Finding a number at a particular digit in a number

Question

I want to get number present at the specific index.

Suppose the number is "123456789" and i need to return the number at position 3 from left.

Should I convert this number to a string and re-convert the char at specific index to integer to get the number value?

Is there any inbuilt function to do so in C++?

Answer 1

This should return the third digit that of a number!

cout << "Enter an integer";
int number;
cin >> number;
int n = number / 100 % 10

Or (for all digits):

 int number = 12345;
 int numSize = 5;
for (int i=numSize-1; i>=0; i--) {
  int y = pow(10, i);
  int z = number/y;
  int x2 = number / (y * 10);
  printf("%d-",z - x2*10 );
}
