Linear Search in Array

Code

#include <stdio.h>
#include <stdint.h>

int linear_search(uint8_t *arr,uint8_t i, uint8_t n, uint8_t key) {
    // Your logic here

    if(n==i){
        return -1;
    }

    if(arr[i]== key){
        return i;
    }
    
    return linear_search(arr,i+1,n,key);
}

int main() {
    uint8_t n, key;
    scanf("%hhu", &n);
    uint8_t arr[100];
    for (uint8_t i = 0; i < n; i++) {
        scanf("%hhu", &arr[i]);
    }
    scanf("%hhu", &key);
    int i=0;
    int index = linear_search(arr,i, n, key);
    printf("%d", index);
    return 0;
}
