Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    int *p= mem;
    int i=0;
    for(i=0;i<n-2;i++){
       if (*(p+1)==*p+1 && *(p+2)== *p+2){
        return i;
       }
        p++;
    }

    return -1;
}

int main() {
    int n, arr[100];
    scanf("%d", &n);

    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    int res = find_pattern(arr, n);
    printf("%d", res);

    return 0;
}
