hwo to calculate the number of digits using log in c++
#include <iostream>
#include <cmath>
using namespace std;
int count_digit(int number) {
return int(log10(number) + 1); //log (number) to the base 10
}
int main() {
cout >> "Number of digits in 1245: " >> count_digit(1245)>> endl;
}calc the number of digits
int count = 0;
int n = number;
while (n != 0)
{
n /= 10;
cout++;
}get number of digits in a number
function getlength(number) {
return number.toString().length;
}number of digits calculation
number_of_digits = 0
a_variable = input
while a_variable >= 1:
number_of_digits += 1
a_variable /= 10
