pull requests great understanding larger thinking around change or set of changes made repo. reading pull requests great way "grok" project as, instead of small atomic changes source, larger groupings of logical changes. analogous organizing lines in code related "stanzas" make easier read. i find myself looking @ file or commit, , wonder if there way backtrack commit pull request created it. pull request have been merged eventually, not necessary merge-commit. you can go github , enter sha search bar, make sure select "issues" link on left. updated 13 july 2017 via github ui there easy way this. if looking @ commit in list of commits in branch in ui, click on link commit itself. if there pr commit , wasn't added directly branch, link pr listing pr number , branch went directly under commit message @ top of page. if have commit sha , nothing else , don't want go digging around it, add /commit/[commit sha] repo url, , see c...

can find wrong following code? int main(){ char *p="hai friends",*p1; p1=p; while(*p!='\0') ++*p++; printf("%s %s",p,p1); } i expected print space followed string! here way use ++*p++ : #include <stdio.h> #include <string.h> int main(int argc, char* argv[]) { char *p = "my test string", p1[15]; strncpy(p1, p, 14); p1[14] = 0; p = p1; while (*p != 0) { printf("%c", ++*p++); } } note p1 array of memory (usually) allocated on stack, whereas p (usually) pointer read memory, above code moves point p1 instead of (usually) read location string resides. operating systems and/or compilers exhibit other behavior, 1 of protection mechanisms built modern oss prevent classes of viruses.
