Associate Technology Trainee Interview Questions and Answers

Function definition specifies the implementation of a function, while declaration provides the function signature.

• Function definition includes the function body, while declaration only includes the function signature.

• Function definition is used to define the behavior of a function, while declaration is used to announce the existence of a function.

• Function definition can only appear once in a program, while declaration can appear multiple times.

• Example of function definition: ...read more

Swapping numbers without using a temporary variable

• Use addition and subtraction to swap the numbers

• Example: a = 5, b = 10. a = a + b (15), b = a - b (5), a = a - b (10)

• Alternatively, use bitwise XOR operation to swap the numbers

• Example: a = 5, b = 10. a = a ^ b (15), b = a ^ b (5), a = a ^ b (10)

This program generates a Fibonacci series up to a given length.

• Use an array to store the Fibonacci series

• Initialize the first two elements of the array as 0 and 1

• Use a loop to generate the subsequent elements of the series

• Stop the loop when the desired length is reached

Data types are classifications of data that determine the type of values that can be stored and manipulated. Pointers are variables that store memory addresses.

• Data types include integers, floating-point numbers, characters, and booleans.

• Pointers are used to store memory addresses of variables or objects.

• Example: int num = 10; int *ptr = # // ptr stores the memory address of num
