c语言程序如何编写选择题,c语言程序 如何编写挑选题

呵呵，很简单的问题呀，我这里有四种方法，你参考一下

#include

void main()

{

int a,b,c,max; //这里只能为整形，不能为double型

printf("please input three number a,b,c:\n");

scanf("%d%d%d",&a,&b,&c);

// method one:

max=a;

if(b>=max) max=b;

if(c>=max) max=c;

printf("the max is:%d\n",max);

// method two:

if(a>=b&&a>=c)

printf("the max is %d\n",a);

else if(b>=a&&b>=c)

printf("the max is %d\n",b);

else

printf("the max is %d\n",c);

// method three:

printf("the max is: %d\n",a>=b&&a>=c?a:(b>=a&&b>=c?b:c));

// method four:

int a[3],max=-32768;

for(int i=0;i<3;i++)

{

scanf("%d",&a[i]);

if(a[i]>max) max=a[i];

}

printf("the max is:%d\n",max);

}
