# Konstruktory
|
||
- můžu přetěžovat, ale **POZOR**:
|
||
|
||
```
|
||
TridaA(void) //constructor pro inicializaci promenne
|
||
{
|
||
this->a = 0;
|
||
this->b = 0;
|
||
this->c = 0;
|
||
std::cout << "Byl zavolan konstruktor bez arg." << std::endl;
|
||
}
|
||
|
||
TridaA(int a) //inicializace z argumentu constructoru
|
||
{
|
||
this->a = a;
|
||
this->b = 0;
|
||
this->c = 0;
|
||
std::cout << "Byl zavolan konstruktor s arg." << std::endl;
|
||
}
|
||
|
||
TridaA(int a, int b = 42, int c = 64)
|
||
{
|
||
this->a = a;
|
||
this->b = b;
|
||
this->c = c;
|
||
}
|
||
```
|
||
|
||
Chyby kompilatoru:
|
||
```
|
||
main.cpp: In function ‘int main()’:
|
||
main.cpp:44:16: error: call of overloaded ‘TridaA(int)’ is ambiguous
|
||
44 | TridaA obj1(1); //inicializujeme objekt
|
||
| ^
|
||
main.cpp:44:16: note: there are 4 candidates
|
||
main.cpp:31:5: note: candidate 1: ‘TridaA::TridaA(int, int, int)’
|
||
31 | TridaA(int a, int b = 42, int c = 64)
|
||
| ^~~~~~
|
||
main.cpp:23:5: note: candidate 2: ‘TridaA::TridaA(int)’
|
||
23 | TridaA(int a) //inicializace z argumentu constructoru
|
||
| ^~~~~~
|
||
main.cpp:3:7: note: candidate 3: ‘constexpr TridaA::TridaA(const TridaA&)’
|
||
3 | class TridaA
|
||

|
||
main.cpp:3:7: note: candidate 4: ‘constexpr TridaA::TridaA(TridaA&&)’

```
