问题 Hi I have a program that deals alot with vectors and indexes of the elements of these vectors, and I was wondering: is there a difference between uint and unsigned int which is better to use one of the above types or just use int as I read some people say compiler does handle int values more efficiently, but if I used int I will have to check always for negative idxs which is pain. do you think iterators to be better? is it more efficient than normal indexing vectorx[idx] ? p.s the software

问题 I am making a small game in the console that takes place over several days. The game starts by initializing the miners ore and money amounts as 0. When he mines, my function chooses a random integer between 20 and 71 that will then award him that amount in 'ore'. I am trying to assign the ore that has been mined to my player's ore amount. I am having a reoccurring error that states that += is an unsupported operand for method and int. Full code and trace is below. Code import pyautogui as pag

问题 Requirement : One particular column in a DataFrame is 'Mixed' Type. It can have values like "123456" or "ABC12345" . This dataframe is being written into an Excel using xlsxwriter . For values like "123456" , down the line Pandas converting it into 123456.0 ( Making it look like a float) We need to put it into xlsx as 123456 (i.e as +integer) in case value is FULLY numeric. Effort : Code Snippet shown below import pandas as pd import numpy as np import xlsxwriter import os import datetime

问题 In C++ there is a way to cast a char to int and get the ascii value in return. Is there such a way to do the same with a qchar? Since unicode supports so many characters and some of them are actually looking alike, it is sometimes hard to tell what one is dealing with. An explicit code point or a number that can be used to get such would be very helpful. I searched a the web and this site for a solution but so far no luck, Qt documentation isn't much of help either, unless I'm overlooking

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . Improve this question I want to know how to get the product of two integers using only the addition or subtraction operators and without using the division and multiplication. If you could add the while statement that would be helpful. A Basically, I want to know how to add a
