How to convert string to byte array in C++

Answer 1

#include <iostream>
#include <string>
#include <cstring>

int main() {
    std::string str = "C++ Programming";
    size_t size = str.size();
    
    // Dynamically allocate memory for the byte array
    unsigned char* byteArray = new unsigned char[size];

    std::memcpy(byteArray, str.c_str(), size);

    for (size_t i = 0; i < size; i++) {
        std::cout << static_cast<int>(byteArray[i]) << " ";
    }

    // Free the allocated memory
    delete[] byteArray;
}
