c++ - Insert element and move elements after in vector -

I am writing a linked list using a vector (and I know that I should not use vector) I am trying to apply a task to insert a node to x and position all the elements after x , but some For reasons it basically takes the element present on x and all subsequent elements with this value The breakfast.

This is the function with which I am having problems:

  // X index Enter element on zero linkedlist: insertAt (int x, int data) {node * TempNode = new node (); Node * moves = evolution [x]; Node * ignore = evolution [x + 1]; Node * previous node = vikilist [x - 1]; If (x == count) {push_back (tempNode, data); Return; } And {count ++; (Int i = 0; i  Previous = previous node; TempNode-> Next = next node; TempNode-> Id = x + 1; VecList [x] = tempNode; VecList [x - 1] - & gt; Next = tempNode; // In the node, the node of the previous node adds the /} node, but instead of the organ node,  

this position holds the value passed in x I think my problem is with the transfer of elements after the x .

When I linked list .inertAt (2, 50); Calling on: 10, 20, 50, 30, 30 , but expected: 10, 20, 50, 30, 40 .

Definition of node

  Structure node {node * Previous; Node * next; Int id; Int data; };  

The problem is your loop:

 for  (Int i = 0; i & lt; getSize (); i ++) {vecList [x + 1] - & gt; Next = Evaluate [x] - & gt; next; // 'Temp- & gt; Next 'K' Temp 'vecList [x + 1] - & gt; Data = vecList [x] - & gt; Tranfer the data address; If (vecList [x] == NULL) {break;}}  

you are running again on i , but anything in the loop actually < Code> i . So you're just doing the same operation getSize () times I think you want vecList [i + 1] to veclist [i] Wanted to Also the lower bound of the loop should not be 0 , it should be x . For more clarity, the name of that variable should probably be pos or something like that.

Whenever you are referencing vecList [x + 1] or vecList [x - 1] . What if x is 0 or vecList.size () - 1 ? You will point to an undefined object.
