Computer Science I - Martin Hardwick Lecture 1 -- 2 Accessing one character in a string #include <iostream> #include <string> using namespace std; int main () { string word; cout << "Enter a word" << endl; cin >> word; if (word[0] == 'b') { cout << "You entered bang!" << endl; } else { cout << "You did not enter bang!" << endl; } return 0; } Word[0] gets the first character in the string Word[1] would get the second character Etc. What if I want to get each character in a string? I will need to know the number of characters Try typing “word.” in Visual C++ you should see a long list of methods. Now make a guess for a function that returns the character size

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
