A string is a series of characters treated as a single unit. A string may include letters, digits and various special characters written in double quotation marks: “Aurora Alvarado”

Strings are like arrays, because an array name is also a constant pointer to its first element. 

A string can be stored in an array using steam extraction with cin:

cin >> word;

The string entered by the user is stored in word.

The if, if...else and nested if...else statement are used to make one-time decisions in C++ Programming, that is, to execute some code/s and ignore some code/s depending upon the test condition. Without decision making, the program runs in similar way every time. 

The if statement checks whether the test condition is true or not. If the test condition is true, it executes the code/s inside the body of if statement. But it the test condition is false, it skips the code/s inside the body of if statement.

The if keyword is followed by test condition inside parenthesis ( ). If the test condition is true, the codes inside curly bracket is executed but if test condition is false, the codes inside curly bracket { } is skipped and control of program goes just below the body of if as shown in figure above.

I found the code shown in the picture in http://www.tutorialspoint.com/cplusplus/cpp_nested_if.htm and information in http://www.programiz.com/cpp-programming/if-else 

Just simple conditionals!
