Question

c语言中的代码问题：为什么运行是总是提示declaration syntax error

# include"stdio.h"
void main()
{
int max(int a,int b);
int a,b,c;
printf("input two numbers\n");
scanf("%d,%d",&a,&b);
c=max(a,b);
printf("the bigger number is \n",c);
}
int max(int m,int n);
{
int s;
s=m>n ? m: n;
return(s);
}

Answer 1

int max(int m,int n); 定义后面不要写分号

Answer 2

# include"stdio.h"
void main()
{
int max(int a,int b);
int a,b,c;
printf("input two numbers\n");
scanf("%d,%d",&a,&b);
c=max(a,b);
printf("the bigger number is %d\n",c); ////////////////////missing a %d
}
int max(int m,int n)///////////remove a ;
{
int s;
s=m>n ? m: n;
return(s);
}
