Problem: Write a program that takes as input two complex numbers and performs one of the following operations on them: addition, subtraction, multiplication, or division. The output should be the result of the operation, with 3 digits after the decimal point. The input should be two pairs of floating-point numbers indicating the real and imaginary parts of the complex numbers, separated by spaces, followed by a letter indicating the operation to be performed. The output should be two space-separated numbers, with the real part followed by the imaginary part.

Problem: Write a program that takes as input two complex numbers and performs one of the following operations on them: addition, subtraction, multiplication, or division. The output should be the result of the operation, with 3 digits after the decimal point. The input should be two pairs of floating-point numbers indicating the real and imaginary parts of the complex numbers, separated by spaces, followed by a letter indicating the operation to be performed. The output should be two space-separated numbers, with the real part followed by the imaginary part.

Student submission:
#include<simplecpp>
main_program{
	float a,b,c,d;
	char e,A,S,M,D;
	cin >>a>>b>>c>>d>>e;
	{if(e==A); 
Then; cout << a+c<<" "<<b+d<<endl;
	else
		(e==S);
Then; cout << c-a<<" "<<d-b<<endl;
	else
		(e==M);
		Then; cout <<(a*c-b*d)<<" "<<(a*d+b*c)<<endl;
	else
		(e==D);
		Then; cout <<(a*c+b*d)/(c*c+d*d)<<" "<<endl;
	}
