Erase() function to remove a range of elements from a vectorWe can also remove a range of elements by passing first and last position in the erase function. Syntax: For removing a range of elements: vector_name.erase(iterator first, iterator last);Example: vector1={10, 20, 30, 40, ...
It shifts the unique elements towards the beginning of the range and returns an iterator pointing to the end of the new unique range.auto last = std::unique(myVector.begin(), myVector.end()); With the sorted and unique elements identified, the duplicates can be erased from the vector ...
Usestd::eraseandstd::removeFunctions to Remove Element From an Array in C++ Another scenario for this problem occurs when the given array is of typestd::vector. This time, we have the dynamic array features, and it’s more flexible to use a built-in function for element manipulations. ...
In those scenarios how to handle exceptions without try catch?Well, just to make it clear... this kind of "exception"'s here are not the same kind of exceptions you know from other languages. As it has been said already, such exceptions are bugs. Access-violations or divisions by zero ...
myvector =name of the vector of vector So the outer vector can be thought of as a vector (1D) whose element is also a vector. Advantages for vector of vectors compared to 2D array, is that one can expand vector as much as he wants. Like, you have no restriction for size. For ex...
2. How to Initialize a Vector From an Array in C++: You can initialize a vector from an existing array. In the below example, I will show you how you can initialize the vector with an existing array. You need to create and initialize an array first; then copy all the elements of the...

Also, since the variable is still uninitialized, the compiler assigns a random garbage value to it. Example Program For Declaration Of Variables In C++ Language Below is an example C++ program where we declare a variable and then print its value without initialization. Code Example: #include <io...

elements. You can wrap elements in ashared_ptr, and then copy it into other containers with the understanding that the underlying memory is valid as long as you need it, and no longer. The following example shows how to use theremove_copy_ifalgorithm onshared_ptrinstances in a vector. ...
