Question

我有这种结构

typedef struct
{
    int numberPipes;              // |
    int numberAmpersands;         // &
    int existsBiggerThan;         // >
    int existsLessThan;           // <
    int existsDoubleLargerThan;   // >>

} lineData;

and I run in my loop on a char array (char*), in order to find all indexes of & and | .

I don t know how much & and | I m going to find . Is it possible to start with two arrays (using malloc) of size 1 and enlarge them after each iteration , only if I find another occurrence of one of them ?

Answer 1

可以通过打电话realloc。

由于业绩原因,最好不要针对每个新内容,而是在X部分中一次,这样,你就可以减少打到<代码>小型<<>>/代码>/<代码>realloc的电话号码。
