Win32 Project: Develop a Thread based window calculator to perform thefollowing

Question

Win32 Project:

Develop a Thread based window calculator to perform thefollowing mathematical operation:

ü     Sin(x)                5 Marks

ü     Cos(x)               5 Marks

ü     Tan(x)               5 Marks

TIP:

User should specify the inputs and the operations to beperformed in sequence e.g if user presses the following sequence ofbuttons

Sin (1), Cos (3) and Tan (4) then user presses “equalto” button.

In this case first thread will calculate the Sin (1) and willwrite output in the edit box given below. After writing its output,it will indicate the second thread to start its operation, secondthread will calculate Cos (3) and will write its output in the editbox, after its completion it will indicate the third thread tostart its operation. Third thread will calculate Tan (4) and willwrite its output. In this way all three threads will becompleted.
