Question

c++ coding, find function

 

**Problem 4: StartsWith Function**

Write a function called `startsWith`. The function has two integer parameters that are both positive. It determines whether the second number starts with the first number. For example, the number 19683 starts with 196 and with 19683, but it does not start with 197 or with 196830.

Your function can return any answer of your choice in case either parameter is not positive. Excessively long solutions that use more than 8 lines of code may lose points.

**Example Usage:**

A sample program that uses the `startsWith` function is provided below:

```cpp
int main() {
    cout << startsWith(7, 747) << endl;  // prints true
    cout << startsWith(74, 747) << endl; // prints true
    cout << startsWith(747, 74) << endl; // prints false
    return 0;
}
```

This program illustrates how the function determines the starting sequence of the numbers, printing "true" or "false" based on whether the first number is the leading sequence of the second number.
