Question: 1

Convert the following C++ program into an x86 assembly language program.
Comment the start of each "code block" that performs one of the listed mathematical calculations.
Comments go to the right of the actual code, all starting on the same column.
 and also need ASM file.

// Global variables
int a = 5;
int b = 6;
int c = 7;
int d = 8;
int e = 2;
int f = 3;
int g = 1;
int h = 4;

// Code
int main()
{
    --g;
    b = f + h;
    e = d + 22 - c - a;
    f = -g;
    ++a;
    g = f + e - 5;
    a = d + 19 - b;
    h = c + a + (-f);

    // Move a into the eax register
    // Move b into the ebx register
    // Move c into the ecx register
    // Move d into the edx register
    // Call the DumpRegs function   

    // Move e into the eax register
    // Move f into the ebx register
    // Move g into the ecx register
    // Move h into the edx register
    // Call the DumpRegs function   
   
    g = g + 6;
    f = 16;
    --h;
    d = 5 - e;
    b = -b;
    e = -g + 11 - a;
    f = d + c - a;
    c = c - 100 + b;
   
    // Move a into the eax register
    // Move b into the ebx register
    // Move c into the ecx register
    // Move d into the edx register
    // Call the DumpRegs function   

    // Move e into the eax register
    // Move f into the ebx register
    // Move g into the ecx register
    // Move h into the edx register
    // Call the DumpRegs function   
   
    // Call the WaitMsg function
}

 

Question 2  

Convert the following C++ program into an x86 assembly language program.
Comment the start of each "code block" that performs one of the listed mathematical calculations.
Comments go to the right of the actual code, all starting on the same column.
and also need ASM file.

 

// Global variables
char  a = 5;
short b = 7;
int   c = 11;
int   d = 13;

// Code
int main()
{
    b = -a;
    d = a - 9;
    c = static_cast(a);
    d = static_cast(b);
    a = a - 3;
    d = c;
   
    // Move a into the eax register
    // Move b into the ebx register
    // Move c into the ecx register
    // Move d into the edx register
    // Call the DumpRegs function   

    a = 9;
    b = 18;
    c = 7;
    d = 5;
    c = -a + b + c + d - (d + c + b + a);
    d = b - c - d - a + b + c - d - a - c - a + b + a + d + c - b;

    // Move a into the eax register
    // Move b into the ebx register
    // Move c into the ecx register
    // Move d into the edx register
    // Call the DumpRegs function   

    // Call the WaitMsg function
}
