In C programming, an array is a variable that can store multiple values in a single variable rather than having separate variables for each element. It is one of the simplest data structures where each data item can be accessed randomly using its index number. Arrays are used to store a collection of primitive data types like int, float, double, char, etc., as well as derived data types like structures and pointers.
The following section contains various C programs on Arrays with examples such as array operations, types of array, single-dimensional arrays, mathematical functions on arrays, sort, and merging operations. It also includes programs for inserting and removing elements from an array. Each sample program on the Array includes a program description, C code, and program output. All Array C examples have been compiled and tested on Windows and Linux systems.
Here is the listing of C programming examples on Array:
- C Programs on Largest & Smallest Numbers in an Array
