Why do the square of input decreases by one when using pow function? [duplicate]
问题 This question already has answers here : unusual output from pow (3 answers) pow() function in C problems [duplicate] (1 answer) Why the result of pow(10,2) 99 instead of 100? [duplicate] (1 answer) What's wrong with long? Why is subtracting 1 automatically? (1 answer) Closed last month . Here is a simple C program, which accepts a number from the user and results it's square. #include <stdio.h> #include <math.h> int main() { int number; int result; printf("\nEnter the number\n"); scanf("%d",
Error-flood when compiling simple hello world program
问题 I'm trying to compile a simple hello world program: main.cpp #include <iostream> #include <test/t.hpp> int main( int argc , char** args ) { std::cout << test() << std::endl; int x; std::cin >> x; return 0; } test/t.hpp #ifndef TEST_T_HPP_INCLUDED #define TEST_T_HPP_INCLUDED int test(); #endif // TEST_T_HPP_INCLUDED test/t.cpp #include <test/t.hpp> int test() { return 42; } With this makefile: executable_name = testapp cpp_compiler = g++ cpp_compiler_flags += -std=c++14 cpp_compiler_flags +=
Where Can I Get libgcc_s_dw2-1.dll?
问题 The programme I have written uses SFML but fails when run because libgcc_s_dw2-1.dll is missing. I'm using tdm-gcc and can't find the file anywhere on my computer and re-install doesn't help and a simple hello world programm works fine so I'm not sure why it needs this dll. Which mingw package can this be found in? I've had a search on the site but cant find it. Apologies if I have just missed an obvious search result but this is incredibly frustrating! Thanks in advance, ell. P.S. I'm on 64
C++ GCC4.4 warning: array subscript is above array bounds
问题 I recently upgraded to GCC 4.4 (MinGW TDM build) and now the follow code produces these warning: In member function 'void Console::print(const std::string&)': warning: array subscript is above array bounds Here's the code: void Console::print( const std::string& str ) { std::string newLine( str ); if( newLine.size() > MAX_LINE_LENGTH ) { sf::Uint32 stringSize = newLine.size(); for( sf::Uint32 insertPos = MAX_LINE_LENGTH; insertPos < stringSize; insertPos += MAX_LINE_LENGTH ) { newLine.insert(
Differences between Mingw-w64 and TDM-GCC for a simple GDI project
问题 I need to build a simple non-commercial tool (dealing with Windows GDI API) on Win64 for Win64 (no cross compilation). MinGW seems the best option for me. I have already used the 32 bit version in the past, as for 64-bit, can you tell me the main differences between the following builds?: Mingw-w64 TDM-GCC Besides the classic MinGW32 used a straightforward tool, mingw-get.exe , to customise the setup and keep up with the updating cycle. Which is the equivalent now? 回答1: I've posted a short

GCC's assembly output of an empty program on x86, win32
问题 I write empty programs to annoy the hell out of stackoverflow coders, NOT. I am just exploring the gnu toolchain. Now the following might be too deep for me, but to continuie the empty program saga I have started to examine the output of the C compiler, the stuff GNU as consumes. gcc version 4.4.0 (TDM-1 mingw32) test.c: int main() { return 0; } gcc -S test.c .file "test.c" .def ___main; .scl 2; .type 32; .endef .text .globl _main .def _main; .scl 2; .type 32; .endef _main: pushl %ebp movl
TDM-GCC w64 script to change windres for 32bit?
Trying to get the TDM-GCC(4.7.1) running on XP SP3 - I just need a c++ 32bit build for now.
