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>
int main(void){
int arr_size;
int a1[] = {10, 20, 30, 40, 50};
arr_size = sizeof(a1)/sizeof(a1[0]);
printf("Elements in original array are: ");
print_array(a1, arr_size);
int result[] = { a1[0], a1[arr_size - 1]};
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: 10, 20, 30, 40, 50 Elements in new array are: 10, 50

C Programming: Tips of the Day
How to increment a pointer address and pointer's value?
First, the ++ operator takes precedence over the * operator, and the () operators take precedence over everything else.
Second, the ++number operator is the same as the number++ operator if you're not assigning them to anything. The difference is number++ returns number and then increments number, and ++number increments first and then returns it.
Third, by increasing the value of a pointer, you're incrementing it by the sizeof its contents, that is you're incrementing it as if you were iterating in an array.
