动态栈的实现:
定义头文件:
#include<stdio.h> #include<stdlib.h> #include<string.h> int *stack; int top=-1; int capacity=1; void push(int ele); int pop(); void stackEmpty(); void stackFull();
动态栈函数的操作:
void push(int ele){ if(top==capacity-1){ stackFull(); } stack[++top]=ele; } int pop(){ if(top<0){ stackEmpty(); } return stack[top--]; } void stackFull(){ realloc(stack,2*capacity*sizeof(int*)); capacity*=2; } void stackEmpty(){ fprintf(stderr,"stack is empty!"); exit(EXIT_FAILURE); }
主函数测试:
int main(void) { stack=malloc(sizeof(int*)); push(3); printf("%d\n",pop()); pop(); return 0; }
