How to create a Set of Numbers from 1 to N in C++ - Step by Step Examples

How to create a Set of Numbers from 1 to N in C++ ?

Answer

To create a set of numbers from 1 to N in C++, you can use a loop to add elements to a set.


✐ Examples

1 Create a Set of Numbers from 1 to 5

In this example,

  1. We define a set numberSet to store the numbers from 1 to 5.
  2. We use a for loop to iterate from 1 to 5 and add each number to the set.

C++ Program

#include <iostream>
#include <set>

int main() {
    std::set<int> numberSet;
    for (int i = 1; i <= 5; ++i) {
        numberSet.insert(i);
    }

    std::cout << "Set of numbers from 1 to 5:\n";
    for (int num : numberSet) {
        std::cout << num << ' ';
    }

    return 0;
}

Output

Set of numbers from 1 to 5:
1 2 3 4 5

2 Create a Set of Numbers from 1 to 10

In this example,

  1. We define a set numberSet to store the numbers from 1 to 10.
  2. We use a for loop to iterate from 1 to 10 and add each number to the set.

C++ Program

#include <iostream>
#include <set>

int main() {
    std::set<int> numberSet;
    for (int i = 1; i <= 10; ++i) {
        numberSet.insert(i);
    }

    std::cout << "Set of numbers from 1 to 10:\n";
    for (int num : numberSet) {
        std::cout << num << ' ';
    }

    return 0;
}

Output

Set of numbers from 1 to 10:
1 2 3 4 5 6 7 8 9 10
