Question

• Define a std::vector<int> variable v and add 15 random integers into that container. Use the <random> header file and the “uniform_int_distribution” to generate values between 1 and 100, inclusive. <random> is available only in C++11 and newer. If you prefer, you can use floating-point values instead of ints, in that case, look up uniform_real_distribution -- if you decide to do that, use float or double instead of int in all subsequent parts of the lab.
• Write a print function that accepts const std::vector<int> & and prints the elements of the vector, using the iterator std::vector<int>::const_iterator. For this function, you should not use the index operator [] directly (when using a for loop, the performance of the iterator is typically better than the [] operator - why? Optionally, measure the time each approach takes (using [] or iterators) -- note that you may have to add an extra outer loop to repeat this many times since timing short runs is inaccurate; refer to the chrono documentation and examples).
• Print the random values of the vector v, using your previously-defined function.

Answer 1

Below is the C++ code I hope that i have provided sufficient comments for your better understanding Note that I have done proper indentation but this code is automatically left alligned on this interface

#include <iostream>
#include <chrono>
#include <random>
using namespace std;
int main ()
{
vector <int>v;
vector <int>::iterator it;
int temp;
unsigned seed = chrono::system_clock::now().time_since_epoch().count();
minstd_rand0 generator (seed);
for(int i=1;i<=15;i++)
{
temp = generator()%100+1; //generates random number from 1 to 100
v.push_back(temp);
}
cout<<"Vector contains: ";
for(it = v.begin(); it != v.end(); it++)
{
cout<<*it<<" ";
}
cout<<endl;
return 0;
}

Below is the screenshot of output

I have tried to explain it in very simple language and I hope that i have answered your question satisfactorily.Leave doubts in comment section if any.
