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 3 using arr[3] and prints its value.
- Modifies the element at index 3 by assigning a new value (15) to arr[3] and prints the modified value.
C++
#include <iostream> using namespace std; int main() { int arr[5] = {1, 2, 3, 4, 5}; // Initialize an array // Access elements cout << "Element at index 3: " << arr[3] << endl; // Modify elements arr[3] = 15; cout << "Modified element at index 3: " << arr[3] << endl; return 0; } |
Output
Element at index 3: 4 Modified element at index 3: 15
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.
