Replace any alphabetic character with '_' in 2-character string passCode. Ex: If passCode is "9a", output is: 9_ Hint: Use two if statements to check each of the two characters in the string, using isalpha(). #include <iostream>#include <string>#include <cctype>using namespace std; int main() {string passCode; cin >> passCode; /* Your solution goes here */ cout << passCode << endl;return 0;} Please help me with the character operations problem in C++.
