Read in a 3-character string from input into variable passCode. Declare a boolean variable isValid and set isValid to true if the first and third characters of passCode are both digits. Otherwise, set isValid to false. Ex: If the input is 6c6, then the output is: Valid passcode Note: Use getline(cin, passCode) to read the entire line from input into passCode. One pint equals 16 fluid ounces. The following program converts a volume in fluid ounces to pints and then outputs the volume in ints. The code contains errors. Find and fix the errors. Ex: If the input is 2.0, then the output is: .125 pints 1 \#include 2 \#include \#include using namespace std; int main() \{ /* Modify the following code */ int volumeOunces; int volumePints; cin >> volume0unces; volumePints = volume0unces /16
