complex()               Create a Complex Number

 #include   <complex.h>

 complex complex(real, imag);
 double real;           The real part
 double imag;           The imaginary part

        The complex() function creates a complex number out of the two
        numbers you pass it.

       Returns:     The complex number.

   -------------------------------- Example ---------------------------------

 #include <iostream.h>
 #include <complex.h>

 int main(void)

    double x = 9.2, y = 5.1;
    complex z = complex(x, y);
    cout << "The complex number z = "<< z << "\n";
    return 0;
