Output each floating$-$point value with two digits after the decimal point, which can be achieved by executing

cout $$ fixed $$ setprecision$(2)$; once before all other cout statements.

$(1)$ Prompt the user to enter five numbers, being five people's weights. Store the numbers in a vector of doubles. Output the vector's numbers on one line, each number followed by one space. $(2$ pts$)$

Ex:

Enter weight $1$:

$236\mathrm{.}0$

Enter weight $2$:

$89\mathrm{.}5$

Enter weight $3$:

$142\mathrm{.}0$

Enter weight $4$:

$166\mathrm{.}3$

Enter weight $5$:

$93\mathrm{.}0$

You entered: $236\mathrm{.}0089\mathrm{.}50142\mathrm{.}00166\mathrm{.}3093\mathrm{.}00$

$(2)$ Also output the total weight, by summing the vector's elements. $(1$ pt$)$

$(3)$ Also output the average of the vector's elements. $(1$ pt$)$

$(4)$ Also output the max vector element. $(2$ pts$)$

Ex:

Enter weight $1$:

$236\mathrm{.}0$

Enter weight $2$:

$89\mathrm{.}5$

Enter weight $3$:

$142\mathrm{.}0$

Enter weight $4$:

$166\mathrm{.}3$

Enter weight $5$:

$93\mathrm{.}0$

You entered: $236\mathrm{.}0089\mathrm{.}50142\mathrm{.}00166\mathrm{.}3093\mathrm{.}00$

Total weight: $726\mathrm{.}80$

Average weight: $145\mathrm{.}36$

Max weight: $236\mathrm{.}0089\mathrm{.}5$

Enter weight $3$:

$142\mathrm{.}0$

Enter weight $4$:

$166\mathrm{.}3$

Enter weight $5$:

$93\mathrm{.}0$

You entered: $236\mathrm{.}00,89\mathrm{.}50,142\mathrm{.}00,166\mathrm{.}30,93\mathrm{.}00$

$(2)$ Also output the total weight, by summing the vector's elements. $(1$ pt$)$

$(3)$ Also output the average of the vector's elements. $(1$ pt$)$

$(4)$ Also output the max vector element. $(2$ pts$)$

Ex:

Enter weight $1$:

$236\mathrm{.}0$

Enter weight $2$:

$89\mathrm{.}5$

Enter weight $3$:

$142\mathrm{.}0$

Enter weight $4$ :

$166\mathrm{.}3$

Enter weight $5$:

$93\mathrm{.}0$

You entered: $236\mathrm{.}00,89\mathrm{.}50,142\mathrm{.}00,166\mathrm{.}30,93\mathrm{.}00$

Total weight: $726\mathrm{.}80$

Average weight: $145\mathrm{.}36$

Max weight: $236\mathrm{.}00$
