C Program to perform Linear Search, Linear Search basically iterates from start to end in order to find the key element.

#include<stdio.h>

int main(){
    
    
    int search_array[] = {4,1,56,7,10,71,63,17,2,3};
    
    int key = 17; //Element to search
    
    int i, size = sizeof(search_array)/sizeof(search_array[0]);
    int found = 0, position;

    for(i = 0 ; i < size; i++){
        if(search_array[i] == key){
            found = 1;
            position = i;
            break;
        }
    }
    
    
    if(found){
        printf("Element %d found at position %d",key,position);
    }else{
        printf("Element not found");
    }
    

    return 0;

}

Element 17 found at position 7
