Question

C Programming:

Write a function that takes a size DIM array of double's as input and sets every value in the array to zero.

If not too much trouble, please annotate your work (so I'm learning and not just blindly copying), thankyou

The exact info I was given is shown below. I have not idea what size DIM array means.

arrayZero Function The first function you need to write this week is extremely simple. I takes a size DIM array of double's as input, and sets every value in the array to zero. This is a very small function and should be quite easy, however it will give you important practice in accessing each dimension of a vector.

Answer 1

#include <stdio.h>
#include<malloc.h>

int main(void)
{
void set(double *,int); //function prototype takes integer and DIM
double *arr;
int dim;
printf("\n Enter the DIMENSION of the array");
scanf("%d",&dim); //Enter the dimension of array
arr=(double *)malloc(dim*sizeof(double)); //dynamically allocate the array
set(arr,dim); //call the function to assign the values to 0
return 0;
}
void set(double *arr,int n)
{
int i;
for(i=0;i<dim;i++) //Loop to access each element of array
*(arr+i)=0; //array 0 to all the elements of array
printf("\n The array elements are");
for(i=0;i<dim;i++)
printf(" %lf",*(arr+i)); //display the elements of array after assign to 0
}
