C Exercises: Create a new array taking the first and last elements of a given array of integers and length one or more

C-programming basic algorithm: Exercise-40 with Solution

Write a C program to create a new array taking the first and last elements of a given array of integers and length one or more.

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 arr_size;
    int a1[] = {10, 20, 30, 40, 50};

    // Calculating the size of the array
    arr_size = sizeof(a1)/sizeof(a1[0]);

    // Printing elements in the original array
    printf("Elements in original array are: ");  
    print_array(a1, arr_size);

    // Creating a new array with the first and last elements from the original array
    int result[] = { a1[0], a1[arr_size - 1]};

    // Calculating the size of the new array
    arr_size = sizeof(result)/sizeof(result[0]);

    // Printing elements in the new array
    printf("\nElements in new array are: ");  
    print_array(result, 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 array are: 10, 20, 30, 40, 50 

Elements in new array are: 10, 50

C Programming Code Editor:

Previous: Write a C program to create a new array containing the middle elements from the two given arrays of integers, each length 5.
Next: Write a C program to check if a given array of integers and length 2, contains 15 or 20.
