How to perform linear search (sequential search) in C

Answer 1

#include <stdio.h>

int Linear_Search(int* arr, int size, int data) {
	for (int i = 0; i < size; i++) {
		if (data == arr[i]) return i;
	}

	return -1;
}

int main(void) {
    int arr[] = { 4, 9, 78, 99, 10, 1200, 300 };
    int size = sizeof(arr) / sizeof(arr[0]);
    
    int index = Linear_Search(arr, size, 99);
    
    printf("%d", index);
    
    return 0;
}
