Compile in Pascal language, what does the pascal compilation system belong to

The Pascal compilation system is a system software. Pascal is the first structured programming language with rigorous syntax, clear hierarchy, easy to write and readable programs. Pascal language is widely used in various software, and the program is divided into name (self-proposed after program), setting (defined after var), start (begin), program (body), read (read read ln), and end (end), with strong structural hierarchy, rigorous and tight.

System software refers to the system that controls and coordinates the computer and external equipment, supports the development and operation of application software, and is a collection of various programs without user intervention, and its main function is to schedule, monitor and maintain the computer system; Responsible for managing the various independent hardware drafts in the computer system so that they can work in harmony. System software enables computer users and other software to treat the computer as a single entity, regardless of how each piece of underlying hardware works.

The Pascal compilation system is a programming language. It was designed and founded in the late sixties by Professor Niklaus Wirth of Switzerland. Pascal is the first structured programming language with rigorous syntax, clear hierarchy, easy to write and readable programs.

Pascal language is widely used in various software, and the program is divided into name (self-proposed after program), setting (defined after var), beginning (begin), program (body), reading silver calendar (read ln), end (end), with strong structural hierarchy, rigorous and close.

It has rich data types and concise and flexible operation statements. Pascal is an important milestone in the development of high-level languages. The Pascal language was the first language to systematically embody and define the concept of structured programming.

1 Simple judgment.

varscore:longint;

beginreadln(score);If score>85 then writeln('very good');Judge whether it is higher than 85 points.

elsebegin

if score<60 then writeln('bad'Judge whether it is hell for 60 points.

else writeln('good');

end;end.

2 From the question, it can be seen that the number of rabbits with childbearing potential in the current month is equal to the total number of rabbits in the previous month, then the total number of rabbits in the current month is the number of rabbits in the previous month (original) + the number of rabbits in the previous month (newborn).

vara,b,c,i:longint;

begina:=1;last month.

b:=2;Last month.

for i:=3 to 12 do

beginc:=a+b;Find the number of rabbits for the month.

a:=b;Last month became last month.

b:=c;This month has become a mountain month.

end;January and February are known, and the current month is December after ten cycles(c); Output the number of rabbits for the month

The first is simple judgment;

The second is the Fibonacci sequence;

Very good to do
