C++stl标准库手册

用来查找算法 如 istream::read // read a file into memory #include <iostream> #include <fstream> using namespace std; int main () { int length; char * buffer; ifstream is; is.open ("test.txt", ios::binary ); // get length of file: is.seekg (0, ios::end); length = is.tellg(); is.seekg (0, ios::beg); // allocate memory: buffer = new char [length]; // read data as a block: is.read (buffer,length); is.close(); cout.write (buffer,length); delete[] buffer; return 0;
