$1.$ Write a C$++$ program that does the following:

a$.$ Create a C$++$ file with the name problem$2.$cpp$.$

b$.$ Write the function thirdDigit using recursion, which returns the third digit from the left of its positive integer parameter.

c$.$ If the parameter is less than $100,$ then the function returns $0$ because there is no third digit.

d$.$ Type in the following main function into your C$++$ program file:

int main$()$

$\{$

$$cout $<<$ thirdDigit$(347)<<""$;

$$cout $<<$ thirdDigit$(2048)<<""$;

$$cout $<<$ thirdDigit$(560125)<<$ endl;

$//$ This code should print:

$//740$

$$

$$return $0$;
