1. Using string type variables
Section day 1
Using string type variables

2. The ASCII Character Set
41 = ')'

3. Using string: Input and Output
#include <iostream>
#include <string>
using namespace std;
int main() {
string name;
cout << "Enter your name: ";
cin >> name;
cout << "Your name is " << name << endl;
return 0; }
>> reads a word up to a space or newline character
Type the above code into a new project. The next slide will
tell us what else we need to do before compilation.

4. Using string: getline
#include <iostream>
#include <string>
int main() {
string name;
cout << "Enter your full name: ";
getline(cin, name);
cout << "Your full name is " << name << endl;
return 0; }
getline reads an entire line, including blanks, up to
a newline character

5. Using >> Before getline
#include<iostream>
#include<string>
// program segment below
string name;
int age;
cout << "Enter your age: ";
cin >> age;
cout << "Enter your full name: ";
getline(cin, name);
cout << "Your age is " << age << endl;
cout << "Your full name is " << name << endl;
Do you see any problems with this segment of code?
Type and run a program that includes this segment.
getline encounters the trailing newline after the age,
stores an empty string in name, and does not wait for user input

6. Reverse the order of the inputs, with getline being called before >>.
apstring name;
int age;
cout<<"Enter your full name:";
getline(cin,name);
cout<<"Enter your age:";
cin>>age;
cout << name << “,you are ”<<age<<endl;

7. Or use cin.ignore(); before getline
#include <iostream>
#include <string>
string name;
int age;
cout << "Enter your age: ";
cin >> age;
cin.ignore(); // consume \n
cout << "Enter your full name: ";
getline(cin, name);
cout << "Your age is " << age << endl;
cout << "Your full name is " << name << endl;

8. Memory for String Variables
When a string variable is declared, no memory is initially provided.
When a value is assigned to a string variable, the computer automatically adjusts the memory to accommodate the number of characters to be stored.

9. apstring Member Functions

10. Group Activity
Write a program that will prompt the user for the name of the school and save it into a single variable of the string data type.
Your program will output the users school name and the string length as you see below:
Your school name is NA Intermediate High School.
There are 27 characters in this name.
(including space characters)
Raise your hand when your program functions properly.
