C Exercises: Create a new array taking the elements before the element value 5 from a given array of integers

C-programming basic algorithm: Exercise-69 with Solution

Write a C program to create a new array taking the elements before the element value 5 from a given array of integers.

C Code:

#include <stdio.h>
#include <stdlib.h>
int main(void){ 
    int arr_size;
    int a1[] = {1, 2, 3, 5, 7};
    arr_size = sizeof(a1)/sizeof(a1[0]);
    printf("Elements in original array are: ");  
    print_array(a1, arr_size);
    int size = 0;
    int pre_ele_5[arr_size];
     for (int i = 0; i < arr_size; i++)
        {
           if (a1[i] == 5)
              {
                size = i;
                break;
                }
            }
       int result[size];

            for (int j = 0; j < size; j++)
            {
                result[j] = a1[j];
            }
    arr_size = sizeof(result)/sizeof(result[0]);                
    printf("\nElements in new array are: ");  
    print_array(result, arr_size);
    }     
 print_array(int parray[], int size)
  {
   int i;      
   for( i=0; i<size-1; i++)  
    {  
        printf("%d, ", parray[i]);  
    } 
   printf("%d ", parray[i]);  
   printf("\n");   
  }

Sample Output:

Elements in original array are: 1, 2, 3, 5, 7 

Elements in new array are: 1, 2, 3
