﻿ C Program: Array from two array of integers of length 3

# C Exercises: Create a new array from two given array of integers of length 3

## C-programming basic algorithm: Exercise-47 with Solution

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);
arr_size2 = sizeof(nums2)/sizeof(nums2);

// 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, nums1, nums1, nums2, nums2, nums2 };

// 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
```
