randomly reverse two selected words

[komrad]

I need to write a code which a class named String defined with data member sentence(char) which has two member functions:
1)to read the sentence (input)
2)to randomly select two words from the sentence and reverse them

eg if i give an input as "my name is komrad"
possible output can be: eman darmok

I have no clue how to go about this...please help

Thanks in advance.

At First, tokenize(decompose ) sentence into words
You can use
string::find_first_of
for it.
After that , use STL functions.
First use random_shuffle for randomly shuffling words. Or you can generate 2 random numbers by using rand() function.

Later , reverse them with STL function reverse

Thank you Dufrense for your prompt reply. I am a beginner in C++. could you kindly provide a sample code as to how to implement this?

Do you mean something like this:

class String
{
    // data members
    char * sentence;
public:
    // default constructor
    String() {
        /* TODO */
    }
    // copy constructor
    String( const String & s ) {
        /* TODO */
    }
    // assignment operator
    String & operator=( const String & s ) {
        /* TODO */
    }
    // destructor
    ~String() {
        /* TODO */
    }

    // method to read in a sentence
    void input() {
        /* TODO */
    }
    // method to select two words from sentence, reverse, and output them
    void output() const {
        /* TODO */
    }
};

That should get you started, if I understood the question correctly.

Not meaning to be snotty, but if you actually have no idea how to go about this, you should probably start with something less ambitious.
