Code Writing 1) The Heat Index is what the temperature feels like in the context of humidity. For example, if the temperature is 90 F and the relative humidity is 70%, then it feels much warmer closer to 105 F. Here's the formula for computing the Heat Index HI where T is the temperature in F and R is the relative humidity (a percentag 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 C, so you can simply refer to these by name. Also assume valid input.
