Advertisements I would like to edit numbers in p2 according to the code in for cycle. But If I try to write out actual number in p2, I don´t see anything in output. What could I change to see it? #include <iostream> using namespace std; int main() { int p1[10]={-5,-8,0,5,0,-8,-11,-2,1,-7}; int p2[10]={0,0,0,0,0,0,0,0,0,0}; for(int i; i… Read More Why I can not see output in cycle (C++ simple code)?
Advertisements the code is OK and works I think but I don’t get the result that I’m looking for ` #include <iostream> using namespace std; int main() { int sum; int x; sum =0; x=1; while(x<=100) sum = sum+x ; x = x+1 ; } ` so if I add a cout inside the int… Read More where can i have a "cout" to get an output
Advertisements Hi I am using a C++ script as follows EX: int main(){ int x =7; std::cout<<"print num:"<<x<<std::endl; if(x>0){ std::cout<<" good"<<std::endl; return 5; } return 0; } For this in my python file I am calling the subprocess as follows: result0_1 = subprocess.check_output(MYCPP_fILE_PATH,shell =True) print(result0_1.decode("utf-8")) It prints out "print num:" and "good" but dosn’t provide… Read More How to get return value of c++ int main() output using subprocess.check_output() in python script
Advertisements I have a simple C++ test code. The way it should work is for a user to enter a sequence of integers through cin, followed by some character to terminate the cin input, then the code should output the integers. Next, the user should enter an integer other than zero to input another sequence.… Read More Why is cin apparently skipping input in this C++ code?
Advertisements #include<iostream> using namespace std; #define C 1<<(8*1) int main(){ if(C==256){ int a=C; cout<<a; } } My expectation is 256 but it print 18. What’s wrong with it? Thanks! >Solution : I assume your question is about std::cout << C;, not about std::cout << a;. Macros are simple copy-and-paste text replacement.

Advertisements I am trying to set up a class that initializes with a 2d array of an unknown size at compile time. I figured the best way to do this would be to pass the array as a pointer. This works as expected with a 1d array, but when I try to do the same… Read More Passing 2D array as class parameter
Advertisements This question is most likely common and has been asked before. So, after spending a mind-numbing 30 minutes trying to find the solution to what I believe is a false negative, I’m resulting to posting my issue here. I’m relatively new to C++ Coding and figured I’d create a simple random item generator. Unfortunately,… Read More Resolving potential false negative C6385 Error in C++
Advertisements Why does printf output characters instead of data? Looking at the code, you can relatively understand what I want to do, but it is unclear why the output is like this #include <vector> #include <string> #include <cstdio> class Person { public: Person(const std::string& name, uint16_t old) : m_Name(name) , m_Old(old) { } public: std::string… Read More Why does printf output characters instead of data?
