Q4) The L2 Norm (or Euclidean Norm) is often used to calculate the magnitude of a vector or determine a best fit. Write a program that takes the L2 norm of 3 numbers, using the math.h library. This library grants access to pow(x, y), and sqrt (x). pow(x,y) raises x to the y-th power. To use these functions in your code, simply put #include in the line after #include . You may now use the functions mentioned previously (and so many more) without further reference. The L2 norm of three numbers is shown below: Prompt the user to enter 3 numbers the string "Enter 3 numbers (in the format: a b c):" and print the L2 norm of the 3 numbers. Print the answer with 2 decimal place precision as seen in the example below. Enter 3 numbers (in the format: a b c): 1 2 3 3.74 Because we used an external library, we need to tell the compiler to link that library, or else it won't know where the math functions are coming from. -1 is a compiler flag to link a library, followed by something that represents that library (for math.h the linker flag is-Im). To get your program to compile, you will need to add -1m to the gec command, i.e. run: gcc 12.norm.c1m-o 12.norm Notes: A, B, and C will all be integers, but the output X will be a float. There are NO double spaces. Name your file 12 norm.c Side-note: If your ever confused about a function like sqrt O, keep in mind you can almost always use the man command to get more information about C and C++ functions (e.g. man sqrt), it will even give you the linker flags
