How to Iterate Over a Set in C++ ?

Answer

To iterate over a set in C++, you can use a range-based for loop.

✐ Examples

1 Iterate Over Set of Strings

In this example,

We create a set of strings named stringSet containing various strings.
We use a range-based for loop to iterate through each element in the stringSet.
Within the loop, we perform a specific operation or print each string element.

C++ Program

#include <iostream>
#include <set>

int main() {
    std::set<std::string> stringSet = {"Apple", "Banana", "Orange"};
    for (const std::string& str : stringSet) {
        std::cout << str << std::endl;
    }
    return 0;
}

Output

Apple
Banana
Orange

2 Iterate Over Set of Integers

In this example,

We define a set of integers named intSet containing various integer values.
We use a range-based for loop to iterate through each element in the intSet.
Within the loop, we perform a specific operation or print each integer element.

C++ Program

#include <iostream>
#include <set>

int main() {
    std::set<int> intSet = {1, 2, 3, 4, 5};
    for (int num : intSet) {
        std::cout << num * 2 << std::endl;
    }
    return 0;
}

Output
