What is the value of g(4), given the definition of g below? (Hint. Work out g(1), then g(2), then g(3), then g(4), in that order. Keep your work organized.)
int g(int n) { if(n == 1) return 2; else return g(n-1) + 3; }
Write a C++ definition of function sum(a,b) that returns a + (a+1) + ... + b. For example, sum(2,5) = 2 + 3 + 4 + 5 = 14. More precisely, sum(a,b) returns the sum of all integers that greater than or equal to a and less than or equal to b. For this question do not use any kind of loop. Use recursion instead.
Redo the previous exercise, but this time use a loop, not recursion.
What does jump( ) return, where jump is writtten below, using function jumpHelper?
void jumpHelper(int x) { x = x + 1; } void jump() { int z = 40; jumpHelper(z); return z; }
What does hop( ) return, where hop is writtten below, using function hopHelper?
void hopHelper(int& x) { x = x + 1; } void hop() { int z = 40; hopHelper(z); return z; }
What does romp( ) return, where romp is written below, using function rompHelper?
void rompHelper(int a, int& b) { b = a + 2; a = b + 1; } int romp() { int x = 4; int y = 25; rompHelper(x,y); return x + y; }
Which of the following will create an array of 30 integers called Orange in the run-time stack?
