// Post-increment Operator Demonstration
#include <stdio.h>

int main() {
    // Step 1: Initialize a variable
    int a = 10;
    printf("Initial a: %d\n", a);

    // Step 2: Use post-increment in an expression
    int b = a++; // 'a's original value (10) is assigned to 'b', then 'a' is incremented to 11
    printf("After b = a++;\n");
    printf("a: %d\n", a); // a is 11
    printf("b: %d\n", b); // b is 10

    return 0;
