// how to answer this question in C++ with the following ?

//Write a function that generates a string of random letters of a given length. The function's prototype is

//string randomword(int length);

//where n is the string's length. The function makes sure that its parameter is a non-negative integer.

//Write program to test the function.

#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;

}

string randomword(int length)

{

string rstring = emptystring;

return rstring;

}

Explanation / Answer

In C++:

void gen_random(char *s, const int len) {
static const char alphanum[] =
"0123456789"
"ABCDEFGHIJKLMNOPQRSTUVWXYZ"
"abcdefghijklmnopqrstuvwxyz";

for (int i = 0; i < len; ++i) {
s[i] = alphanum[rand() % (sizeof(alphanum) - 1)];
}

s[len] = 0;
}

This is C code but this will make your answer I hope
static char *rand_string(char *str, size_t size)
{
const char charset[] = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJK...";
if (size) {
--size;
for (size_t n = 0; n < size; n++) {
int key = rand() % (int) (sizeof charset - 1);
str[n] = charset[key];
}
str[size] = '';
}
return str;
}
