What is the purpose of a 'for loop' in programming?

• To iterate over a sequence of elements and execute a block of code for each element.

• To make the code run faster

• To automatically generate random values

• To skip executing certain lines of code

Answer explanation

The purpose of a 'for loop' in programming is to iterate over a sequence of elements and execute a block of code for each element.

What is the difference between '==', '===', and '!=' in programming?

• '==' checks for equality, '!=' checks for strict equality, and '===' checks for inequality.

• '=' checks for equality, '==' checks for strict equality, and '!=' checks for inequality.

• '==' checks for equality, '===' checks for strict equality, and '!=' checks for inequality.

• '===' checks for equality, '!=' checks for strict equality, and '==' checks for inequality.

Answer explanation

'==' checks for equality, '===' checks for strict equality, and '!=' checks for inequality.

Explain the concept of 'inheritance' in object-oriented programming.

• Inheritance is a mechanism in which a class can only inherit from one parent class.

• Inheritance is a mechanism that allows classes to inherit private members from other classes.

• Inheritance is a mechanism in which a class inherits properties and methods from a subclass.

• Inheritance is a mechanism in which a new class is created using properties and methods of an existing class. The new class is called a derived class or child class, and the existing class is called a base class or parent class.

Answer explanation

Inheritance is a mechanism in which a new class is created using properties and methods of an existing class. The new class is called a derived class or child class, and the existing class is called a base class or parent class.

What is the significance of 'git' in version control systems?

• Git is not compatible with any programming languages.

• Git simplifies the process of version control and enables better collaboration among developers.

• Git is only used for storing code locally.

• Git makes it harder for developers to collaborate.

Answer explanation

Git simplifies the process of version control and enables better collaboration among developers by allowing for efficient tracking of changes and easy merging of code.

What is the role of a 'compiler' in the process of programming?

• Creates user interfaces

• Optimizes database queries

• Generates test cases

• Translates high-level code into machine code

Answer explanation

The role of a compiler is to translate high-level code into machine code, making it understandable by the computer for execution.

Describe the difference between 'local' and 'global' variables in programming.

• Local variables can be accessed from anywhere in the program, while global variables are limited to a specific scope.

• Local variables are declared outside of functions, while global variables are declared within functions.

• Global variables are temporary, while local variables are permanent.

• Local variables are limited to a specific scope, while global variables can be accessed from anywhere in the program.

Answer explanation

Local variables are limited to a specific scope, while global variables can be accessed from anywhere in the program.

What is the function of 'if-else statements' in programming?

• Random selection of code to execute

• Conditional execution of code based on specified conditions.

• Skipping code execution based on user input

• Repetitive execution of code without conditions

Answer explanation

The function of 'if-else statements' in programming is conditional execution of code based on specified conditions.

How does 'debugging' help in the development of computer programs?

• Debugging is only necessary for small programs.

• Debugging is a process that speeds up the program execution.

• Debugging helps in creating new features for the program.

• Debugging helps in identifying and fixing errors in the code.

Answer explanation

Debugging helps in identifying and fixing errors in the code.
