How to remove a random word from a string in C++

Answer 1

#include <iostream>
#include <sstream>
#include <vector>
#include <ctime>

std::string removeRandomWord(const std::string& input) {
    std::istringstream iss(input);
    std::vector<std::string> words;
    std::string word;

    // Split the input string into words
    while (iss >> word) {
        words.push_back(word);
    }

    // Seed the random number generator
    std::srand(std::time(0));

    // Generate a random index
    int randomIndex = std::rand() % words.size();

    // Remove the word at the random index
    words.erase(words.begin() + randomIndex);

    // Reconstruct the string without the random word
    std::ostringstream oss;
    for (size_t i = 0; i < words.size(); i++) {
        if (i != 0) {
            oss << " ";
        }
        oss << words[i];
    }

    return oss.str();
}

int main() {
    std::string str = "I'm not clumsy The floor just hates me";
    
    std::string result = removeRandomWord(str);
    
    std::cout << "str: " << str << std::endl;
    std::cout << "result: " << result << std::endl;
}
