sum of numbers in malloc numbers

-

 

  1. #include<stdio.h>  
  2. #include<stdlib.h>  
  3. int main(){  
  4.   int n,i,*ptr,sum=0;    
  5.     printf("Enter number of elements: ");    
  6.     scanf("%d",&n);    
  7.     ptr=(int*)malloc(n*sizeof(int));  
  8.     if(ptr==NULL)                         
  9.     {    
  10.         printf("Sorry! unable to allocate memory");    
  11.         exit(0);    
  12.     }    
  13.     printf("Enter elements of array: ");    
  14.     for(i=0;i<n;++i)    
  15.     {    
  16.         scanf("%d",ptr+i);    
  17.         sum+=*(ptr+i);    
  18.     }    
  19.     printf("Sum=%d",sum);    
  20.     free(ptr);     
  21. return 0;  
  22. }    

Output

Enter elements of array: 3
Enter elements of array: 10
