int main() {
    int *p = 15;
    printf("%d", *p);
}

1. #include <stdio.h>: This line includes the standard input-output library, which is necessary for using functions like printf.

2. int main() {: This line declares the beginning of the main function, which is the entry point of every C program.

3. int *p = 15;: This line declares a pointer variable p that is intended to store the memory address of an integer. However, it initializes the pointer with the value 15, which is not a memory address but an integer value.

4. printf("%d", *p);: This line attempts to print the value pointed to by the pointer p. However, since p is initialized with the integer 15, and not a valid memory address, it results in undefined behavior. The program may crash or produce unexpected output.
