int numdigits(int num){

int len = 0;

while(num >= 10){
num = num/10;

return len;

This algorithm is used to count the number of digits but I can't understand it.
Someone explain it to me please :D


Add print statements after each line to print out the values that were set/changed on that line. Then you'll be able to understand how it works.
