Implementation of array in C
- Declares an integer array arr with a size of 5 and initializes it with values.
- Accesses the element at index 2 using arr[2] and prints its value.
- Modifies the element at index 2 by assigning a new value (10) to arr[2] and prints the modified value.
C
#include <stdio.h> int main() { int arr[5] = {1, 2, 3, 4, 5}; // Initializing an array with values // Accessing elements printf ("Element at index 2: %d\n", arr[2]); // Modifying elements arr[2] = 10; printf ("Modified element at index 2: %d\n", arr[2]); return 0; } |
Output
Element at index 2: 3 Modified element at index 2: 10
Implement Arrays in different Programming Languages
Arrays are one of the basic data structures that should be learnt by every programmer. Arrays stores a collection of elements, each identified by an index or a key. They provide a way to organize and access a fixed-size sequential collection of elements of the same type. In this article, we will learn about the basic use of array in most common languages like C, C++, Java, Python, etc.
