in old MS-DOS compilers to create text user interfaces. It provided functions for console input/output and screen manipulation, allowing developers to create interactive programs with menus, windows, and other UI elements in a text-based environment. The <conio.h> header is not a standard part of the C language and is not supported by modern compilers, but it was widely used in the past for MS-DOS programming.Rate this question:

Set of Instruction
- 9.
A function which has its protype defined in conio.h header file
Explanation
The function "getch()" is a function that is defined in the "conio.h" header file. This function is used to read a single character from the keyboard without displaying it on the screen. Therefore, the correct answer is "getch()".Rate this question:

A graphical or symbolic representation of a process.
Explanation
A flow chart is a visual representation or diagram that uses symbols to depict the steps or stages of a process. It shows the flow of information or actions from one step to another, making it easier to understand and analyze the process. Flow charts are commonly used in various fields such as programming, engineering, and business to illustrate processes, decision-making, and workflows.Rate this question:
- 11.
An oval flow chart shape indicating the start or end of the process.
Explanation
The given answer, "Terminator," is correct because an oval flow chart shape is commonly used to represent the start or end of a process in flowcharts. It is called a "Terminator" because it marks the beginning or end point of the process flow. This shape is used to indicate where the process starts or ends, and it helps to clearly define the boundaries of the process being represented in the flowchart.Rate this question:
- 12.
A rectangular flow chart shape indicating a normal process flow step.
Explanation
The given correct answer is "Process" because a rectangular flow chart shape indicates a normal process flow step. In a flow chart, different shapes are used to represent different elements of a process. The rectangular shape specifically represents a process or a task that needs to be performed. Therefore, "Process" is the appropriate answer in this case.Rate this question:
- 13.
A diamond flow chart shape indication a branch in the process flow.
Explanation
The correct answer is "Decision" because a diamond flow chart shape is commonly used to represent a decision point in a process flow. This shape indicates that the process flow will branch out into different paths based on the decision made at this point. It is a visual representation of a decision-making process within the overall flow chart.Rate this question:
- 14.
A small, labeled, circular flow chart shape used to indicate a jump in the process flow.
Explanation
A connector is a small, labeled, circular flow chart shape that is used to indicate a jump in the process flow. It is typically used to connect different parts of a flowchart that are not directly connected in sequence, allowing for a non-linear flow of the process. Connectors help to visually represent the flow of information or steps in a process, making it easier to understand and follow.Rate this question:
- 15.
A parallelogram that indicates data input or output (I/O) for a process.
Explanation
The given answer "Data" is the correct answer because it accurately describes the content represented by the parallelogram in the context of the question. In process flowcharts or diagrams, a parallelogram is commonly used to represent data input or output (I/O) for a process. Therefore, the answer "Data" correctly identifies the content represented by the parallelogram.Rate this question:

The fundamental looping statement in C
Explanation
The for loop is the fundamental looping statement in C. It allows a specific block of code to be executed repeatedly based on a condition. The loop consists of three parts: initialization, condition, and increment/decrement. The initialization is executed once at the beginning, the condition is checked before each iteration, and the increment/decrement is performed at the end of each iteration. If the condition is true, the loop continues executing, otherwise, it terminates. This makes the for loop a powerful tool for iterating over a range of values or performing a certain task a specific number of times.Rate this question:

A common error when writing for the loops is to place a _____ ?
Explanation
A common error when writing for loops is to place a semicolon. This is because the semicolon is used to mark the end of a statement in many programming languages, including C++, Java, and JavaScript. However, in a for loop, the semicolon is used to separate the initialization, condition, and increment sections of the loop. Placing a semicolon in the wrong place can lead to syntax errors and unexpected behavior in the loop. It is important to understand the correct syntax for writing for loops to avoid this common error.Rate this question:

What is the symbol of increment
Explanation
The symbol "++" is the symbol of increment in programming. It is used to increase the value of a variable by 1. It is commonly used in loops or when updating a counter. For example, if a variable "x" has a value of 5 and we use the increment operator "++" on it (x++), the value of "x" will become 6.Rate this question:
- 19.
What is the symbol of decrement
Explanation
The symbol "--" is commonly used to represent the decrement operation in programming languages. It is used to decrease the value of a variable by 1. The double minus sign indicates a decrement by one, similar to how the double plus sign "++" represents an increment by one.Rate this question:
- 20.
What is int stands for?
Explanation
The term "int" stands for "integer." In programming, an integer is a data type that represents whole numbers without any decimal or fractional parts. It is used to store and manipulate numerical values that do not require precision beyond the whole number. The "int" keyword is commonly used in programming languages to declare variables that will hold integer values.Rate this question:
