Based on the phrasing of your question, I’m guessing that you are unfamiliar with the concept of pointers. In C, pointer is a type that stores the memory address of another variable. The & operator retrieves the memory address of a variable. int i = 4; // < An integer variable equal to 4 int* … Read more
Doing this: celcius=(ferenheit-32)*(5.0/9.0); Does not mean that the value of celcius will always be (ferenheit-32)*(5.0/9.0), anytime that ferenheit changes. What is does mean is that it sets celcius to (ferenheit-32)*(5.0/9.0) at the time the statement is encountered. Since ferenheit doesn’t have value yet when this statement runs, the value of celcius is indeterminate. You need … Read more
i’ve found solution to my problem. here is the right code if it can be useful for someone: #include “pgm.h” #include <iterator> #include <algorithm> #include <fstream> #include <sstream> using namespace std; bool convert16to8bit(const std::string& inFilename, mat<uint8_t>& img, const std::string& outFilename){ mat<uint16_t> imgTemp; ifstream is(inFilename, ios::binary); if (!is) return false; string magic; is >> magic; if … Read more
To erase the part of a string, you have to find where is that part begins and ends. Finding somethig inside an std::string is very easy because the class have six buit-in methods for this (std::string::find_first_of, std::string::find_last_of, etc.). Here is a small example of how your problem can be solved: #include <iostream> #include <string> int … Read more
To set to lower all the words below some length, you can split the words, and depending on its length set it to lower case. In this example i split on a space ” “,if there’s a possibility of another separators this would get more complicated: string unidade = “DIREÇÃO DE ANÁLISE E GESTÃO DA … Read more
You don’t want DateTime.Now.Millisecond, you want the total milliseconds: private static readonly DateTime Epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc); var totalMilliseconds = DateTime.Now.ToUniversalTime().Subtract(Epoch).TotalMilliseconds 5 solved Trying to make a console application run at 20 frames per second [closed]
The loop for(int i=0; i<5,i++;) is wrong. The condition i<5,i++ means i++ because the left operand of the comma operator i<5 doesn’t have side effect and simply ignored. i++ is evaluated to the value before the increment. In this case the value is 0, so it is considered as false and the loop body won’t … Read more
You are not null-terminating the arrays you create. Try this instead: char* dynamicmem(char size) { char* temp = new char[size + 1]; temp[size] = ‘\0’; return temp; } char* regrow(char* ptr, int size, char c) { char *p = dynamicmem(size + 1); for (int i = 0; i < size; i++) { p[i] = ptr[i]; … Read more
As the comments stated, it’s not entirely clear where your problem is. It would be nice if you included an example for what you want to understand better, anyway, here’s an example: #include <iostream> void foo(int x) { std::cout << x << std::endl; } void foo(int* x) { std::cout << (*x + 1) << std::endl; … Read more
You need to learn how to debug your code. If you can’t do that with a debugger, write a function which prints to the screen the relevant information, such as the following: void paxDebug(const char *desc, ll arr[], ll sz, ll n, ll b, ll x, ll pos) { cout << desc << “\n”; cout … Read more

You can produce the expected output with #include <iostream> using namespace std; int main() { int week, day; cout << “Enter No. of days:”; cin >> day; week = (day – 1) / 7 + 1; day = (day – 1) % 7 + 1; cout <<“\nWeeks: “<<week<<“\nDays: “<<day << endl; } solved Program to … Read more
I have posted the same post in Nvidia CUDA forum: Link Here I reinstalled multiple times with the method from the post but still having the same “class template” problems. Then I reinstalled CUDA 9.1 and VS2017 ver 15.6.7 also with the same method and it finally works. Further problems that I encountered is in … Read more
int deci, rem, octal=0, i=1; float de, x,y,point,rem1; cout<<“enter the decimal”<<endl; cin>>deci; Since deci is declared as int cin>>deci and entering ‘12.5’ will set deci to 12 BTW I assume the next line is a transcription typo deci=y doesnt make any sense at all. I assume you mean y = deci Solution – declare deci … Read more
