复数演示实验，实现下列六种基本运算：1）由输入的实部和虚部生成一个复数；2）两个复数求和；3）两个复数求差；4）两个复数的求积；5）从已知复数中分离出实部；6）从已知复数中分离出虚部。运算结果以相应的复数或实数的表示形式显示。-Complex demonstration experiment, to achieve the following six basic operations: 1) from the input of the real and imaginary parts generate a plural　2) 2 complex summation　3) 2 complex seeking poor　4) 2 plural quadrature　5) complex isolated from the known real part　6) isolated from the known complex imaginary part. Computing the results of the corresponding complex or real numbers that are displayed.
