/*
Analyze the questions and write proper definition and example code for the following:
(5 X 2 = 10)
1. What are control structures?
2. What are conditional constructs?
3. What are looping constructs?
4. Write a program to get input for 4 numbers and find the smallest among all using if expression.
5. Write a program to input a character and print whether it is vowel or consonant using when expression.
(1 X 10 = 10)
6. Write the different variations of for loop using suitable example programs.
