Q$2.$ In statistical analysis, one is frequently interested in the "spread" of data. One such measure is the standard deviation. The standard deviation of $5$ numbers $x0,x1,x2,x3,x4$ is given by the following formula

$\sqrt[\phantom{2}]{\frac{(x0-\text{a}\text{v}\text{g}{)}^2+(x1-\text{a}\text{v}\text{g}{)}^2+(x2-\text{a}\text{v}\text{g}{)}^2+(x3-\text{a}\text{v}\text{g}{)}^2+(x4-\text{a}\text{v}\text{g}{)}^2}{5}}$

here avg is the average of $x0,x1,x2,x3,$ and $x4,$ i$.$e$.$ avg has the value

$\frac{x0+x1+x2+x3+x4}{5}$

Note that this expression occurs $5$ times in the formula for the standard deviation. In your program, the computation of avg should occur only once. Write a program that prompts the user for integer values for variables $x0,x1,x2,x3,$ and $x4,$ and prints the standard deviation of these numbers in fixed point format with $5$ decimal places.
