Hello, write code in c++. primary u. s. interstate highways are numbered 1-99. odd numbers (like the 5 or 95) go north/south, and evens (like the 10 90) go east/west. auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two-digits. thus, the 405 services the 5, and the 290 services the 90. 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. if the input is 90, the output is: the 90 is primary, going east/west. if the input is 290, the output is: the 290 is auxiliary, serving the 90, going east/west. if the input is not 1-999 such as 0, the output is: 0 is not a valid interstate highway number.

Please Find attached  c++ code file.

Explanation:

Check if highway is primary or auxiliary.

Use if condition to check if the entered number is in between 0 and 99.If it's true than the highway is primary otherwise it's an auxiliary highway.

Check if highway number is even / odd.

To check if a number is even or odd we use simple modulo formula. In mathematics modulo returns the reminder of a division operation on two numbers.If modulo of a number and 2 is equal to zero than that number is an even number other wise its an odd number.

Find Primary high number for an auxiliary highway

As mentioned in the question last two digits of highway number is the number of primary high.

To Find last two digits of number apply modulo operation on highway number and 100. it will provide last two digits of number specifying our primary highway.
