微信小程序border-radius不圆滑

相信大家都有过通讯录，今天我来带大家实现以下最简单的通讯录，通过本篇文章，相信可以让大家对C语言有进一步的认识。

话不多说，我们先放函数的实现

#define  _CRT_SECURE_NO_WARNINGS 1
#include "Contact.h"


int CheakCapacity(Contact* ps);

void LoadContact(Contact* ps)
{
	FILE* pf = fopen("Contact.dat", "rb");
	if (pf == NULL)
	{
		perror("LoadContact");
		return;
	}
	PeoInfo tmp = { 0 };
	while (fread(&tmp,sizeof(PeoInfo),1,pf))
	{
		CheakCapacity(ps);
		ps->date[ps->size] = tmp;
		ps->size++;
	}

	fclose(pf);
	pf = NULL;

	
}

void InitContact(Contact* ps)
{
	assert(ps);
	ps->date = NULL;
	ps->size = ps->capacity = 0;
	LoadContact(ps);
}

int CheakCapacity(Contact* ps)
{
	assert(ps);
	if (ps->capacity == ps->size)
	{
		int newcapacity = ps->capacity == 0 ? 4 : ps->capacity * 2;
		PeoInfo* tmp = (PeoInfo*)realloc(ps->date, newcapacity * sizeof(PeoInfo));
		if (tmp == NULL)
		{
			perror("CheakCapacity");
			return 0;
		}
		else
		{
			ps->date = tmp;
			ps->capacity = newcapacity;
			printf("增容成功\n");
			return 1;
		}
	}
	return 1;
}

void AddContact(Contact* ps)
{
	assert(ps);
	if (CheakCapacity(ps) == 0)
	{

	}

	printf("请输入增加的姓名:>");

 是不是看到这里会感到很害怕？？不用怕，跟着我的思路，你也可以实现它，我带着你一步一步实现每一个功能

 是不是发现其实函数的实现很多都是相似的， 所以不用怕，接着往后看。
