-### Increment and Decrement Operators
-
-RC supports both pre-increment/decrement (`++x`, `--x`) and post-increment/decrement (`x++`, `x--`) operators.
-
-#### Post-increment (`x++`)
-The value of the expression is the value of `x` *before* the increment.
-```c
-int main() {
-    int x = 5;
-    int y = x++; // y is 5, x becomes 6
-    printf("x = %d, y = %d\n", x, y);
-    return 0;
-}
-```
-
-#### Pre-increment (`++x`)
-The value of the expression is the value of `x` *after* the increment.
-```c
-int main() {
-    int x = 5;
-    int y = ++x; // y is 6, x becomes 6
-    printf("x = %d, y = %d\n", x, y);
-    return 0;
-}
-```
-
-#### Post-decrement (`x--`)
-The value of the expression is the value of `x` *before* the decrement.
-```c
-int main() {
-    int x = 5;
-    int y = x--; // y is 5, x becomes 4
-    printf("x = %d, y = %d\n", x, y);
-    return 0;
-}
-```
-
-#### Pre-decrement (`--x`)
-The value of the expression is the value of `x` *after* the decrement.
-```c
-int main() {
-    int x = 5;
-    int y = --x; // y is 4, x becomes 4
-    printf("x = %d, y = %d\n", x, y);
-    return 0;
