C Program - Write main and two other functions named ComputeMaximum and ComputeMinimum that return the larger and smaller, respectively, of two type double arguments:
1. Each function must be in a separate file.
2. The files containing ComputeMaximum and ComputeMinimum may not contain #defines, #includes, if statements, switch statements, looping statements, or variables that are not formal parameters.
3. All printing must be done in main.
4. The file containing main may only #include standard library header files, and only if needed.
E. Test each Compute… function with the following value pairs: 1 20 20 1 -4 3 3 -4
