FILL IN THE BLANK QUESTIONS

8 (5 pts) Fill in the blank below to rewrite the statement shown using the conditional operator (?:). The same assignment must happen if( y > 12 ) x = 13; else x = 14;

Rewritten using the conditional operator:

x = (y > 12) ? 13 : 14;

9 (15 pts) Given:

int bar( int& some, int& other ) { cout << "bar\n"; some = other * 2; other = 3; return 100; other = 77;

} void foo( int first, int & second ) { cout << "foo\n"; first = 5; second = first + bar( first, second ); }

This code compiles and runs. Use it as it is written.

What is the output of this code? int j = 6, k = 3; cout << j << " , " << k << endl; foo( j, k ); cout << j << " , " << k << endl;

Write your answer here:

6 , 3 foo bar 6 , 106
