Sure! Here's a cheat sheet for Pascal programmers:
Data Types: - integer: represents whole numbers - real: represents floating-point numbers - boolean: represents true or false values - char: represents single characters - string: represents a sequence of characters
Variables:
- Declare a variable: var variableName: dataType;
- Assign a value to a variable: variableName := value;
- Read input from user: ReadLn(variableName);
- Display output: WriteLn(variableName);
Operators:
- Arithmetic operators: +, -, *, /, div, mod
- Comparison operators: =, <>, <, >, <=, >=
- Logical operators: and, or, not
Conditional Statements:
- If statement:
if condition then
statement
else
statement
Loops:
- For loop:
for variable := startValue to endValue do
statement
- While loop:
while condition do statement
Arrays:
- Declare an array: var arrayName: array[indexType] of dataType;
- Access array elements: arrayName[index]
Procedures and Functions:
- Declare a procedure:
procedure procedureName(parameters);
begin
// code
end;
- Declare a function:
function functionName(parameters): returnType; begin // code end;
File Handling:
- Assign a file: Assign(fileVariable, fileName);
- Open a file: Reset(fileVariable);
- Close a file: Close(fileVariable);
- Read from a file: Read(fileVariable, variableName);
- Write to a file: Write(fileVariable, variableName);
This cheat sheet should provide you with a quick reference for common Pascal syntax and constructs. Remember to consult the official Pascal documentation for more detailed information and examples.
