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

C-programming basic algorithm: Exercise-70 with Solution

Write a C program to create a new array taking the elements after 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, 9, 11};
    arr_size = sizeof(a1)/sizeof(a1[0]);
    printf("Elements in original array are: ");  
    print_array(a1, arr_size);
    
    int size = 0;
    int len = arr_size;
    int i = len - 1;
    while (i >= 0 && a1[i] != 5) i--;
    i++;
    size = len - i;
    int post_ele_5[size];
    for (int j = 0; j < size; j++)
      {
          post_ele_5[j] = a1[i + j];
      }    
    arr_size = sizeof(post_ele_5)/sizeof(post_ele_5[0]);                
    printf("\nElements in new array are: ");  
    print_array(post_ele_5, 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, 9, 11 

Elements in new array are: 7, 9, 11
