Guys a little help here please

[Sarmadas]

i want to write a function which take an intiger and return the number of the of digits in it i.e

int i = 123456
func(i)
{
some code
}

output

the number of the digits are 6

[theranga]

do you know what a logarithm is?

[Sarmadas]

no i don't know

[Disch]

hint:

int i = 123456;

i /= 10;  // divide by 10

cout << i;  // notice that you just "chopped a digit off" of i 

[Sarmadas]

what if i enter 12584585 now this won't work hmmm

You can use the modulo operator ('%'). For example:

int i = 12345;

i %= 10;

i will be equal to 5

yes i know but what if user enter 845769
now it will return 9
but i want it to return 6

[Hippogriff]

int x = 542334;
int Amount = 0;

while(x > 0)
{
	x /= 10;
	Amount++;	
}

cout << Amount << endl;

This should work.

Modulo is not what you want. Modulo by 10 just gives you the last digit.

It's a simple pattern here: Dividing by 10 chops off a digit. So just count how many digits you have to shop off until you get them all.

It'll involve a loop.

give me a example of code please
