![]() Sure enough the written program immediately crashes. Me: Can you show me CCF compiles the program. For this go to Settings->compiler s-> select global compiler settings default-> selected compiler GNU GCC compiler default Then below in compiler settings check 'Have g++follow the C++11 iso.' Click ok. Try typing A as input and see for yourself (once you correct the missing &). My code is fine, it wont make the executable correctly. Originally Answered: How do I use unorderedmap in Codeblocks12.11 Its a feature of C++11 and you need to enable this manually. If it does not return 1 in the case of a single conversion, the target variable was not modified and the offending input will stay in the input stream, causing the same behavior to repeat indefinitely. Note also that you should test the return value of scanf(). This is because windows cant find the OpenCV dlls we created when we compiled OpenCV (in simple terms dlls are libraries written by humans in C++, etc. ![]() Use gcc -Wall -Werror or clang -Weverything -Werror to get maximum help. CodeBlocks, OpenCV and MinGW are now all set up to work, but if you try to compile a program which includes OpenCV libraries, the program will compile but crash when you run it. Note that the compiler can warn you about this kind of silly mistake it you increase the warning level. You should write: scanf("%f", &scoreEntered) ![]() The warning at the beginning seems to be normal when running codeblocks on Arch and shouldnt cause the. , and your program used 2.8 (no debug,Unicode,compiler with C++ ABI 1010,wx containers,compatible with 2.6). ![]() Consequently, an uninitialized variable will have some value, but there is no way to predict what that value will actually be. Codeblocks crashes for me after one of the latest. ![]() Thank you Code::Blocks 17.6 Win32 / gcc version 3.4.5 (mingw-vista special r3) / Windows 7 ServicePack1. When posting this problem, include the name of your compiler, operating system, Code::Blocks version, compiler log (go to Settings->Compiler and debugger.->Build options (tab) and check Save build log and Always output the full command line), and, if it caused Code::Blocks to crash, the codeblocks.RPT file (located in the Code::Blocks. Memory allocated to a variable in C++ is not cleared or zeroed upon allocation. I think is a bug in MinGw compiler or compatibility with my windows system. The problem is you are passing scanf() the value of scoreEntered instead of its address. Uninitialized variables are one of the most devious mistakes commonly made in C++. ![]()
