Is there a way that I can only use 1 digit of a variable instead of all of them?

Question

For example:

int example = 13;
int Numbers;
Numbers = example;
//is there a way that I can only have example's "3" set equal to Numbers? Instead of setting 13 equal to numbers.

Answer 1

Numbers = example % 10
This way numbers will be equal to 3
But if you wanna choose any digit from a number than you can convert it to a string and then choose by index

Answer 2

int a = 34;
string b = to_string(a);
cout << b[0] << b[1];
// or
cout << b.at(0) << b.at(1)

Answer 3

If you know the number u really want to make use of.

Let's say u want to make use of the last digit,

u can do something like this

int example = 13;
int Numbers = example%10;

Note the module operator which returns the remainder which in our case will be the last digit (3)

But let's say you want to use a digit in between some numbers, all u have to do is convert to string, using indexing, get your value and convert to int

Let's take 1673 as the number, and u need the digit 7*

Your code should look like this

int userNumber = 1673

string desiredDigit = to_string(userNumber); // converting the int to string..... Remember to #include <string> so as to make use of the string methods.

desiredDigit = desiredDigit.at(2);

converting back to int

int luckyNumber= stoi(desiredDigit);

cout << "Value of Lucky Number ==" <<luckyNumber

I hope this helps

Happy Coding
