output format

[kev172006]

how do i decrease the digits of a number or round it down to a specific number of digits?

for example....

int n;
cin >> n;
cout << n << endl;

this will output whatever int is entered but what if i want the value to be no more than 7 digits how would i do this?

I'm sure you meant a float or double and not an integer because integers are already well-rounded and to limit an integer to less than 7 digits means you limit the integer to an integer less than 10,000,000
