Lab 1 Prelab Questions

1. What line of code is necessary to use data types and functions from the standard libraries without prepending "std::" to every piece of code referring to them?

using namespace std;

2. Declare a vector of integers with space for 10 elements.

vector<int> vecint(10);

3. What function will add an element to the end of a vector?

vecname.push_back(element);

4. Show how to use cout.
5. Show how to use cin.
6. Can you compare a string and an integer?
7. Does -1 equal "-1" in C++?
8. Write code to store user input in a vector of strings up until the stop word "stop".

vector inpvec;
string inp;
cout << "Enter Input:" << endl;
cin >> inp;
while (inp != "stop")
{
	inpvec.push_back(inp);
	cin >> inp;
}

9. Create a for loop to output every element from a vector of strings called strvector.

for (int i = 0; i < static_cast<int> strvector.size(); i++)
{
	cout << strvector[i];
}

10. Why will the following code cause a segmentation fault?

for (unsigned int i = vec1.size()-1; i >= 0; i--)
	cout << vec1[i] << endl;
