Ein Vortrag von Timon Stampfli auf der GPN19.
C++ / Snake Programming Workshop
There will be 2 parts. In the first part we will talk about the C++ specifics that are useful for writing a snake game bot. Things like - Strings (C-Strings and C++ STL Strings) aka how do I log something - STL Datastructures aka how do I resize my array - Whatever you want to know about C++
In the second part we can discuss some snake bot strategies or algorithms. Your participation, questions is the basis for this part
This is not a introduction into programming but learning to use C++ for writing snake bots for creatures already familiar with another programming language.

#include <bits/stdc++.h>
using namespace std;
void log(string str, Api* api){
api->log(str.c_str());
}
bool step(Api* api) {
api->log(string("Hello C-String World"));
string str="Debug Value1: ";
str+= 3 + ", some more text";
log(string("some string") + 5.1);
log(string()+3);
}
ich mache das:
string logtxt = "bla" + to_string(irgendeine integer variable);
api->log(logtxt.c_str());
int main(){
vector<int> vec(10,20);
vec.push_back(200);
}
/* C-Arrays: Legacy DO NOT USE */
int main(){
int some_array[23] = {5,2,3};
some_array[103];
*(some_array + 3)
return 0;
}
void caller(){
int a = 23;
call_by_value(a);
call_by_adress(&a);
// a is now 24
call_by_reference(a);
// a is now 25
}
void call_by_value(int a){
a++;
}
void call_by_adress(int * a){
(*a)++;
}
void call_by_reference(int& a){
a++;
}
api.functions_name();
(*api).funktions_name();
api->funktions_name();
ist das da in Ordnung?
Ich habe so meine Probleme mit Pointer, vectoren in funktionen...
void add(vector<int> *clc, int pos, int add)
{
(*clc)[pos] += add;
}
