Question

Need a c++ program to generate a random string of letters between 8 and 16 characters.

Answer 1

C++ code for the given problem statement:

#include <bits/stdc++.h> 
using namespace std; 
  
const int MAX = 26; 
  
// Returns a string of random alphabets of 
// length between 8 to 16 characters
string printRandomString() 
{   int num = (rand() % (16 - 8 + 1)) + 8; 
    char alphabet[MAX] = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 
                          'h', 'i', 'j', 'k', 'l', 'm', 'n',  
                          'o', 'p', 'q', 'r', 's', 't', 'u', 
                          'v', 'w', 'x', 'y', 'z' }; 
  
    string res = ""; 
    for (int i = 0; i < num; i++)  
        res = res + alphabet[rand() % MAX]; 
      
    return res; 
} 
  
// Driver code 
int main() 
{ 
   srand(time(NULL)); 
   cout << printRandomString(); 
   return 0; 
}
