Question

Programming language question ( please help if you can )

write a function f1() with the following requirements (in C language):

- It must define a local array of char values. The size must be adjustable via define macro. The default size could be, say, 1000.

- It must also define a static int n that increments the number of activation records.

- It must also define a static long int addr that stores the starting address of the array.

- Then it must print the current activation record number, the memory address of the current array, followed by the estimated size of the current activation record as a distance between the current array address and the array address from the previous activation record.

Answer 1

#include <stdio.h>
#define SIZE 1000

void f1(){

char values[SIZE];
static int n = 0;
long int addr = (long int )&values[0];
n++;
printf("current activation record number is %d\n",n);
addr = (long int )&values[n];
printf("The memory address of the current array is: %d\n",addr);
printf("The estimated size of current activation record is : %d\n",((long int)&values[n] - (long int)&values[n-1]));

}

void main()
{

f1();
f1();
}

// Output
