C Exercises: Check a given array of integers and return true if there is a 3 with a 5 somewhere later in the given array

C-programming basic algorithm: Exercise-62 with Solution

Write a C program to check a given array of integers and return true if there is a 3 with a 5 somewhere later in the given array.

C Code:

#include <stdio.h>
#include <stdlib.h>

int main(void){
    int arr_size;
    int array1[] = {1, 2, 3, 4 };
    arr_size = sizeof(array1)/sizeof(array1[0]);
    printf("%d",test(array1, arr_size));
    int array2[] = {3, 3, 5, 5, 5, 5};
    arr_size = sizeof(array2)/sizeof(array2[0]);
    printf("\n%d",test(array2, arr_size));
    int array3[] = {2, 5, 5, 7, 8, 10};
    arr_size = sizeof(array3)/sizeof(array3[0]);
    printf("\n%d",test(array3, arr_size));
  }
    
  int test(int numbers[], int arr_size)
         {
            int three = 0;

            for (int i = 0; i < arr_size; i++)
            {
                if (three && numbers[i] == 5) return 1;
                if (numbers[i] == 3) three = 1;
            }
            return 0;
         }

Sample Output:

0
1
0
