Laboratory #$5$

Objectives: To use library functions to evaluate equations. To

understand nested loop structures,

both 'for' and 'while'.

Problem$1$:

Add a line that prompts the user to enter the diameter of a sphere.

Read in and store the number into a variable called diameter $($you

will need to declare any variables that you use$).$

The diameter is twice as long as the radius, so calculate and store the

radius in an appropriately named variable.

The formula for the volume of a sphere is: $V=\frac{4}{3}*$

Convert the formula to $C++$ code and add a line which calculates and

stores the value of volume in an appropriately named variable. Use

pow $(x,y)$ to cube the radius.

Print your results to the screen with an appropriate message.

Problem $2$:

Using for loops control structure write a program segment to print the

following pattern:

$++++,+$

$++++,++$

$++++,+++$

$++++,++++$

Problem $3$:

Repeat problem $2$ using while loop control structures.
