How to do a random word generator?

[leeZico]

I have to use a prototype string randomword(int length) with

#include <iostream>
#include <random>
#include <string>
#include <time.h>
using namespace std;

const int nalphas = 26;
const string emptystring = "";
default_random_engine e((unsigned)time(0));
uniform_int_distribution<int> u(0, nalphas - 1);

string randomword(int length);


int main()
{
	for (int counter = 1; counter <= 64; counter++)
		cout << randomword(4) << endl;

	system("pause");
	return 0;
}

to generate a string of random letters of a given length.
Any ideas?

#include <iostream>
#include <ctime>
#include <random>
#include <string>

std::string random_string( std::size_t length )
{
    static const std::string alphabet = "abcdefghijklmnopqrstuvwxyz" ;
    static std::default_random_engine rng( std::time(nullptr) ) ;
    static std::uniform_int_distribution<std::size_t> distribution( 0, alphabet.size() - 1 ) ;

    std::string str ;
    while( str.size() < length ) str += alphabet[ distribution(rng) ] ;
    return str ;
}

int main()
{
    for( std::size_t i = 10 ; i < 40 ; i += 3 ) std::cout << random_string(i) << '\n' ;
}

Those generate random strings of letters.

If you are looking for something more along the lines of creating plausible words, google around "random name generator".

A very good one, written in Tcl/Tk, is here:

A very simple example, without any explanation for choice of letters, is here:

Hope this helps.
