[問題] Array特殊用法?
#include <stdio.h>
long Add(int x, int b)
{
return x + b ;
}
long Sub(int x, int b)
{
return x - b;
}
long Mul(int x, int b)
{
return x * b;
}
long int (*calc[3]) (int, int);//this array
void main()
{
calc[0] = Add;
calc[1] = Sub;
calc[2] = Mul;
printf("Item 0 return %d\n", (*calc[0])(5,10));
printf("Item 1 return %d\n", (*calc[1])(5,10));
printf("Item 2 return %d\n", (*calc[2])(5,10));
}
這邊我想請問，程式碼中間calc的宣告"long int(*calc[3])(int, int)"這個是什麼
特殊用途?謝謝。
