c语言初学者的答案：
#include <stdio.h>
int main(int argc, char *argv[])
{
int a,b,c,max,max1;
scanf("%d", &a);
scanf("%d", &b);
scanf("%d", &c);
max1=a>b?a:b;
max=max1>c?max1:c;
printf("%d",max);
}

c++答案
#include <iostream>
#include <cmath>
using namespace std;
int main()
{
int a,b,c;
cin>>a>>b>>c;
if(a<b){
if(b<c){cout<<c<<endl;
}
else{cout<<b<<endl;}
}
else{cout<<a<<endl;}

getchar();
getchar();
return 0;
}

#include <stdio.h>

a=int(input())
b=int(input())
c=int(input())

max=a
if b>max:
max=b
if c>max:
max=c

print(max)

a=int(input())
b=int(input())
c=int(input())

if( and ):
print()
elif( and ):
print()
elif( and ):
