This is a C++ question and the development environment is Visual Studio 2015 Build the below program.

#include #include using namespace std; int main() { ofstream test1file("test1"); cout << "Text written: "; cout << "This text is written to file! "; //write to screen test1file << "This text is written to file! "; test1file.close(); ifstream tin("test1"); tin.seekg(10); cout << " Current position: " << tin.tellg() << " "; cout << " Content of the file after an offset of 10: "; char ch; while (tin.get(ch)) { cout << ch; } //display file tin.close(); return 0; }

Use seekp such that the word "written" in the file is replaced by "1234567".

Verify the result by using the DOS commands "dir" and "type test1" again.
