Happy with my recent breakthrough in understanding C integer divisions after weeks of struggle, I was minding my own business having fun writing integer arithmetic code. Life was good, when suddenly… zsh: segmentation fault (core dumped). That code wasn't messing with memory much so it was more likely to be a side effect of an arithmetic overflow or something. Using -fsanitize=undefined quickly id
Sorry for the provocative title, but I'm too emotional these days. This code: #include <stdio.h> #include <string.h> struct tmp { int x, y, z; }; int main() { struct tmp* m_result_original=NULL; struct tmp* m_result_my_version=NULL; // m_result_original=do_something_version_1(); // m_result_my_version=do_something_version_2(); if (memcmp(m_result_original, m_result_my_version, sizeof(struct tmp)!=
#include<stdio.h> int testFunc(int, int); int main() { printf("%d\n", testFunc(1, 2)); return 0; } int testFunc(int inp1, int inp2) { int res; res = inp1 + inp2; return res; }
