Question

Create C program that takes 1 parameter: a number.

Using that number, dynamically allocate a memory so you store that number of integers.

Write integers in order starting from 1 until you fill all that memory.

Print the addresses and values of the first and the last integer stored in the memory.

Answer 1

HERE IS THE CODE AS PER YOUR REQUIREMENT

CODE:

#include<stdio.h>
#include<stdlib.h>

int main() {
int n,i;
// pointer to hold base address of the block to be created
int* ptr;
// user input for a number parameter
printf("Enter the number of elements: ");
scanf("%d",&n);
// malloc method to dynamically allocate the memory
ptr = (int*)malloc(n * sizeof(int));
if(ptr != NULL) {
// Entering the elements from 1 to n into the memory locations
printf("Memory allocated successfully using malloc() method");
for (int i = 0; i < n; i++) {
ptr[i] = i+1;
}
// printing the values and assigned addresses of 1st and last integer stored
printf("\n%d %p",ptr[0],&ptr[0]);
printf("\n%d %p",ptr[n-1],&ptr[n-1]);
}
else {
printf("Memory not allocated");
  
}
}
