用scanf 或scanf_s都报错

Question

#include<stdio.h>
#include<windows.h>
#include

int main()
{
char ch1, ch2, ch3;
scanf("%c%c%c", &ch1, &ch2, &ch3);
printf("%c,%d\n", ch3, ch3);
printf("%c,%d\n", ch2, ch2);
printf("%c,%d\n", ch1, ch1);
system(“pause”);
}

#include<stdio.h>
#include<windows.h>
#include

int main()
{
int num1, num2, num3;
float average;
printf(“Please input three numbles:”);
scanf("%d,%d,%d",&num1,&num2,&num3)/3.0;
printf(“average=%7.2f\n”, average);
}

这两个代码运行报错，需要怎么解决

  '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.

  已经很清楚告诉你了，最好把scanf换成scanf_s函数，否则需要修改编译设置。
