Question

C++ "already has a body"

Answer 1

重复定义函数了啊.max1和max2定义了两次

int max1(int x,int y);

int max2(int x,int y);

main()

{

int a,b,c;

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

printf("max=%d",max2(max1(a,b),c));

}

int max1(int x,int y)

{ int d

d=x>y?x:y;

return d;

}

int max2(int x,int y)

{ int c

c=x>y?x:y;

return c;

}
