编程基于栈的操作实现将任意一个非负十进制数,打印输出与其等值的八进制数
一、第一种写法
代码如下(示例):
//Author:北硝 Date:2023.3.25
#include <stdio.h>
#include <stdlib.h>
//本程序主要实现功能说明
//编程基于栈的操作实现将任意一个非负十进制数,打印输出与其等值的八进制数;#define STACK_INIT_SIZE 100
#define STACK_INCREMENT 10
#define OK 1
#define ERROR 0
#define OVERFLOW -2
#define TRUE 1
#define FALSE 0typedef int SElemType;
typedef int Status;typedef struct {SElemType* base;SElemType* top;int stacksize;
} SqStack;Status InitStack(SqStack* S) {S->base = (SElemType*)malloc(STACK_INIT_SIZE * sizeof(SElemType));if (!S->base) {return OVERFLOW;}S->top = S->base;S->stacksize = STACK_INIT_SIZE;printf("栈初始化成功!\n");return OK;
}Status Push(SqStack* S, SElemType e) {if (S->top - S->base >= S->stacksize) {S->base = (SElemType*)realloc(S->base, (S->stacksize + STACK_INCREMENT) * sizeof(SElemType));if (!S->base) {return OVERFLOW;}S->top = S->base + S->stacksize;S->stacksize += STACK_INCREMENT;}*S->top++ = e;return OK;
}Status Pop(SqStack* S, SElemType* e) {if (S->top == S->base) {return ERROR;}*e = *--S->top;return OK;
}Status StackEmpty(SqStack S) {if (S.top == S.base) {return TRUE;}return FALSE;
}int main() {SqStack S;int N, e;InitStack(&S);printf("请输入一个十进制数:");scanf_s("%d", &N);while (N) {Push(&S, N % 8);N = N / 8;}printf("转换为八进制数为:");while (!StackEmpty(S)) {Pop(&S, &e);printf("%d", e);}printf("\n");return 0;
}

二、第二种写法
/Author:北硝 Date:2023.3.25
#include <stdio.h>
#include <stdlib.h>#define STACK_SIZE 50typedef struct {int top;int stack[STACK_SIZE];
} Stack;void initStack(Stack *s) {s->top = -1;
}void push(Stack *s, int value) {if (s->top >= STACK_SIZE - 1) {printf("Stack Overflow\n");return;}s->top++;s->stack[s->top] = value;
}int pop(Stack *s) {if (s->top < 0) {printf("Stack Underflow\n");exit(1);}int value = s->stack[s->top];s->top--;return value;
}int isEmpty(Stack *s) {return (s->top == -1);
}void printOctal(int num) {Stack s;initStack(&s);while (num != 0) {int remainder = num % 8;push(&s, remainder);num /= 8;}if (isEmpty(&s)) {printf("0");}while (!isEmpty(&s)) {int octalDigit = pop(&s);printf("%d", octalDigit);}
}int main() {int num;printf("请输入一个十进制数: ");scanf_s("%d", &num);printf("转换为八进制数为: ");printOctal(num);printf("\n");return 0;
}
