Some more keywords....

I run a program for complex numbers in C .There are various type of complex number keyword declared in
#include <complex> .Here are some:-

1)_complex                                    //takes double
2)_C_double_complex                   //takes double

3)_C_float_complex                       //takes float

4)_C_ldouble_complex                  //takes long double

I have used them in my program and perform various operation like addition ,substraction,multiplication and division.Here is the program and output:-

#include<iostream>

#include<stdio.h>

#include<conio.h>

#include<msclr/safebool.h>

#include<complex>

void main()

{

bool a=false; //C++

//printf("boola=",a);

_complex c={12.66,34.787};

_complex d={1,34};

_complex e={(c.x+d.x),(c.y+d.y)};

printf("%lf\t%lf\n",e.x , e.y);

_C_double_complex a={12.34,65.7};

_C_double_complex b={2.34,65.7};

_C_double_complex g={a._Val[0]-b._Val[0],a._Val[1]-b._Val[1]};

printf("%lf\t%lf\n",g._Val[0] , g._Val[1]);

    

_C_ldouble_complex f={234.79345,12.64233};

_C_ldouble_complex h={1,2};

_C_ldouble_complex i={f._Val[0]*h._Val[0],f._Val[1]*h._Val[1]};

printf("%Lf\t%Lf\n",i._Val[0] , i._Val[1]);

_C_float_complex j={11.89,2.001};

_C_float_complex k={1,2.001};

_C_float_complex l={j._Val[0]/k._Val[0],j._Val[1]/k._Val[1]};

printf("%f\t%f\n",l._Val[0] , l._Val[1]);

_getch();

}

Output:-

13.660000       68.787000

10.000000       0.000000

234.793450      25.284660

11.890000       1.000000

*Here we use an another variable bool which takes two values true and false.It is declared in     header #include<msclr/safebool.h> .
