C Exercises: Check whether an array is subset of another array
C Array: Exercise-55 with Solution
Write a program in C to check whether an array is a subset of another array.
Pictorial Presentation:

Sample Solution:
C Code:
#include <stdio.h>
int chkSubsetArray(int *arr1 , int arr1_size, int *arr2, int arr2_size)
{
int i, j;
for (i = 0; i < arr2_size; i++)
{
for (j = 0; j < arr1_size; j++)
{
if(arr2[i] == arr1[j])
break;
}
if(j == arr1_size)
return 0;
}
return 1;
}
int main()
{
int arr1[] = {4, 8, 7, 11, 6, 9, 5, 0, 2};
int arr2[] = {5, 4, 2, 0, 6};
int n1 = sizeof(arr1)/sizeof(arr1[0]);
int i;
int n2 = sizeof(arr2)/sizeof(arr2[0]);
//------------- print first array ------------------
printf("The given first array is : ");
for(i = 0; i < n1; i++)
{
printf("%d ", arr1[i]);
}
printf("\n");
//------------- print second array ------------------
printf("The given second array is : ");
for(i = 0; i < n2; i++)
{
printf("%d ", arr2[i]);
}
printf("\n");
//------------------------------------------------------
if(chkSubsetArray(arr1, 9, arr2, 4))
printf("The second array is the subset of first array.");
else
printf("The second array is not a subset of first array");
return 0;
}
Sample Output:
The given first array is : 4 8 7 11 6 9 5 0 2 The given second array is : 5 4 2 0 6 The second array is the subset of first array.
