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 ().

fix:

#include

#include

#include

using namespace std;

int main () {

string passCode;

cin >> passCode;

/ * Your solution goes here * /

cout << passCode << endl;

return 0;

}

Code which is pasted in the place of " / * Your solution goes here * / ":

if (isalpha (passCode[0])) / / if statement for the first character of the passcode string.

passCode[0]='_';

if (isalpha (passCode[1])) / / if statement for the second character of the passcode string.

passCode[1]='_';

Output:

If the user gives input as '4h', then it will prints '4_'. If the user gives input as 'a8', then the output is '_8'.

Explanation:

Missing information:

There is a three header file missing in the question programming code which names as the "cctype", 'iostream', 'cstring'.

Code Explanation:

The above code is in c+ + programing language, which is pasted on the place of " / * Your solution goes here * / ", which is written in the question part. The first if-statement checks the first character of the string that it is a charter or not if it is a character then replace the character with an underscore. The second if-statement is used to check the second character of the staring that is it a character or not if it then replaces the character with an underscore.
