// Pre-decrement Operator Demonstration
#include <stdio.h>

int main() {
    // Step 1: Initialize a variable
    int p = 15;
    printf("Initial p: %d\n", p);

    // Step 2: Use pre-decrement in an expression
    int q = --p; // p is decremented to 14, then its new value (14) is assigned to q
    printf("After q = --p;\n");
    printf("p: %d\n", p); // p is 14
    printf("q: %d\n", q); // q is 14

    return 0;
