#includeIn this example, we first create a list called `numberList`. We then use the `push_back` function to add the numbers 1, 2, and 3 to the list. Finally, we use the `append` function to add the number 4 to the end of the list. We then use a for loop to iterate through the list and output each element to the console. This `idList Append` function is a part of the `list` package library in C++ programming.#include int main() { std::list
numberList; numberList.push_back(1); numberList.push_back(2); numberList.push_back(3); numberList.append(4); for(std::list ::iterator it = numberList.begin(); it != numberList.end(); it++) { std::cout << *it << std::endl; } return 0; }
