Is there a way to replace a function within a method in c++

To fix this issue You can wrap your code within a function template taking a variadic parameter set, and forward that on the matching Fn callable parameter (I omitted some irrelevant stuff):
code :
#include <iostream>

template<typename Fn, typename ...Args>
void sort_tester(Fn sortfunc, Args... args) {
    int bigArray[] {1,2,3,4,5,6};
    bool flag = false;
    for (int i = 0; i < 6; i++) {
        int n = flag ? 1000 : 100;
        flag = !flag;

void selectionSort(int elem, int n) {
    std::cout << "selectionSort(" << elem << ',' << n << ")\n";
    // Do stuff ...

void mergeSort(int elem, int n, int extraParam) {
    std::cout << "mergeSort(" << elem << ',' << n << ',' << extraParam << ")\n";
    // Do stuff ...
int main() {

Cannot use replace method inside a function

I wish this helpful for you $('anything that is not on the page').val() is undefined, which does not have the replace method. To briefly circumvent this error for before the DOM is done loading your .project textarea, consider using $(document).ready, or swapping undefined with '' for that special case:
code :
var thisChars = (textarea.val() || '').replace(/(\r\n|\n|\r)/g, '').length;  // laziest solution
function displayLength() {
    if (textarea.val() === undefined) {
        return;  // do not run any further.
    var thisChars = textarea.val().replace(/(\r\n|\n|\r)/g, '').length; 
    if (thisChars > limit) {
        $counter.text(thisChars + ' of 200 chars');
        var CharsToDel = (thisChars-totalChars); 
        textarea.value = textarea.value.substring(0,textarea.value.length-CharsToDel);

    } else {
        $counter.text(initial + thisChars + ' of 200 chars');

fixed the issue. Will look into that further It's not clear what you want to test.
If for some reason you want have list-like "response" and it should act as response (i.e., have count method), you should create such object and set it as return value.
code :
class Response(list):
    def count(self):
        return len(self)
patched_collection.find.return_value.batch_size.return_value = Response([{'id': 1}, {'id': 2}])

Hope this helps The JS String Replace method can take a function as it's second parameter, which will get passed matches in the input string. Each match gets passed into that inner function, and is replaced in the input string by whatever that inner function returns.
In this case the pattern matches [A-Z] (all capital letters).

I wish did fix the issue. The issue with your current text replacement is that \ is considered an escape character- the literal characters \n are interpreted as a newline character instead. To solution to this is to escape the \ character itself, via \\. Your updated replace statement would then read:
code :
a = message.replace('\\n', '')
a = message.replace('\n', '')

I think the issue was by ths following , This is very confusing. If someone else reads it, they won't understand what is going on. Just put a if statement at the beginning of your method.
