C++ Introduction

StringString

You can also store text in variables, in addition to symbols using char. For this, you need to:

  • Connect the string file
  • Use std scope resolution
  • Declare a variable of type string
cpp

main.cpp

Strings variables can also contain numbers (as text):

cpp

main.cpp

If you try to add two string variables, you get a concatenation (it works without spaces):

cpp

main.cpp

The same thing will happen with numbers – they will not be added algebraically.
