Some of the printfs are spelt with leading capital P and others with lower case. Some have a trailing a newline and some don't. The default behaviour of printf is to accumulate what you are supplying into a buffer across calls. (This makes it a lot more efficient if you are printing several short strings or even a character at a time.) The buffer is flushed if it fills up (buffer size is implementation dependent but usually a power of 2 somewhere between 512 and 8092). An additional rule is that if the output is determined to be a terminal in which case the buffer will also be flushed when a newline is seen. Consequently you wouldn't have seen the output from those lines lacking the trailing newline if they are executed until some other printf that does have a newline is printf'ed. (The whole stdio/printf thing is actually pretty hairy behind the scenes. Some fun functions you may not have known about are fflush, setbuf/setvbuf, freopen, fdopen and in glibc fopencookie!)
