复数是表示为a + bi的数字,其中i是虚数,而a和b是实数。一些关于复数的例子是-
2+5i 3-9i 8+2i
通过将结构传递给函数来添加复数的程序如下所示-
#include <iostream>
using namespace std;
typedef struct complexNumber {
float real;
float imag;
};
complexNumber addCN(complexNumber num1,complexNumber num2) {
complexNumber temp;
temp.real = num1.real + num2.real;
temp.imag = num1.imag + num2.imag;
return(temp);
}
int main() {
complexNumber num1, num2, sum;
cout << "Enter real part of Complex Number 1: " << endl;
cin >> num1.real;
cout << "Enter imaginary part of Complex Number 1: " << endl;
cin >> num1.imag;
cout << "Enter real part of Complex Number 2: " << endl;
cin >> num2.real;
cout << "Enter imaginary part of Complex Number 2: " << endl;
cin >> num2.imag;
sum = addCN(num1, num2);
if(sum.imag >= 0)
cout << "Sum of the two complex numbers is "<< sum.real <<" + "<< sum.imag <<"i";
else
cout << "Sum of the two complex numbers is "<< sum.real <<" + ("<< sum.imag <<")i";
return 0;
}输出结果
上面程序的输出如下-
Enter real part of Complex Number 1: 5 Enter imaginary part of Complex Number 1: -9 Enter real part of Complex Number 2: 3 Enter imaginary part of Complex Number 2: 6 Sum of the two complex numbers is 8 + (-3)i
在上述程序中,结构complexNumber包含复数的实部和虚部。这在下面给出-
struct complexNumber {
float real;
float imag;
};该函数addCN()接受两个类型为complexNumber类型的参数,并将两个数字的实部和虚部相加。然后,将增加的值返回到main()函数。这在下面给出-
complexNumber addCN(complexNumber num1,complexNumber num2) {
complexNumber temp;
temp.real = num1.real + num2.real;
temp.imag = num1.imag + num2.imag;
return(temp);
}在该main()方法中,数字的值是从用户那里获得的。这在下面给出-
cout << "Enter real part of Complex Number 1: " << endl; cin >> num1.real; cout << "Enter imaginary part of Complex Number 1: " << endl; cin >> num1.imag; cout << "Enter real part of Complex Number 2: " << endl; cin >> num2.real; cout << "Enter imaginary part of Complex Number 2: " << endl; cin >> num2.imag;
这两个数字的和是通过调用addCN()函数获得的。然后打印总和。这在下面给出-
sum = addCN(num1, num2);
if(sum.imag >= 0)
cout << "Sum of the two complex numbers is "<< sum.real <<" + "<< sum.imag <<"i";
else
cout << "Sum of the two complex numbers is "<< sum.real <<" + ("<< sum.imag <<")i";
