int* (*a[5])(int, char*);
帶指針返回的函數(shù)指針數(shù)組
int *：函數(shù)返回值的類型是一個指針變量
(*a[5])：函數(shù)指針名為a，共有5個元素
(int, char*)：帶有兩個參數(shù)int型參數(shù)和char指針型參數(shù)
如：

int *fc(int a, char *c)
{
  static char cc[0];
  cc[0] = c[0] + a;
  cc[1] = c[1] + a;
  ...
  ...
  cc[9] = c[9] + a;
  return cc;
}

a[0] = fc; //給指針函數(shù)第0個元素賦值
char buf[10] = {0,1,2,3,4,5,6,7,8,9};
a[0](5, buf); //運行指針函數(shù)，等于直接運行fc函數(shù)
