I am storing info in a vector but I want to store certain info at a particular index. I am new to using vectors and am unsure about have to do this. I am aware of the insert method but am confused on how to use it to store at a particular index.
View 1 Replies View RelatedI think std::copy appears to do what I'm looking for.
I'm in need of a vector member function that would allow me to "insert" a number of elements from one vector into another vector without resizing or destroying either.
An example of what I'm wanting to do is assign the contents of two[3-5][50-54] to one[7-9][2-6]. Other than looping through both vectors using .at(), is there a way to copy this?
This would be continuous within a user controlled loop with differing elements being exchanged.
typedef vector<vector<unsigned char> > vec;
vec one(10, vector<unsigned char>(10, '1')),
two(90, vector<unsigned char>(90, '2'));
Does it use Linked List or Dynamic Array?
I want to know this because if I happen to want to use a lot of insertions and deletions then it is more efficient to make use of Linked List instead of Dynamic Array.
While, if I happen to want to just access random parts of the Array, then Dynamic would be more efficient.
I want to make a 2D game using SDL engine and I need to check whether or not an object is colliding with a list of other objects. (because there would be more then one objects on the map.)
Since I would simply be accessing each object sequentially to check whether or not the object is colliding with another the object in question, and since any of those objects could "die" and be deleted at any time, it makes more sense to use Linked List then a Dynamic Array.
I have a nested record structure in C++ that contains a FileHeader record, a RecordHeader record and a DataRecord record. The last item is an array of unknown size (at compile time). I have to open a file and read the array size and then create the array.
I have worked on this for some time and can't figure out how to make it work. I know the sample data I am using has 85 records. I insert 85 into the array size and it works fine. But how do I create a dynamic array or define a vector within a nested structure?
1. What is the best (easiest) method to accomplish this (array or vector)?
2. How would it be implemented/how do you add data to it?
PreviousLogRecord.FaultRecord.push_back(field1); // does not work
PreviousLogRecord.FaultRecord[recordNumber].field1 = somedata; // works with 85 in array size.
struct LogFileHeaderRecordType {
QString field1;
int field2;

This creates quite a mess. It seems that somehow the "vector" declaration isn't working as the referenced web link seems to suggest that it should. I presume that, as usual, clearing one real error will eliminate the cascade of errors the first real error produces. Why won't VC++ accept the "vector" identifier?

By the way, how to implement "insert" and "heapify" and in insert, when we insert an element we also heapify it?
My program will ask the user to enter the number of lines for the sentence "I will always use object Oriented programming. " if for example, the user enters 3, it should print out
I will always use object Oriented programming. I will always use object Oriented programming. I will always use object Oriented programming.
the second part of my program asks the user to enter the line which we want to make a typo. If they enter 2, it will replace the "I will always use object Oriented programming. " with "I will always use object Oriented programing." in the second line.
this is how it should look like but I am having trouble putting the second part together. I don't know how to remove the sentence and replace it with the second part.
Enter the number of lines for the punishment: 6
Enter the line for which we want to make a typo: 3

Make a C++ Program that will use nested if else and any looping statement to display the following a certain number of times depending on how many times the user wants it to do so.
Input Values:
1. Name of employee
2. Position in the company
3. No. of hours worked
4. Rate per hour
5. Overtime hours
Required Output:
No. Name Position Rate per No. of hours Basic No. of overtime Overtime
hour worked Pay hours Pay
1. Juan Manager 160 140 22400 10 2100
Computations:
basic pay = no. hours worked x rate per hour
overtime = overtime hours x 150% of rate per hour
Just asking how can I input the name, position, rate per hour, overtime hours and hours worked in a horizontal manner?
Because I need to achieve the required output.
