Base C++ library :
#include <fstream> #include <string> #include <iostream> using namespace std; string file_get_contents(char* fileName) { ifstream file(fileName); if (!file) { return ""; } string content = "", line; while (!file.eof()){ getline(file,line); content += line+"\n"; } file.close(); return content; } void file_put_contents(char * fileName, char * content) { ofstream file; file.open(fileName); file << content; file.close(); } int main() { file_put_contents("temp.txt", "hello,world! for C++ \n"); cout << file_get_contents("temp.txt"); return 0; }
