POPIS NAPRIJED U C ++ | POSTAVITE 2 (MANIPULIRANJE FUNKCIJA)

Popis naprijed u C ++ | Set 1 (uvod i važne funkcije) Više funkcija raspravlja se u ovom članku, neke od operacija osim umetanja i brisanja koje se mogu koristiti na popisima naprijed su sljedeće:

1. spojiti() :- Ova se funkcija koristi za spajanje jednog popisa prema naprijed s drugim. Ako su oba popisa razvrstana, tada se razvrstava i rezultirajući popis.

2. Operator '=' :- Ovaj operater kopira jedan popis naprijed u drugi. Kopija napravljena u ovom slučaju je duboka kopija.

CPP

// C++ code to demonstrate the working of  // merge() and operator=  #include    #include  using namespace std;  int main()  {   // Initializing 1st forward list   forward_list<int> flist1 = {1 2 3};     // Declaring 2nd forward list   forward_list<int> flist2;     // Creating deep copy using '='   flist2 = flist1;     // Displaying flist2   cout << 'The contents of 2nd forward list'  ' after copy are : ';   for (int &x : flist2)   cout << x << ' ';   cout << endl;     // Using merge() to merge both list in 1   flist1.merge(flist2);     // Displaying merged forward list   // Prints sorted list   cout << 'The contents of forward list '  'after merge are : ';   for (int &x : flist1)   cout << x << ' ';   cout << endl;     return 0;  }

3. vrsta() :- Ova se funkcija koristi za sortiranje popisa naprijed.

4. Jedinstveno () :- Ova funkcija briše višestruke pojave broja i vraća popis naprijed s jedinstvenim elementima. Popis naprijed treba razvrstati da se ova funkcija uspješno izvrši.

CPP

// C++ code to demonstrate the working of  // sort() and unique()  #include    #include // for sort() and unique()  using namespace std;  int main()  {   // Initializing 1st forward list   forward_list<int> flist1 = {1 2 3 2 3 3 1};   // Sorting the forward list using sort()   flist1.sort();   // Displaying sorted forward list   cout << 'The contents of forward list after '  'sorting are : ';   for (int &x : flist1)   cout << x << ' ';   cout << endl;   // Use of unique() to remove repeated occurrences   flist1.unique();   // Displaying forward list after using unique()   cout << 'The contents of forward list after '  'unique operation are : ';   for (int &x : flist1)   cout << x << ' ';   cout << endl;   return 0;  }

Izlaz:

The contents of forward list after sorting are : 1 1 2 2 3 3 3 The contents of forward list after unique operation are : 1 2 3

5. obrnuto () :- Ova se funkcija koristi za preokret popisa naprijed.

6. SWAP () :- Ova funkcija zamjenjuje sadržaj jednog popisa naprijed s drugim.

CPP

// C++ code to demonstrate the working of  // reverse() and swap()  #include    #include // for reverse() and swap()  using namespace std;  int main()  {   // Initializing 1st forward list   forward_list<int> flist1 = {1 2 3};   // Initializing 2nd forward list   forward_list<int> flist2 = {4 5 6};   // Using reverse() to reverse 1st forward list   flist1.reverse();   // Displaying reversed forward list   cout << 'The contents of forward list after'  ' reversing are : ';   for (int &x : flist1)   cout << x << ' ';   cout << endl << endl;   // Displaying forward list before swapping   cout << 'The contents of 1st forward list '  'before swapping are : ';   for (int &x : flist1)   cout << x << ' ';   cout << endl;   cout << 'The contents of 2nd forward list '  'before swapping are : ';   for (int &x : flist2)   cout << x << ' ';   cout << endl;   // Use of swap() to swap the list   flist1.swap(flist2);   // Displaying forward list after swapping   cout << 'The contents of 1st forward list '  'after swapping are : ';   for (int &x : flist1)   cout << x << ' ';   cout << endl;   cout << 'The contents of 2nd forward list '  'after swapping are : ';   for (int &x : flist2)   cout << x << ' ';   cout << endl;   return 0;  }

Izlaz:

The contents of forward list after reversing are : 3 2 1 The contents of 1st forward list before swapping are : 3 2 1 The contents of 2nd forward list before swapping are : 4 5 6 The contents of 1st forward list after swapping are : 4 5 6 The contents of 2nd forward list after swapping are : 3 2 1

7. jasan() :- Ova funkcija uklanja sadržaj popisa naprijed. Nakon ove funkcije popis naprijed postaje prazan.

8. prazan() :- Ova funkcija vraća istinito ako je popis prazan inače lažan.

Izlaz:

The contents of forward list are : 1 2 3 The contents of forward list after clearing are : Forward list is empty
