Array in c programming
This document discusses arrays in C programming. It defines an array as a collection of the same type of data elements stored in contiguous memory locations that are accessed via an index. It provides the syntax for declaring a 1-dimensional array, which specifies the type, array name, and number of elements. An example declares and initializes an integer array of size 5. The document also shows examples of summing the elements of a hardcoded and user-input array using indexing and loops.

This slide introduces the concept of arrays in C programming as a data structure.
Shows array element indexing with an example of an array of integers, demonstrating a collection of the same data type.
Explains the syntax for declaring an array, specifying type, name, and size. Mentions that array size must be an integer constant.
Continues explaining array declarations and illustrates an example of a one-dimensional array with its structure.
Demonstrates how to calculate the sum of static integer values both individually and through an array with expected output.
Shows how to calculate the sum of numbers in an array using user input, utilizing loops for input and summation.
Lists the names and IDs of the individuals involved in the presentation, along with their academic details.

The size of the array is indicated by <array_size>, the number of elements in the array. <array_size> must be an int constant or a constant expression.
