Why does the following code crash under MSVC++ 2010, and give unexpected output under turbo c , if a space is not given between '%s' and '%c' in scanf....
Code:#include <stdio.h> int main() { char c,name1[15]; scanf("%s%c",name1,&c); printf("\n%s %c",name1,c); return 0; }

It's fine on MSVC 2010 when I try it. What are you giving as input? How do you mean "crash"?
program was crashing because I forgot an ampersand befor c in scanf, but the output is still weird.
Your problem is the behavior of scanf. %s reads up to the first whitespace, %c reads the whitespace, and last character goes unread. A space before a %c tells scanf to ignore all leading whitespace.
And without the space between the, scanf will keep reading stuff that matches %s and not put anything in c until you hit enter, then it'll put the newline in c (because the newline doesn't match %s but does match %c).
