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

#include<stdio.h>


void fun(int n){
  int *ptr = (int*) malloc(n * sizeof(int));
  for(int i=0;i<n;i++){
    ptr[i]=i+1;
  }
  printf("First  ->\nAddress: %p \n value: %d\n",&ptr[0],ptr[0]);
  printf("Last  ->\nAddress: %p \n value: %d",&ptr[n-1],ptr[n-1]);
}
int main() {

fun(10);
}
