Combine Files
fstream is fast and is good for combining large files together without needing to read in each file.
Combine 2 files (can be any file type):
#include <fstream>
std::ifstream ifstream1("a.bin", std::ios_base::binary);
std::ifstream ifstream2("b.bin", std::ios_base::binary);
std::ofstream ofstream1("c.bin", std::ios_base::binary);
ofstream1 << ifstream1.rdbuf() << ifstream2.rdbuf();
Adding some bytes to the output file:
BYTE MyByteArray[3];
MyByteArray[0] = 0x01;
MyByteArray[0] = 0x02;
MyByteArray[0] = 0x03;
ofstream1.write((const char*)&MyByteArray[0], 3);
ofstream1.close();
Create a new text file from an existing text file and a string
#include <fstream>
std::ifstream ifstream1("some_existing_file.txt", std::ios_base::in);
std::ofstream output_file("my_new_file.txt"); //Will overwrite an existing file
output_file << ifstream1.rdbuf();
output_file << "My text to add";
output_file.close(); //(Not strictly necessary as it will get closed when output_file goes out of scope)
USEFUL?
