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 real1,imag1,real2,imag2;
	char ch;
	cin>>real1>>imag1>>real2>>imag2;
	cin>>ch;
	if(ch=='A'){
		cout<<fixed;
		cout.precision(3);
		cout<<real1+real2<<" "<<imag1+imag2;
	}
	else if(ch=='S'){
		cout<<fixed;
		cout.precision(3);
		cout<<real1-real2<<" "<<imag1-imag2;
	}
	else if(ch=='M'){
		cout<<fixed;
		cout.precision(3);
		cout<<((real1*real2)-(imag1*imag2))<<" "<<imag1*real2+imag2*real1;
	}
	else if(ch=='D'){
		cout<<fixed;
		cout.precision(3);
		cout<<((real1*real2)+(imag1*imag2))/(real2*real2+imag2*imag2)<<" " <<((imag1*real2)-(real1*imag2))/(real2*real2+imag2*imag2);
	}
