How to create a List of size N in C++ - Step by Step Examples

How to create a List of size N in C++ ?

Answer

To create a list of size N in C++ using std::list, you can use the constructor that takes the initial size and default value as arguments.

✐ Examples

1 Create a List of Size N with Default Values

In this example,

We include the necessary header file .
We use the std::list constructor to create a list of size N with each element initialized to a default value.
Finally, we print the created list to standard output using a for loop.

C++ Program

#include <iostream>
#include <list>

int main() {
    int size = 5;
    int default_value = 0;
    std::list<int> mylist(size, default_value);
    std::cout << "List of size " << size << " with default values: ";
    for (int val : mylist) {
        std::cout << val << " ";
    }
    std::cout << std::endl;
    return 0;
}

Output

List of size 5 with default values: 0 0 0 0 0

2 Create a List of Size N with Specific Values

In this example,

We include the necessary header file .
We use the std::list constructor to create a list of size N with each element initialized to a specific value.
Finally, we print the created list to standard output using a for loop.

C++ Program

#include <iostream>
#include <list>

int main() {
    int size = 5;
    int specific_value = 1;
    std::list<int> mylist(size, specific_value);
    std::cout << "List of size " << size << " with specific values: ";
    for (int val : mylist) {
        std::cout << val << " ";
    }
    std::cout << std::endl;
    return 0;
}

Output

List of size 5 with specific values: 1 1 1 1 1
