11.11. Mixed-Up Code Exercises¶

Answer the following Mixed-Up Code questions to assess what you have learned in this chapter.

Suppose you run Club Keno, and you are in charge of picking the 20 random numbered balls between 1 and 80. Construct a block of code that chooses these random numbers, then saves them to a vector called <code>keno</code>.

        std::vector keno;
---
std::random_device device;
---
std::default_random_engine eng(device());
---
for (int i = 0; i < 20; ++i) {
---
 int x = std::uniform_int_distribution {1, 81} (eng);
---
 keno.push_back(x);
---
}
---
for (int i = 0; i <= 20; ++i) { #distractor
---
 int x = std::uniform_int_distribution {0, 80} (eng); #distractor
---
 keno.push_back(i); #distractor
