Question:


Use the following C++ program to answer questions a – e. Given the following code:  1 #include 2 using namespace std; 3 void rollAgain(int &, int &, char); 4 int main() 5 { 6 int die1 = 4; 7 int die2 = 2; 8 char code = 'x'; 9 cout << code << ' ' << die1 << ' ' << die2 << ' ' << endl; 10 rollAgain(die1, die2, code); 11 cout << code << ' ' << die1 << ' ' << die2 << ' ' << endl; 12 if (die1 == die2) 13 cout << "DOUBLES!"; 14 else 15 cout << "KEEP TRYING!"; 16 system("PAUSE"); 17 return 0; 18 } 19 void rollAgain(int & one, int & two, char c) 20 { 21 one += 10; 22 if (c == 'x') 23 { 24 c = 'y'; 25 two = 2; 26 } 27 else 28 c = 't'; 29 }   a What is printed by the code above? EXPLAIN IT!!!! b Which line(s) contain function prototypes? c Which parameter(s) (from Line 10) are sent by value? Which parameter(s) (from Line 10) are sent by reference? What is the difference (value vs. reference)? d Which variable(s) are local to rollAgain()? e A student added the following function call to the program.                            rollAgain(4.5, 5.5, 2);             The compiler flagged this statement with an error message. WHY?

Answer:


Step 1

Solution of the given question is:-

Step 2

Initially to a is , a @ line #9, 4 a 14 2 (is printed) (is printed since value of die changed) @ line @ line is, KEEP TRYING

QUESTION 6 (a) The bar shown in Figure Q2(a) is subjected to tensile load of 150 Kn. If the stress in the middle portions is limited to 160 N/mm², determine the diameter of the middle portion. Find also the length of the middle portion if the total elongation of the bar is to be 0.25 mm. E E = 2.0 + 105N/mm². (12 marks) 150 KN 10 cm DIA 10 cm DIA 150 KN 45 cm Figure Q6(a) (b) A brass bar, having cross-section area of 900 mm², is subjected to axial forces as shown in Figure Q2(b), in which AB = 0.6 m, BC = 0.8 m, and CD = 1.0 m. Find the total elongation of the bar. E = 1.0 + 105N/mm2 . (8 marks) Page 4 of 5 B D 40 KN 70 KN 20 KN 10 KN Figure Q6(b) (TOTAL = 20 MARKS)

  Introduction To find incremental revenue and cost, we subtract Current revenue and cost from Projected revenue and cost. Answer Current Situation Projected Sales and Profit Incremental Revenues and Costs Total Revenue Php1,500,000 Php1,800,000 + Php3000,000 Variable Cost 575,000 425,000 - Php 332,000 Direct Fixed Costs 625,000 700,000 + Php 75,000 Indirect Fixed Costs 100,000 100,000 No change Profit Php 200,000 Php 575,000 + Php 375,000 Profit increases by Php 375,000, thus a new camera and coffee maker must be purchased.
