Lab #1 Using a vector of strings to store a source code program

Refresh your memory by reading the related sections in C++ Primer and the online MSDN document on the member functions of STL vector class. Create a C++ project and in the main function to work on the vector class to do things as described in the following.

Task #1: Manually store 3 lines of source code in a vector of strings

• Declare a vector of strings and name it myVect. Use the push_back method of the vector class to store the following three strings into myVect:

• "radius=2; ",
• "area=3.14*radius*radius;" and
• "display area;" .

Task #2: Assess the elements by their indices

• Write a loop to display all the elements myVect[i] in myVect one by one.

Task #3: Assess the elements using an iterator

• Write a loop using a vector<string>::iterator iterator to iterate through the vector myVect and to display all the elements in myVect one by one.

Task #4: Use an iterator to delete some contents

• Call the erase method to delete the second element in myVect. (i.e. delete myVect[1] from the vector)
• Check the new contents: Write a loop using a vector<string>::iterator iterator to iterate through the vector myVect and to display all the elements in myVect one by one.

Task #5: Use an iterator to insert new contents

• Call the insert method of the vector class to insert a new string "display radius;" right before the element currently holding "display area;" in myVect.
• Check the new contents: Write a loop using a vector<string>::iterator iterator to iterate through the vector myVect and to display all the elements in myVect one by one.

Task #6: Clear the contents of the entire vector

• Call the clear method to clear the vector myVect into an empty vetor.
• Check the new contents: Write a loop using a vector<string>::iterator iterator to iterate through the vector myVect and to display all the elements in myVect one by one.

Task #7: Use getline to read an arbitrary number of lines of source code into a vector of strings

• Declare a string object s and then write a loop which on each iteration (i) calls getline(cin, s) to read in a line into s, (ii) if the contents of s is neither an empty string nor the special string ".", calls the push_back method to store it in the end of the vector myVect,and (iii) the loop will terminate if the contents of s is special string "."
• Check the new contents: Write a loop using a vector<string>::iterator iterator to iterate through the vector myVect and to display all the elements in myVect one by one.
