The line World(height, width); constructs a temporary object and discards it. The member variable of the current object never get initialized properly. Simplify your code. Move the code to get input data to the function that calls it. For example, use it in main. int width = -1; int height = -1; cout << “Aby … Read more
There are many statements in your code that literally DO NOTHING, 7+8+14; a+a2; b+b2; c+c2; d+d2; e+e2; f+f2; and answer=answer; You see, answer is uninitialized. You never set it’s value in the code, so you need something like // Initialize `answer’ here answer = 7 + 8 + 14; answer = answer + a + … Read more
What you’re doing (reading the value of an uninitialised variable) is undefined behaviour; anything can happen, from it appearing to work, to printing random values, to crashing, to buying pizza with your credit card. 2 solved Why uninitialized variable print a strange negative value? [duplicate]
Add cout.flush() (or std::endl which implicitly flushes) after each cout statement. cout uses buffered output, using cout.flush() will clear the buffer and force the contents being written out. Thanks πάντα ῥεῖ for guidance solved cout not working in c++ after taking line input (getline)
initBoard doesn’t do anything. for(int y = 0; y < 0; y++) y starts at 0. 0 is not less than 0, so the loop does not run. Put the size of your board (8) in a constant, then use that everywhere, and you’ll be less likely to use the wrong number. 0 solved Why … Read more
Why should the compiler warn you about something that is perfectly legal? You are instructing the program to output the content of cout, which is legal, and will work. I am not sure how the operator << is defined for cout, but printing its address would be my expectation, so something like 0x489944 (or longer) … Read more
Basically it comes down to the fact that an iostream has quite a bit of state to store, but a string has very little. Nonetheless, the idea of a string having a size of only 4 is a little surprising (at least to me). I’d normally expect something like 12 for a 32-bit implementation, or … Read more
Got it, friend of mine has had the same issue. _setmode(_fileno(stdout), _O_TEXT); And cout go back to normal behavior. He’s telling me something about a sh***y VC++ compiler and openGL old version. (Init openGl world screwed stdout in some sort of way, if i understood) 0 solved Cout + Float, no debug error, crash on … Read more
The code presented by you in a C++ program. You need to save it in file.cpp format, after that you need to compile with g++ file.cpp and it should work. You have saved it file.c format and compiling it with gcc, which is C standard, not C++. solved can’t understand “std::cout”
