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。
