How to create a Set of size N in C++ - Step by Step Examples
How to create a Set of size N in C++ ?
Answer
In C++, sets can be represented using arrays or the standard library's std::set
container. To create a set of size N with different types of items using arrays, you can use arrays with unique elements.
✐ Examples
1 Create Set of Size N with Strings
In this example,
- We create an array named
stringSet
with initial string elements. - We ensure that the array contains unique elements to represent a set.
- The number of elements in the array determines the size of the set.
C++ Program
#include <iostream>
#include <string>
int main() {
std::string stringSet[] = {"apple", "banana", "cherry"};
int size = sizeof(stringSet) / sizeof(stringSet[0]);
std::cout << "Size of stringSet: " << size << std::endl;
return 0;
}
Output
Size of stringSet: N
2 Create Set of Size N with Integers
In this example,
- We create an array named
intSet
with initial integer elements. - We ensure that the array contains unique elements to represent a set.
- The number of elements in the array determines the size of the set.
C++ Program
#include <iostream>
int main() {
int intSet[] = {1, 2, 3};
int size = sizeof(intSet) / sizeof(intSet[0]);
std::cout << "Size of intSet: " << size << std::endl;
return 0;
}
Output
Size of intSet: N
Summary
In this tutorial, we learned How to create a Set of size N in C++ language with well detailed examples.
