Write a C function count digits(int num); where num is a positive integer. The function counts how many times each of the digits 0..9 appears in num, and prints the results in python code example
Example 1: how to find how many digits a number has in c++
#include <iostream>
#include <cmath>
unsigned int getNumberOfDigits (int i)
{
return i > 0 ? log10((double) i) + 1 : 1;
}
int main()
{
std::cout << "Number of digits: " << getNumberOfDigits(6738) << std::endl;
return 0;
}
Example 2: c how many digits has a number
digits = (number == 0) ? 1 : (log10(number) + 1);
while (number > 0)
{
number /= 10;
digits++;
}
