how to program the calculator calculations using TURBO PASCAL 7.0

Assalamu'alaikum Wr.Wb.
regards the pascal mania, on a clear night, I am going to share a tutorial to make the program count or what we often refer to as the machine count CALCULATOR. in essence, we will create a program that is possessed four elements of the calculation, the first multiplication, division, addition, and the last reduction. just follow the steps below carefully.

How to make the program count CALCULATOR :

1. Turbo pascal you open the program.
2. Select the file - new.
3. And write the code as below.
summation program;
uses crt;
var a,b,result : real;
begin
clrscr;
write('enter the value 1 :');readln(a);
write('enter the value 2 :');readln(b);
writeln;
result:=a+b;
writeln(results from the sum: ',result;
readln;
end.


reduction program;
uses crt;
var a,b,result : real;
begin
clrscr;
write('enter the value 1 :');readln(a);
write('enter the value 2 :');readln(b);
writeln;
result:=a-b;
writeln(result of the reduction : ',result);
readln;
end.


multiplication program;
uses crt;
var a,b,result : real;
begin
clrscr;
write('enter the value 1 :');readln(a);
write('enter the value 2 :');readln(b);
writeln;
result:=a*b;
writeln(the result of multiplication : ',result);
readln;
end.


division program;
uses crt;
var a,b,result : real;
begin
clrscr;
write('enter the value 1 :');readln(a);
write('enter the value 2 :');readln(b);
writeln;
result:=a/b;
writeln(the result of the division : ',result);
readln;
end.
4. Then compile - compile or alt + f9 to make sure there are no errors in your program code.
5. If there are no errors please select run - run.
6. Congratulations you can make the program count yourself.
