I need some help. Trying to study.

(10 Pts) Given the function definition below, what will the following code display? int num1 = 0, num2=1654893; cout << num1 << << num2 << endl; num1 = getLast(num2); cout << num1 << << num2 << endl; // program continues int getLast(int num2) { num2%=10; return num2; }

0 1654893 1 1654893

Syntax error. The function is trying to return num2 and put it into num1!

0 1654893 3 1654893

0 1654893 1654893 1654893

Question 225 pts

(25Pts)Pick the best answer to accomplish the following task:

Write a function to accept a vector of ints and an int value, n. The function should double the value at location n in the vector, and then triple every value from n+1 to the end. There was code in main to ensure that n is less than the size of the vector.

void fixem(vector &V, int n) { V[n]*=2; for(int i=0,i

void fixem(vector &V, int n) { V[n]*=2; for(int i=n+1,i

void fixem(vector &V, int n) { V[n]*=2; for(int i=n+1,i

void fixem(vector V, int n) { V[n]*=2; for(int i=n+1,i

Write a bool function, areSame, to accept two vectors of ints and return true if the two vectors contain the same values in every cell. . The vectors are the same size. Efficiency counts!

bool areSame(const vector &V1, const vector &V2) { bool OK = true; int i=0; for(int i=0; i < V1.size());i++) { if(V1[i] != V2[i]) OK = false; } return OK; }

bool areSame(const vector &V1, const vector &V2) { bool OK = false; int i=0; while(OK && i < V1.size()) { if(V1[i] == V2[i]) i++; else OK = true; } return OK; }

bool areSame(const vector &V1, const vector &V2) { bool OK = true; int i=0; while(OK && i < V1.size()) { if(V1[i] == V2[i]) i++; else OK = false; } return OK; }

(25 Pts)Choose the best answer:

Write a function to accept a vector of ints and an empty vector of bools. For each value in the vector of ints which is even, it should set the corresponding cell in the vector of bools to true. All others should be false.

void AreOK(vector V1, vector V2) { for(int i=0;i else V2.push_back(true); } }

void AreOK(const vector &V1, vector &V2) { if(V1 %2 ==1) V2=false; else V2=true; } }

void AreOK(const vector &V1, vector &V2) { for(int i=0;i else V2[i]=true; } }

void AreOK(const vector &V1, vector &V2) { for(int i=0;i else V2.push_back(true); } }

Question 920 pts

(20 Pts) Select the best solution:

Write a function that will accept an empty vector of ints and an int and will fill the vector with the ulam sequence beginning with the int. You may assume that the int is greater than 2.

vector &V; int start) cout << "Enter starting number" << endl; cin >> start; V.push_back(start); while(start > 1) { if(start %2 ==0) start /=2; else start = start * 3 + 1; V.push_back(start);

void ulam(vector &V, int start) { V.push_back(start); while(start > 1) { if(start %2 ==0) start /=2; else start = start * 3 + 1; V.push_back(start); } }

void ulam(vector &V, int start) { for (i=start;i>1;i+=(i%2) { if(start %2 ==0) i /=2; else i = start * 3 + 1; V.push_back(i); } }

void ulam(vector &V, int start) { V.push_back(start); while(start > 1) { if(start %2 ==1) start /=2; else start = start * 3 + 1; V.push_back(start); } }
