Increment and Decrement Operators

Increment and decrement operators are used to increase or decrease the value of a variable by one, respectively. The increment operator is `++` and the decrement operator is `--`.

• Increment (++): Increases the value by one.
• Decrement (--): Decreases the value by one.

#include <stdio.h>
int main() {
    int a = 5;
    a++; // Increment
    printf("Value of a after increment: %d\n", a);
    return 0;
}

#include <stdio.h>
int main() {
    int a = 5;
    a--; // Decrement
    printf("Value of a after decrement: %d\n", a);
    return 0;
}
