Answer 1

printf() is a function, cout is a global object of std.

Answer 2

**cout
it means write to screen whatever is there..

**printf()
f stand for format/formatter
that is... you can leave for strings and add them as parameters..

eg
x = "string"
printf("this is %s.",x)

that will output "this is string"

printf helps you when you have values already in variables or else you would have to do it "this is "+x ....it saves the trouble of adding +s
