Q$1.$ Write a $C$ language program which will take three real numbers from the keyboard into three different variables. The program should find the minimum of these three numbers using nested if else statements.

Q$2.$ Write a program that will enter two float numbers $x$ and $Y($from Keyboard$)$ as input and will find and print the value of $f(x_2))$ as an output $($Hint: Use math.h for powers$).$ The function $f(x_a)$ is define as follows:

Q$3.$ Write a $C$ language program which will take a real number and a character from the keyboard. The input should be given, for example, like $2\mathrm{.}3k$ or $5\mathrm{.}4m$ where $k$ represents kilometer and $m$ represents mile. If the user enters a mile value the program should convert and display the kilometer equivalent. If the user enters a kilometer value the program should calculate and display the mile equivalent. USE IF STATEMENTS. $(1$ kilometer $=0\mathrm{.}6214$ mile
