iostreamĀ is the header file which contains all the functions of program like cout, cin etc. and
#includeĀ tells the preprocessor toĀ includeĀ these header file in the program.
No u don't have to use it multiple times...
once included it will do it's job in a program
cout is console output
cin is console input. ... It is the predefined library function used for input and output also called as header files
