linear search array for key and return index of first
occurrence.

False. In a binary search, if the search fails on the first trial of an array of 1000 elements, then there are only nine more elements left to search.
You cannot delete elements from an array. But you can move the elements: if (del_index < no_of_elements-1) { memmove (&array [del_index], &array [del_index+1], sizeof (array [0]) * (no_of_elements - del_index - 1)); } --no_of_elements;
An aggregate of elements of the same type that occupy contiguous memory.
int array[10] = {...}; for (int i = 0; i < 10; ++i) { if (i % 2 == 0) array[i] += 5; else array[i] -= 10; }
A binary search is much faster.

Logic to search element in array Input size and elements in array from user. ... Input number to search from user in some variable say toSearch . Define a flag variable as found = 0 . ... Run loop from 0 to size . ... Inside loop check if current array element is equal to searched number or not. To learn more about data science please visit- Learnbay.co
The best search algorithm to use for an unsorted array is linear search. It involves checking each element in the array one by one until the desired element is found. This algorithm has a time complexity of O(n), where n is the number of elements in the array.
To search, you would start with the first element of the array and compare it with the target value. If the first element matches the target, you found it. If not, you would move to the next element in the array and repeat the process until either you find the target or exhaust all elements in the array.
#include "stdio.h" #define SIZE 100; void main() { int array[SIZE], i, size; printf("\nEnter the Size off Array :- "); scanf("%d", &size); printf("\nEnter the Elements of Array :- ")' for(i = 0; i < size; i++) scanf("%d", &array[i]; printf("\nThe Elements of entered Array :- "); for(i = 0; i < size; i++) printf("%7d", array[i]); }
Look at the definition, http://en.wikipedia.org/wiki/Lucky_number , then create an array of integers and start working on it. The sieve method requires you to eliminate certain numbers; you can either replace the eliminated array elements with a marker, or move the non-eliminated elements towards the beginning of the array (overwriting the eliminated elements), or perhaps copy to a different array - depending on whether you want simplicity in programming (putting a marker, such as 0, is probably easier to program), or efficiency.Look at the definition, http://en.wikipedia.org/wiki/Lucky_number , then create an array of integers and start working on it.

In a binary search algorithm, typically log(n) comparisons are made when searching for a specific element in a sorted array, where n is the number of elements in the array.
