The constructor initializes the data member amount to 0.A function named addGas that accepts a parameter of type double . The value of the amount instance variable is increased by the value of the parameter.A function named useGas that accepts a parameter of type double . The value of the amount data member is decreased by the value of the parameter. However, if the value of amount is decreased below 0 , amount is set to 0 .A function named isEmpty that accepts no parameters and returns a boolean value. isEmpty returns a boolean value: true if the value of amount is less than 0.1 , and false otherwise.A function named getGasLevel that accepts no parameters. getGasLevel returns the value of the amount data member.class GasTank{private:double amount;public:GasTank();void addGas(double);void useGas(double);bool isEmpty();double getGasLevel();};GasTank::GasTank(){amount = 0;}void GasTank::addGas(double a){amount += a;}void GasTank::useGas(double a){amount -= a; if (amount < 0) amount = 0; }bool GasTank::isEmpty(){if(amount < .1) return true; else return false;}double GasTank::getGasLevel() {return amount;} Why is Visual literacy important A student has started a lawn care business.
