Question

ASSEMBLY LANGUAGE FOR X86 (MASM) Please use modify the code below, it is just a loop of 10 years......DON NOT USE A JAVA DISASSEMBLER OF BUTCHERS ALGORITHIM.

Use Butcher's algorithm to calculate Easter for the next ten years in x86 assembly language. Use the code below to start

TITLE MASM Template                        (main.asm)

Explanation / Answer

ANSWER::

double ParseAtom(char*& expr)
{
char* end_ptr;
double res = strtod(expr, &end_ptr);
expr = end_ptr;
return res;
}
double ParseFactors(char*& expr) {
double num1 = ParseAtom(expr);
for(;;)
{
char op = *expr;
if(op != '/' && op != '*')
return num1;
expr++;
double num2 = ParseAtom(expr);
if(op == '/')
num1 /= num2;
else
num1 *= num2;
}
}
double ParseSummands(char*& expr)
{
double num1 = ParseFactors(expr);
for(;;) {
char op = *expr;
if(op != '-' && op != '+')
return num1;
expr++;
double num2 = ParseFactors(expr);
if(op == '-')
num1 -= num2;
else
num1 += num2;
}
}

double EvaluateTheExpression(char* expr)
{
return ParseSummands(expr);
};
