VS2019：严重性代码说明项目文件行禁止显示状态错误C4996:‘scanf‘: This function or variable may be unsafe

1.运行报错严重性 代码 说明 项目 文件 行 禁止显示状态错误：C4996 ‘scanf’: This function or variable may be unsafe. Consider using scanf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

2.关闭项目属性“SDL检查”

3.顺利运行通过

4.附上图片的完整测试代码(猜数字)

#include "stdio.h"
#include "conio.h"

void main()
{
	int Password=0,Number=0,price=58,i=0;

	while( Password != 12345 )
	{
		if( i >= 3 )
			return;
		i++;
		puts("Please input Password: ");
		scanf("%d",&Password);
	}

	i=0;
	while( Number!=price )
	{
		do{
			puts("Please input a number between 1 and 100: ");
			scanf("%d",&Number);
			printf("Your input number is %d\n",Number);
		}while( !(Number>=1 && Number<=100) );
		if( Number >= 90 )
		{
			printf("Too Bigger! Press any key to try again!\n");
		}
		else if( Number >= 70 && Number < 90 )
		{
			printf("Bigger!\n");
		}
		else if( Number >= 1 && Number <= 30 )
		{
			printf("Too Small! Press any key to try again!\n");
		}
		else if( Number > 30 && Number <= 50 )
		{
			printf("Small! Press any key to try again!\n");
		}
		else
		{
			if( Number == price )
			{
				printf("OK! You are right! Bye Bye!\n");
			}
			else if( Number < price )
			{
				printf("Sorry,Only a little smaller! Press any key to try again!\n");

			}
			else if( Number > price )
				printf(" Sorry, Only a little bigger! Press any key to try again!\n");
		}
		getch();
	}
}

还有其他方法（来自网络）

方法2：在程序最前面加，#pragma warning(disable:4996)；
方法3：scanf改为scanf_s；
方法4：在程序最前面加，“#define_CRT_SECURE_NO_WARNINGS；”或者“ #define _CRT_SECURE_NO_DEPRECATE；”
方法5：在项目属性 ‘c/c++ ’命令行添加：
“/D _CRT_SECURE_NO_WARNINGS ”。
