Algorithm and flow chart for bubble sort on an array

• Compare adjacent elements and swap if necessary

• Repeat until no more swaps are needed

• Time complexity: O(n^2)

• Space complexity: O(1)

Declaration is a statement that tells the compiler about the existence of a variable or function, while definition provides the actual implementation of the variable or function.

• Declaration introduces a name and its type to the compiler, while definition allocates memory for the variable or function.

• Declaration does not allocate memory, while definition does.

• Multiple declarations can exist for a single definition, but only one definition can exist for a single declaration.

Variables are containers that hold values or references to values in computer programs.

• Variables are used to store data in a program

• They can hold different types of data such as numbers, strings, and booleans

• Variables can be assigned values and their values can be changed throughout the program
