C++ 读写文件安全又简洁的简单实例

实例代码：

#include <string> #include <iostream> #include <fstream> using namespace std; int get_file_content(string sFileName, string& sFileContent); int main(int argc, char* argv[]) { string sFileContent; get_file_content("./test", sFileContent); cout << sFileContent << endl; return 0; } int get_file_content(string sFileName, string& sFileContent) { ifstream ifs (sFileName.c_str(), ifstream::in); sFileContent.clear(); char c; while (ifs.get(c)){ sFileContent.append(1, c); } ifs.close(); return 0; } int set_file_content(string sFileName, string& sFileContent) { ofstream ofs(sFileName.c_str(), ofstream::binary); size_t nCount = sFileContent.size(); ofs.write (sFileContent.c_str(), nCount); ofs.close(); return nCount; }
