Noexcept and Move Semantics

Medium Move Semantics

Solve in Playground →

Problem Statement

Write a C++ program emphasizing why move constructors and assignment operators should be marked `noexcept` for container reallocations.

Input Format

A single word string S.

Output Format

Print string from container reallocation.

Constraints

1 <= Length <= 50

Sample Input

NoexceptTest

Sample Output

NoexceptTest

Explanation

Marking move operations `noexcept` allows STL containers (like `std::vector`) to use move semantics during reallocations instead of fallback copying.

Starter Code

#include <iostream>
#include <vector>
#include <string>

int main() {
    std::string s;
    if (std::cin >> s) {
        // Write your vector push_back or reallocation logic here
    }
    return 0;
}
