Write a C program to create a new array from two given arrays of integers, each of length 3.

C Code:

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

// Function prototype for 'print_array'
void print_array(int parray[], int size);

int main(void){
    // Declaration and initialization of variables
    int new_arr_size = 6; // Size of the new array
    int arr_size1, arr_size2; // Sizes of the original arrays

    // Declaration and initialization of the original arrays 'nums1' and 'nums2'
    int nums1[] = {10, 20, 30};
    int nums2[] = {40, 50, 60};

    // Calculating the size of the original arrays
    arr_size1 = sizeof(nums1)/sizeof(nums1[0]);
    arr_size2 = sizeof(nums2)/sizeof(nums2[0]);

    // Printing elements in the first original array
    printf("Elements in original array1 are: ");  
    print_array(nums1, arr_size1);

    // Printing elements in the second original array
    printf("Elements in original array2 are: "); 
    print_array(nums2, arr_size2);

    // Creating a new array by combining elements from the original arrays
    int result[] = { nums1[0], nums1[1], nums1[2], nums2[0], nums2[1], nums2[2] };

    // Printing elements in the new array
    printf("New array: ");  
    print_array(result, new_arr_size);        
}  

// Definition of the 'print_array' function
void print_array(int parray[], int size)
{
    int i;      
    for( i=0; i<size-1; i++)  
    {  
        // Printing each element with a comma and a space
        printf("%d, ", parray[i]);  
    } 
    // Printing the last element without a comma and space
    printf("%d ", parray[i]);  
    // Printing a new line to separate the elements
    printf("\n");   
}

Sample Output:

Elements in original array1 are: 10, 20, 30 
Elements in original array2 are: 40, 50, 60 
New array: 10, 20, 30, 40, 50, 60
