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.

  • Errors and warning will be printed to the terminal.

  • Symbol table will be generated in a txt file named symbol_table.txt.

  • The quadruples will be generated in a txt file named quads.txt.

Quadraples Description

Quadraple Description
PUSH (value) Pushing (value) to stack
POP (ID) Pop value from stack to the (ID)
NOT 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
LE Check if the first operand is less than or equal the second and store the comparison result in temp reg
GE Check if the first operand is greater than or equal the second and store the comparison result in temp reg
JMP L(): Unconditional Jump to label
JUMPZERO L(): Jump if the zero flag from previous command is zero
JMPNONZERO L(): Jump if the zero flag from previous command is non-zero
Convi (var/value) Convert float to integer
Convf (var/value) Convert integer to float
