1. Assembly language --- Area of a Polygon program
Write a program to find the area of any polygon given its vertexes.
Inputs:Â Â The input is the set of polygons.
Outputs:Â Â Label and print the area value for each input.
Restrictions:Â Â You are to use one-dimensional array(s) to hold vertex values.
You are to use Functions/Procedures in your implementation.
Place your input and output into a file.
Consider:  Area = ½ ? ( Xi+1 Yi - Xi Yi+1 )
Repeat the first point in the polygon in setting up the list of points for the above loop. Loop
through the points in a clockwise process form point to point.
Solution
fid = fopen('input.txt');
tline = fgetl(fid);
num=1;
while ischar(tline)
disp(tline)
[x,rem]=strtok(tline,':')
[y,rem]=strtok(rem,':')
a=str2num(x);
b=str2num(y);
area = 1/2*sum(a.*b([2:end,1])-b.*a([2:end,1]));
fprintf('Area of polygon is: %.2f ', area);
fileID = fopen('output.txt','a');
fprintf(fileID,'%d :',num);
fprintf(fileID,'%f ',area);
fclose(fileID);
tline = fgetl(fid);

2. num++;
end
fclose(fid);
Note : input file should be like
[0 1 2]:[1 2 3]
where x=[0 1 2] y=[1 2 3]
