Programming Assignments with Using MarieSim

PA1: Write a MARIE assembly language program to compute D = (A+B) - (C-B) + (A-C). Please download and use the skeleton code (expr_skeleton.mas).

PA2: Write a MARIE assembly language program to add all positive values in an array and display the sum. Please download and use the skeleton code (array_skeleton.mas).

PA3: Write a MARIE program to compute factorial using a loop. As the MARIE architecture does not have multiplication instruction, a subroutine Mult that multiplies two non-negative integers is given in a skeleton code which can be downloaded here (fac_loop_subr_skeleton.mas).

Note that factorial of N can be defined as below.

The following C++ program computes factorial using a loop for your reference.

int main(){

int N, C;

cout << "Please enter an integer:" << endl;

cin >> N;

if (N == 0)

return 1;

else {

C = 1;

for (int i = 1; i <= N; i++)

C = C*i;

}

cout << C << endl; // Print result

return 0;

}

Please submit your MARIE source codes in Canvas by the due day.
