Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>


int find_pattern(int *mem, int n) 
{
    int *ptr = mem;
    for(int i =0;i<n;i++)
    {
        //if (*(ptr + 1) == *ptr + 1 && *(ptr + 2) == *(ptr + 1) + 1)
    

        if(*(ptr + 1) == *ptr +1  &&  *(ptr+2) == *(ptr+1)+1)
        {
            return i;
        }
        ptr++;
        
    }
    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;
}
