1) Write and run a C code explained below; Program asks the user to insert the integer 0 to calculate the volume of a sphere and to insert any integer else to calculate the volume of a cube. The program should also ask the user to insert the length of the radius if 0 inserted or ask the user length one of the edges of the cube. Finally, program returns the volume of the sphere (if 0 inserted) or the volume of the cube (if else inserted). Moreover; If the user inserts 0 ; program asks whether to take pi=3 or pi=3.14 for the sphere volume calculation. (Likewise, program will ask the user to insert 0 to take 3 as pi and else number to take 3.14 [by using nested if statements]) 2) Draw the flowchart algorithm of the problem..
