generate() Function in C++

This C++ program demonstrates the generate() algorithm which saves the values generated by a function into a container. The program utilizes the generate() algorithm which takes three parameters – iterator to the beginning of the container, iterator to the end of the container and the generating function.

Here is the source code of the C++ program which demonstrates the generate() algorithm. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

    std::generate(v.begin(), v.end(), ret);

```
    std::cout << "Vector v : ";
```

    std::copy(v.begin(), v.end(), std::ostream_iterator<int>(std::cout, " "));

```
    std::cout << "\n";

$ gcc test.cpp
$ a.out
Vector v : 1 2 3 4 5 6 7 8 9 10
