Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, 1-405 services 1-5, and 1-290 services 1-90. Note: 200 is not a valid auxiliary highway because 00 is not a valid primary highway number. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 the output is: I-90 is primary, going east/west. Ex: If the input is: 290 the output is: I-290 is auxiliary, serving I-90, going east/west. Ex: If the input is: 0 or any number not beween 1 and 999, the output is: 0 is not a valid interstate highway number. Ex: If the input is: 200 the output is: 200 is not a valid interstate highway number. 1 #include 10 11 int main(void) { int highwayNumber; scanf("%d", &highwayNumber); /* Type your code here. */ return 0;

Max Function
Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.
Power Function
A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:
Question
C Language - Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west.
Transcribed Image Text:**Understanding U.S. Interstate Highways Numbering: A C Programming Exercise**
The U.S. interstate highways have a systematic numbering convention to help travelers navigate efficiently. Here's a brief on how highways are numbered:
1. **Primary U.S. Interstates (Numbered 1-99)**:
- **Odd Numbers**: These interstates (e.g., I-5, I-95) typically run north/south.
- **Even Numbers**: These interstates (e.g., I-10, I-90) typically run east/west.
2. **Auxiliary Highways (Numbered 100-999)**:
- These highways serve the primary interstates and can be identified using the rightmost two digits of their numbers:
- Example: I-405 services I-5 and I-290 services I-90.
- Note: Highway numbers like 200 are not valid auxiliary highways if ‘00’ is not a valid primary highway.
**Task:**
Given a highway number, write a program to determine if it is a primary or auxiliary highway. If the highway is auxiliary, the program should also indicate which primary highway it serves and its direction (north/south or east/west).
### Example Scenarios:
**Scenario 1: Input - 90**
```txt
I-90 is primary, going east/west.
```
Explanation: The input number 90 indicates a primary interstate running east/west.
**Scenario 2: Input - 290**
```txt
I-290 is auxiliary, serving I-90, going east/west.
```
Explanation: The input number 290 indicates an auxiliary highway serving the primary interstate I-90, which runs east/west.
**Scenario 3: Input - 0**
```txt
0 is not a valid interstate highway number.
```
Explanation: The input number 0 is not within the valid range of 1 to 999 for interstate highways.
**Scenario 4: Input - 200**
```txt
200 is not a valid interstate highway number.
```
Explanation: The input number 200 is not a valid auxiliary highway because '00' is not a valid primary highway.
### C Programming Code Snippet:
Here is the basic structure of a C program to implement the above logic:
```c
#include <stdio.h>
int main(void) {
int highwayNumber;
scanf("%d", &highwayNumber);
