C++ Array Assignment

Today, we will learn C++ Array Assignment. We can assign multiple values to C++ Arrays. There are many ways you can initialize a C++ array. You can create different datatypes of arrays in C++ e.g. string, int, etc are the two most common types of C++ arrays that are commonly used. Today, we will see how to initialize and assign values to C++ arrays. Let’s start.

Declaring Empty C++ Array

We can declare an empty array in C++ using square brackets and specifying the number of items.

string city[5];
int id[6];

Declaring and C++ Array Assignment

We can declare and initialize a C++ Array at the same time. To initialize a C++ Array while declaring, we can use curly brackets and then values inside curly brackets.

string city[5] = {"Agra", "Delhi", "Noida", "Gurgaon", "Banglore"};

Accessing the elements of the C++ Array

You can use square brackets to access the elements of the C++ Array. Inside square brackets, use the index number of the element you want to access. Indexing in C++ starts from 0.

cout << city[0];
// Outputs Agra

Looping a C++ Array

#include <iostream>
#include <string>
using namespace std;
int main() {
string city[5] = {"Agra", "Delhi", "Noida", "Gurgaon", "Banglore"};
for(int i = 0; i < 5; i++){
    cout << city[i] << "\n";
}
  return 0;
}

Output:
