1.1 Arrays in Data Structure | Declaration, Initialization, Memory representation
Jenny's Lectures CS IT・2 minutes read
Arrays in C language are essential for storing multiple values under one variable name, with three types available and the requirement for elements to be of the same data type. Accessing array elements involves calculating addresses based on the base address, index value, and data type size, allowing for constant time data retrieval.
Insights
- Arrays in programming store multiple values under a single variable name, streamlining data management by avoiding the need for multiple individual variables.
- Different types of arrays, such as one-dimensional, two-dimensional, and multi-dimensional, exist in C language, each requiring elements of the same data type and fixed sizes, with elements stored in consecutive memory locations for efficient data retrieval.

Recent questions
What is the purpose of arrays in programming?
Arrays are used to store multiple values under one variable name, eliminating the need for numerous individual variables.
How are arrays declared in the C language?
In C, array declaration involves specifying the data type, array name, and constant size within brackets.
What are the different types of arrays?
There are three types of arrays: one-dimensional, two-dimensional, and multi-dimensional arrays.
Can arrays be resized during runtime?
Arrays are fixed in size and cannot be altered during runtime.
How are array elements accessed in programming?
Accessing array elements requires calculating the address using the base address, index value, and size of the data type, allowing for constant time access once the base address is known.
