How to split a string into fixed length chunks in C++

Answer 1

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

std::vector<std::string> split_string_into_chunks(std::string str, std::vector<std::string> &chunks, int length) {
    for (size_t i = 0; i < str.length(); i += length) {
        chunks.push_back(str.substr(i, length));
    }
    
    return chunks;
}    
int main() {
    std::string str = "java c++ c python c#";
    int length = 5;
    std::vector<std::string> chunks;
    
    split_string_into_chunks(str, chunks, length);
    
    for (size_t i = 0; i < chunks.size(); ++i) {
        std::cout << chunks[i];
        if (i < chunks.size() - 1) {
            std::cout << ", ";
        }
    }
}
