What is the purpose of an API in software development?
A Code execution
B Communication between systems
C User interface design
D Database management
An API (Application Programming Interface) allows different software systems to communicate with each other. It provides a set of rules and protocols for accessing the features of a system, such as retrieving data or sending commands.
Which phase of the Software Development Life Cycle (SDLC) involves gathering and analyzing user requirements?
A Testing
B Design
C Implementation
D Requirement analysis
In the SDLC, the requirement analysis phase is crucial as it involves gathering and documenting what the user needs. This phase ensures that developers understand the project’s goals and user requirements before designing and building the system.
What is the main goal of software testing?
A Verify functionality
B Write documentation
C Debug code
D Design system
The main goal of software testing is to verify that the software functions as intended. This process identifies bugs, ensures that the system meets user expectations, and confirms that it operates correctly under various conditions.
Which method is used in Python for debugging to stop the program at a specific point?
A log()
B debug()
C breakpoint()
D print()
In Python, the breakpoint() function is used to pause the execution of the program at a specific point. This allows developers to inspect the current state of variables and control the flow of execution during debugging.
In Java, what is the purpose of the main() method?
A To create objects
B To execute code
C To handle exceptions
D To define classes
In Java, the main() method is the entry point of a program. It is where the execution starts, and the Java Virtual Machine (JVM) looks for the main() method to begin running the program.
What is the purpose of unit testing in software development?
A Test individual components
B Test system integration
C Test user interfaces
D Test deployment
Unit testing involves testing individual components or functions of a program in isolation to ensure they work correctly. It is typically done by developers to verify that each piece of the code behaves as expected.
Which of these is used to manage software versions?
A SQL
B Apache
C Node.js
D Git
Git is a version control system used to manage and track changes to software code. It allows developers to collaborate efficiently, keep track of changes, and revert to previous versions if needed.
What does the acronym SDLC stand for in software development?
A System Development Life Cycle
B Software Design Life Cycle
C Software Development Language Coding
D Software Design and Logic Circuits
SDLC stands for System Development Life Cycle, which is a structured process for planning, creating, testing, and deploying software. It consists of phases like requirement gathering, design, implementation, and maintenance.
Which of the following tools is commonly used for debugging in C?
A gdb
B assert()
C log()
D printf()
In C, gdb (GNU Debugger) is a powerful tool used for debugging. It allows developers to inspect the state of the program, step through code, and track down the source of bugs.
Which type of testing checks the interaction between different software components?
A System testing
B Integration testing
C Acceptance testing
D Unit testing
Integration testing verifies the interaction between different components or modules of a system to ensure they work together as expected. It follows unit testing and helps identify issues in the communication between modules.
In Python, which function is commonly used to handle exceptions?
A throw()
B catch()
C try-except
D raise()
In Python, the try-except block is used to catch and handle exceptions. The code in the try block is executed, and if an error occurs, the except block catches the exception and handles it appropriately.
In the SDLC, which phase involves developing and writing the actual code?
A Testing
B Design
C Deployment
D Implementation
The implementation phase of the SDLC is where the actual software is built and the code is written. It turns the design and specifications into functioning software by translating them into code using appropriate programming languages.
What is the purpose of version control systems like Git in programming?
A To run the code
B To compile the code
C To track changes in code
D To test the code
Version control systems like Git help track changes to source code over time. They allow developers to collaborate, manage different versions of the code, and revert to earlier versions if needed.
What is the first step in the Software Development Life Cycle (SDLC)?
A Implementation
B Requirement gathering
C Testing
D Design
The first step in the SDLC is requirement gathering, where developers and stakeholders define and document the system’s functional and non-functional requirements. This ensures that the software meets user needs and expectations.
In Java, what is used to handle multiple exceptions in a single catch block?
A || operator
B | operator
C catch-all
D , operator
In Java, the || operator is used to handle multiple exceptions in a single catch block. You can specify multiple exception types separated by the | symbol, allowing one block to handle multiple exceptions simultaneously.
