# Oh my god programming language # Oh my god programming language
Питонисты плакали когда увидели это! Питонисты плакали когда увидели это!
Реализован язык с типами int string. Я могу создавать переменные в любой степени вложенности, они корректно убираются со стека. Также корректно работает приоритет операций. Пример кода на моем языке:
```c++
string s = "abacaba ";
for (int i = 0; i < 5; i += 1) {
string t = "";
for (int j = 0; j < 3; j += 1) {
t += "t";
}
s += t;
print(s);
}
int x = (1 + 2) * 3;
print(x, x + 1, x + 2);
print(7777);
while (x != 0) {
x -= 1;
}
print(x);
```
Результат работы:
```text
abacaba ttt
abacaba tttttt
abacaba ttttttttt
abacaba tttttttttttt
abacaba ttttttttttttttt
9 10 11
7777
0
END
```
