3. Use arrays to read the following input file: 30.0 45.0 60.0 90.0 4 Then process the data and generate the following file: NX (degree) cos(X) 30.0 45.0 60.0 90.0 0.8667 0.7071 0.5 0.0 4 [Hint: Read the array element in the main function, pass the array to a user defined function named array process and compute cos(X) and print the above table inside the function. The function may have a return type void]
