Link BD consists of a single bar 30 mm wide and 12 mm thick. Knowing that each pin has a10 mm diameter, determine the maximum value of the average normal stress in the link BD if θ = 15 degrees.

Link will be apear in 30 seconds.

Well done! you have successfully gained access to Decrypted Link.

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?
