C++ <complex> - operator- Function
The C++ <complex> operator- function is used to apply minus operator to two complex numbers or a complex and a scalar.
Syntax
template<class T>
complex<T> operator-
(const complex<T>& lhs, const complex<T>& rhs);
template<class T>
complex<T> operator-
(const complex<T>& lhs, const T& val);
template<class T>
complex<T> operator-
(const T& val, const complex<T>& rhs);
Parameters
lhs |
Specify left-hand side complex number of matching type. |
rhs |
Specify right-hand side complex number of matching type. |
val |
Specify scalar value of matching type. |
Return Value
Returns a new complex number as a result of performing operation.
Example:
The example below shows the usage of operator- function.
#include <iostream>
#include <complex>
using namespace std;
int main (){
complex<double> z1 (10, 20);
complex<double> z2 (2, 3);
complex<double> z3, z4;
//result of z1 - 3.0 is stored in z3
z3 = z1 - 3.0;
cout<<"z3 : "<<z3<<"\n";
//result of z1 - z2 is stored in z4
z4 = z1 - z2;
cout<<"z4 : "<<z4<<"\n";
return 0;
}
The output of the above code will be:
z3 : (7,20) z4 : (8,17)
