Interview Questionnaire
20 Questions
- Q1. What is memory leak?
- Ans.
Memory leak is a condition where a program fails to release memory it no longer needs, leading to memory consumption and performance issues.
Memory leak occurs when dynamically allocated memory is not deallocated properly.
It can happen when a program loses the reference to allocated memory without freeing it.
Memory leaks can gradually consume all available memory, causing the program or system to crash.
Common causes inc...
- Q2. What is static variable in C? with program
- Ans.
A static variable in C is a variable that retains its value between function calls.
Static variables are declared using the 'static' keyword.
They are initialized only once, at the start of the program.
Their value persists even after the function call ends.
Static variables have a default initial value of 0.
They are useful for maintaining state across function calls.
- Q3. What are local variable and global variables? and their default values and program
- Ans.
Local variables are declared within a specific function or block, while global variables are declared outside of any function or block.
Local variables have a limited scope and are only accessible within the function or block where they are declared.
Global variables can be accessed from anywhere in the program.
Local variables are created when a function is called and destroyed when the function ends.
Global variables are...
- Q4. What is method overriding? with program
- Ans.
Method overriding is a feature in object-oriented programming where a subclass provides a different implementation of a method that is already defined in its superclass.
Method overriding is used to achieve runtime polymorphism.
The method in the subclass must have the same name, return type, and parameters as the method in the superclass.
The @Override annotation can be used to indicate that a method is intended to overr...
- Q5. What is cache memory?with real time example
- Ans.
Cache memory is a small, fast memory that stores frequently accessed data for quick access.
Cache memory is faster than main memory but smaller in size.
It reduces the time taken to access data from main memory.
Examples include CPU cache, web browser cache, and disk cache.
Cache memory is volatile and can be cleared at any time.
Cache hit is when data is found in cache, cache miss is when it's not.
- Q6. Differences between C and Java?
- Ans.
C is a procedural language while Java is an object-oriented language.
C is compiled while Java is interpreted
C has pointers while Java does not
Java has automatic garbage collection while C does not
Java has platform independence while C does not
Java has built-in exception handling while C does not
- Q7. Explain me about exception handling? with program
- Ans.
Exception handling is a mechanism to handle runtime errors and prevent program crashes.
Exceptions are objects that represent errors or exceptional situations in a program.
When an exception occurs, the program stops executing and jumps to the nearest exception handler.
Exception handling involves catching and handling exceptions to prevent program crashes.
Try-catch blocks are used to catch and handle exceptions.
Example: ...
- Q8. Run time exceptions?
- Ans.
Run time exceptions are errors that occur during program execution.
They are unexpected and can cause the program to crash.
Examples include null pointer exceptions and arithmetic exceptions.
They can be handled using try-catch blocks.
Proper error handling can prevent run time exceptions.
- Q9. What is stack?operations and program
- Ans.
A stack is a data structure that follows the Last In First Out (LIFO) principle.
Elements are added to the top of the stack and removed from the top.
Common operations include push (add element to top) and pop (remove element from top).
Stacks are used in programming for function calls, expression evaluation, and memory management.
Example: The back button in a web browser uses a stack to keep track of visited pages.
