\n (Line Feed) → moves the cursor down to the next line without returning to the beginning of the line — In a *nix environment \n moves to the beginning of the line. \r\n (End Of Line) → a combination of \r and \n

Since n is, by definition, greater than n -1 or n-2, shouldn't any n^n, which is the product of n number of n's, be greater than n!, which is the product of an n number of integers less than n? exponential-function

2011年2月15日 · I assume that you want to prove that the function n! is an element of the set O(n^n). This can be proven quite easily: Definition: A function f(n) is element of the set O(g(n)) if there exists a c>0 such that there exists a m such that for all k>m we have that f(k)<=c*g(k). So, we have to compare n! against n^n. Let's write them one under ...

2016年1月6日 · in Unix and all Unix-like systems, \n is the code for end-of-line, \r means nothing special; as a consequence, in C and most languages that somehow copy it (even remotely), \n is the standard escape sequence for end of line (translated to/from OS-specific sequences as needed) in old Mac systems (pre-OS X), \r was the code for end-of-line instead

2021年8月29日 · Those who want to use %n Format Specifier may want to look at this: Do Not Use the "%n" Format String Specifier. In C, use of the "%n" format specification in printf() and sprintf() type functions can change memory values. Inappropriate design/implementation of these formats can lead to a vulnerability generated by changes in memory content.

2016年9月11日 · ^\n: the scanset is all characters except \n. Furthermore fscanf (and scanf) will read the longest sequence of input characters matching the format. So scanf("%[^\n]", s); will read all characters until you reach \n (or EOF) and put them in s. It is a common idiom to read a whole line in C. See also §7.21.6.2 The fscanf function.
