The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journal article $($source$)$:Write a program using inputs age $($years$),$ weight $($pounds$),$ heart rate $($beats per minute$),$ and time $($minutes$),$ respectively. Output the average calories burned for a person.Output each floating$-$point value with two digits after the decimal point, which can be achieved by executingcout $<<$ fixed $<<$ setprecision$(2)$; once before all other cout statements.Ex: If the input is:$4915514860$the output is:Calories: $736\mathrm{.}21$ calories$536136\mathrm{.}3581366.$qx$3$zqy$7$LAB ACTIVITY$2\mathrm{.}4\mathrm{.}1$: LAB: Expression for calories burned during workout$0/10$main.cppLoad default template...Develop modeSubmit modeRun your program as often as you'd like, before submitting for grading.
