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 : #include #include #include using namespace std; int main() {string passcode; cin > > passcode; /* your solution goes here */cout < < passcode < < endl; return 0; }

To change the characters of a string, we simply iterate through the string. The index character of a string starts from 0 while the last character is n - 1.

Replace /*Your solution goes here */ with the following lines of code, where comments are used to explain each line.

//This checks if the first character of passCode is an alphabet

if(isalpha(passCode[0])){

If yes, the first character is updated to _

passCode[0] = '_';

}

//This checks if the second character of passCode is an alphabet

if(isalpha(passCode[1])){

If yes, the second character is updated to _

passCode[1] = '_';

}
