# Simula Cheatsheet Simula is a programming language that is particularly well-suited for simulations and modeling. Here is an overview of some of its unique features and basic syntax. ## Variables ### Declaration
integer i;
real x;
boolean flag;
### Assignment
i := 42;
x := 3.14;
flag := true;
## Functions ### Declaration
procedure helloWorld();
begin
write("Hello, world!");
end;
### Call
helloWorld();
## Loops ### For loop
for i := 1 to 10 do
begin
write(i);
end;
### While loop
while flag do
begin
write("Looping...");
end;
## Conditionals ### If statement
if x > 0 then
begin
write("Positive");
end;
### If-else statement
if x > 0 then
begin
write("Positive");
end
else
begin
write("Non-positive");
end;
## File manipulation ### Reading from a file
textFile file;
file.open("filename.txt", "in");
while not file.eof do
begin
file.readln(line);
write(line);
end;
file.close();
### Writing to a file
textFile file;
file.open("filename.txt", "out");
file.writeln("Hello, world!");
file.close();
