How to Get Length of a List in C++ ?

Answer

To get the length of a list in C++, you can use the size() method of the std::list class.

✐ Examples

1 Get Length of an Integer List

In this example,

We create a list named numbers with integer values using std::list.
We use the size() method of the list object numbers to get the number of elements in the list.
The size() method returns the number of elements in the list.
Finally, we print the size to standard output.

C++ Program

#include <iostream>
#include <list>

int main() {
    std::list<int> numbers = {1, 2, 3, 4, 5};
    std::cout << "Length of the list is: " << numbers.size() << std::endl;
    return 0;
}

Output

Length of the list is: 5

2 Get Length of a String List

In this example,

We create a list named fruits with string values using std::list.
We use the size() method of the list object fruits to get the number of elements in the list.
The size() method returns the number of elements in the list.
Finally, we print the size to standard output.

C++ Program

#include <iostream>
#include <list>
#include <string>

int main() {
    std::list<std::string> fruits = {"apple", "banana", "cherry"};
    std::cout << "Length of the list is: " << fruits.size() << std::endl;
    return 0;
}

Output

Length of the list is: 3
