Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    int start_index=0,found = 0;
    while(!found && start_index<=n-3){
        if((((*mem)+1) == (*(mem+1))) && (((*(mem+1))+1) == (*(mem+2)))){
            found = 1;
        }
        if(found){
            return start_index;
        }
        start_index+=1;
        mem++;    
    }
    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;
}
