Question

This program will be graded based on whether the required functionality were implemented correctly instead of whether it produces the correct output. Modify the program; the insert0 detection function using pointer arithmetic. The function prototype should be the following

void insert0(int n, int *a1, int *a2);

The function should use pointer arithmetic – not subscripting – to visit array elements. In other words, eliminate the loop index variables and all use of the [] operator in the function

#include

void insert0(int n, int a1[], int a2[]);

int main(void)
{
int i;

int N;

printf("Please enter the length of the input array: ");
scanf("%d", &N);

int a[N];
int b[2*N];

printf("Enter %d numbers for the array: ", N);
for (i = 0; i < N; i++)
scanf("%d", &a[i]);

insert0(N, a, b);

printf("Output array:");
for (i = 0; i < 2*N; i++)
printf(" %d", b[i]);
printf(" ");

return 0;

}

void insert0(int n, int a[], int b[])
{

int i, j = 0;
for(i = 0; i < n; i++, j+=2){
b[j]= a[i];
b[j+1] = 0;
}

}

Explanation / Answer

Please refer below program for highlighted changes.

#include<stdio.h>
void insert0(int n, int *a1, int *a2);

int main(void)
{
int i;
int N;
printf("Please enter the length of the input array: ");
scanf("%d", &N);
  
int a[N];
int b[2*N];
printf("Enter %d numbers for the array: ", N);
  
for (i = 0; i < N; i++)
scanf("%d", &a[i]);
  
insert0(N, a, b);
  
printf("Output array:");
for (i = 0; i < 2*N; i++)
printf(" %d", b[i]);
  
printf(" ");
return 0;
}

void insert0(int n, int *a, int *b)
{
int i, j = 0;
for(i = 0; i < n; i++, j+=2){
*(b+j) = *(a+i);
*(b+j+1) = 0;
}
}

OUTPUT:

Please enter the length of the input array: 4

Enter 4 numbers for the array: 1 2 3 4

Output array: 1 0 2 0 3 0 4 0
