Hello everyone. I wrote a Pascal program to calculate the volume of triangles (I was bored ...) but it appears to be buggy.
If someone could point me to where it went wrong that would be great, thanks.
Code:
program tv;
var
triangle, triangleside, trianglebottom, volume, height, af: integer;
ex, un: string;
begin
Writeln('Hello. This program will calculate Triangular Volumes.');
Writeln('');
Writeln('');
Writeln('Please input the unit of measurement: ');
Readln(un);
Writeln('');
Writeln('Please input the size of your triangle''s side in ', un,': ');
Readln(triangleside);
Writeln('');
Writeln('Please input the size of your triangle''s bottom in ', un,': ');
Readln(trianglebottom);
af := triangleside + trianglebottom;
triangle := af DIV 2;
Writeln('');
Writeln('The area of your triangle is: ', triangle, '', un, ' squared.');
Writeln('Please input the height of your object: ');
Readln(height);
Writeln('');
volume := af * height;
Writeln('The volume of your triangle is: ', volume, '', un, 'to the power of 3.');
Writeln('So long, and thanks for all the numbers.');
Writeln('Press ENTER to exit.');
Readln(ex);
end.
For starters, your basic formula for calculating the area is wrong.
Code:
af := triangleside + trianglebottom;
triangle := af DIV 2;
The formula for the area of a triangle is: 1/2 (base * height).
You need to multiply triangle height by triangle bottom. Triangle side would only work in a right angle triangle.
