搞不懂哪里出错了。大神指导指导
int 18,-43,34,max;
->
int a,b,c,max;
seanf("%d,%d,%d" ,&18,&-43,&,34);
->
scanf("%d,%d,%d" ,&a, &b, &c);
或者直接a=18, b = -43, c = 34;
max= C;
->
max= c;
完整程序
#include <stdio. h>
int main()
{
int a=18,b=-43,c=34,max;
max= a;
if (max<b)
max= b;
if (max<c)
max= c;
printf("The largest number is %d\n",max);
return 0;
}
注意一下C语言是严格区分字母大小写的，在用scanf时就可以实现输入三个数字，之间用逗号隔开，就赋值给a,b,c三个变量，不用直接去定义
#include<stdio.h>
int main()
{
int a,b,c,max;
printf(" please input three numbers:\n");
scanf("%d,%d,%d" ,&a,&b,&c);
max= a;
if (max<b)
max= b;
if (max<c)
max= c;
printf("The largest number is %d\n",max);
return 0;
}
