C编程,错误:被调用对象不是函数或函数指针

我正在尝试编写一个实现Pop和Push功能的程序。问题是,我试图将指向整数Top的指针传递给函数,以便这个整数不断变化,但是当我尝试编译时,我总是得到这一行:

  

**错误:被调用对象不是函数或函数指针(* t) -

#include<stdio.h>
#include<stdlib.h>

#define MAX 10
int push(int stac[], int *v, int *t)
{
  if((*t) == MAX-1)
  {
      return(0);
  }
  else
  {
      (*t)++;
      stac[*t] = *v;
      return *v;
   }
}

int pop(int stac[], int *t)
{
 int popped;
 if((*t) == -1)
 {
      return(0);
 }
 else
 {
     popped = stac[*t]
     (*t)--;
     return popped;
 } 
}
int main()
{
int stack[MAX];
int value;
int choice;
int decision;
int top;
top = -1;
do{
   printf("Enter 1 to push the value\n");
   printf("Enter 2 to pop the value\n");
   printf("Enter 3 to exit\n");
   scanf("%d", &choice);
   if(choice == 1)
   {
       printf("Enter the value to be pushed\n");
       scanf("%d", &value);
       decision = push(stack, &value, &top);
       if(decision == 0)
       { 
           printf("Sorry, but the stack is full\n");  
       }
       else
       {
           printf("The value which is pushed is: %d\n", decision);
       }
   }
   else if(choice == 2)
    {
         decision = pop(stack, &top);
        if(decision == 0)
          {
               printf("The stack is empty\n");
          }
         else
          {
              printf("The value which is popped is: %d\n", decision);
          }

    }
 }while(choice != 3);
 printf("Top is %d\n", top);

}

答案 0 :(得分:16)

您错误地在该行之前错过了一个分号:

 poped = stac[*t] <----- here
 (*t)--;

这个奇怪错误的原因是编译器看起来像这样:

 poped = stac[*t](*t)--;

它可以解释为对来自表的函数指针的调用,但这显然没有意义,因为stac是一个int数组,而不是函数指针数组。
