cin.get()

[ardnax14]

how can i display the number of variables or character that the user input?

[Smac89]

parse the string

if it is a number, length of the number is log₁₀ (num) + 1

[buffbill]

You could use the length() or sizeof() functions.

[Disch]

do not use sizeof to determine string length. That's not what it does.

Give an example of what you would like counted for a more specific answer.
