Language Descriptions

Tokens

1- Variable and constant Declaration

int x;
int x = 5;
const int x = 5;
string x = "Hello";
string x = "c";

• Available types
  • int
  • float
  • string
  • bool

2- Mathematical and Logical expressions

• Mathematical operator
  • +, -, *, /, %,
• Logical operator
  • ==, !=, >, <, >=, <=
  • and , or , not , xor

3 - Assignment statement

x = 5;
x = "Hello";
x = 5.5;
x = true;

4 - If else statement

if (x == 5 and y == 10) {
  x = 10;
} endif

if (x >= 5 or y <= 10) {
  x = x +1 ;
} else {
  x = x - 1;
}

if (x < 5 and y > 10) {
  x = x + 1;
} else if (x > 5) {
  x = x - 1;
} else {
  x = 0;
} 

5 - While loop

while (x < 5) {
  x = x + 1;
}

6 - Repeat until

repeat {
  x = x + 1;
} until (x == 5);

7 - For loop

for (int i = 0; i < 5; i = i + 1) {
  x = x + 1;
}

8 - Switch case

switch (x) {
  case 1:
    x = 1;
    break;
  case 2:
    x = 2;
    break;
  default:
    x = 0;
}

9 - Function declaration

int func1(int x, int y) {
  return x + y;
}

void func2(int x) {
  x = x + 1;
}

int func3() {
  return 5;
}

10 - Function call

int x = func1(5, 10);
func2(5);
int y = func3();

11 - Block structure

{
  int x = 5;
  {
    x = x + 1;
  }
}

12- Comments

// This is a comment

13- Print

print("Hello World");
print(x);
print(5);
print(5+6);

14- Enum

enum Color {
  RED,
  GREEN,
  BLUE
}
enum Color c = RED;

How to run

• There is a script named build.sh that generates the parser and lexer and takes test file from you as input argurmnt.

• You can run the script by typing the following command in the terminal:

  ./build.sh if_test.c
  

• Note: the test file should be in the test_cases folder.

• It will print the tokens with its line number.

Quadraples Description

Quadraple	Description
PUSH (value)	Pushing (value) to stack
POP (ID)	Pop value from stack to the (ID)
NOT (value)	Getting complement of (value)
ADD (arg1) (arg2) (result)	Adding (arg1) (arg2) and save value to (result)
SUB (arg1) (arg2) (result)	Substracting (arg1) (arg2) and save value to (result)
MUL	Multiply (arg1) (arg2) and save value to (result)
DIV	Divide (arg1) (arg2) and save value to (result)
MOD	Calculate the modules of (arg1) (arg2) and save value to (result)
AND	Perform logical and between (arg1) (arg2) and save value to (result)
OR	Perform logical or between (arg1) (arg2) and save value to (result)
XOR	Perform logical xor between (arg1) (arg2) and save value to (result)
EQ	Check the equality of the two operands and store the comparsion result in temp reg
NE	Check the inequality of the two operands and store the comparsion result in temp reg
LT	Check if the first operand is less than the second and store the comparison result in temp reg
GT	Check if the first operand is greater than the second and store the comparison result in temp reg
