Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

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