蓝桥杯 基础练习（查找整数）

坑点
记得若不存在，就要输出-1

# include

int main()
{
    int n;
    scanf("%d", &n);

    int a[n];
    int i, obj, ret;

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

    scanf("%d", &obj);

    ret = -1;
    for(i=0; i<n; i++){
        if(a[i] == obj){
            printf("%d",i+1);
            ret = 0;
            break;
        }
    }

    if(ret == -1){
        printf("-1");
    }

    return 0;
}
