### Section 3.15: Character Operations

#### Challenge Activity: 3.15.1 String with Digit

**Objective:**
Set `hasDigit` to true if the 3-character `passCode` contains a digit.

**Instructions:**
Complete the given C program to meet the specified objective. You need to write the logic that will determine if the `passCode` contains any digit character.

Here is the initial code provided for you:

```c
#include <stdio.h>
#include <string.h>
#include <stdbool.h>
#include <ctype.h>

int main(void) {
bool hasDigit;
char passCode[50];

hasDigit = false;
scanf("%s", passCode);

/* Your solution goes here */

if (hasDigit) {
printf("Has a digit.\n");
}
return 0;
}
```

**Steps to Follow:**

1. **Input Reading:**
The input `passCode` is read using `scanf`.

2. **Initialize `hasDigit`:**
Set the `hasDigit` variable to `false`.

3. **Logic Insertion:**
Insert logic to traverse the characters of `passCode` and set `hasDigit` to `true` if any character is a digit.

4. **Output:**
Print "Has a digit." if `hasDigit` is `true`.

- **Running the Program:**
Press the "Run" button to execute the program and verify the output.

#### Example: Checking for Digit

Consider the following `passCode` input: `abc123`
- The logic should properly identify that it contains digits.

#### Challenge Activity 3.15.2: Alphabetic Replace

**Objective:**
Replace any alphabetic character with `_` in a 2-character string `passCode`.

**Instructions:**

1. **Initialize:**
Read the `passCode` consisting of exactly 2 characters.

2. **Implementation:**
Use conditional statements to check each character of `passCode` using `isalpha()`. Replace alphabetic characters accordingly.

Example:
- Input: `9a`
- Output: `9_`

Please note that these challenge activities are crucial for understanding character operations in C, which is an essential skill in programming.
