==================================== Exercise 1.4 - Temperature Convertor ==================================== Question -------- Write a program to print the corresponding Celsius to Fahrenheit table. Solution -------- .. literalinclude:: ../../languages/cprogs/Ex_1.4_cel2fahr.c :language: c :tab-width: 4 .. runcode:: ../../languages/cprogs/Ex_1.4_cel2fahr.c :language: c :codesite: ideone Explanation =========== In the previous exercise we converted Fahrenheit temperature to Celsius temperature. In this program we are going to convert a given Celsius temperature to Fahrenheit temperature using the formula C=(5/9)(F-32) To do this we declare some variables in the beginning of the program so that they can be used in the later stages of the program. The variables in this program are: lower,upper,step, celsius,fahr. The variable lower is assigned the value 0 similarly upper to 300, step to 20, and Celsius to lower. So when the program enters the while loop it checks whether celsius <= upper is true if it is true then it assigns the variable fahr (9.0/5.0) * celsius + 32.0 and then it prints out put. .. seealso:: * :c-suggest-improve:`Ex_1.4_cel2fahr.c` * :c-better-explain:`Ex_1.4_cel2fahr.rst`
