Exercise $1)$ create a for loop that decrement from $21$ to $-21,$ inclusive, with a decrement step of $5$ at each loop iteration. Also count the number of times that the loop counter is multiple of $2.$ The program prompts:

o the numbers in the for loop.

o the total numbers in the for loop that are multiple of $2$ as:

There are $\_\_\_$numbers that are multiple of $2$ in the for loop counter.

Exercise $2)$ create a program that will ask the user to input the start $($initial value of the counter$).$ After it$,$ create a for loop that starts with the number entered by the user and counts to $30$ with an increment step of $4$ at each loop iteration. The initial value of the counter must be between $1$ and $10.$
