Problem: The problem statement is to find the root of the equation f(x) = x3 - 6x2 + 11x - 6 between x1 and x2 using the bisection method. The input is two high-precision floating-point values of type double representing x1 and x2 respectively. The output is the root of the equation correct up to 3 decimal places. The constraints are that -100 <= x1, x2 <= 100, and x1 < x2. The program should not print any general messages, but only the root of the equation correct up to 3 decimal places.

Problem: The problem statement is to find the root of the equation f(x) = x3 - 6x2 + 11x - 6 between x1 and x2 using the bisection method. The input is two high-precision floating-point values of type double representing x1 and x2 respectively. The output is the root of the equation correct up to 3 decimal places. The constraints are that -100 <= x1, x2 <= 100, and x1 < x2. The program should not print any general messages, but only the root of the equation correct up to 3 decimal places.

Student submission:
#include<simplecpp>
main_program{
	float x1,x2;
	cin>>x1>>x2;
	bool x1pos=((x1-1)*(x1-2)*(x1-3)>0);
	while(x2-x1>0.000001){
		float xm=(x1+x2)/2;
		bool xmpos=((xm-1)*(xm-2)*(xm-3)>0);
		if(x1pos==xmpos){
			x1=xm;
		}
		else{x2=xm;}
	}
	cout << fixed; // uses fixed floating point representation
	cout.precision(3); // print three digits after the decimal point
	cout<<double(x1);
}

Grading criterion: Is the loop used for iterations correctly breaking after a threshold
Rating A: The loop breaks after a certain threshold where no further iterations are required for the root calculation
Rating B: Wrong loop is used which continues infinitely or no loop is used
