4) The Heat Index is what the temperature feels like in the context of humidity. For example, if the temperature is 90 degree Fahrenheit and the relative humidity is 70%, then it feels much warmer-closer to 105 degrees F. Here's the formula for computing the Heat Index HI where T is the temperature in degrees Fahrenheit and R is the relative humidity (a percentage in the range 0.100 inclusive). Write a complete C++ program that inputs a temperature T, and outputs the Heat Index for the relative humidity values 10, 20, 30,.., 100. Assume the constants c1 through c9 are predefined in Ct+, so you can simply refer to these by name. Also assume valid input. -CNWI- 90 10% : 20%: _ 85.9091 86.3358 0% : 87.926 40% : 90.6797 50%: 94.5969 60% : 99.6777 70%; 105,922 80% : 113.33 90%: 121.901 100%; 131 , 636 #include #include using namespace std; int main()
