这么麻烦？举个例子来看嘛。
你看replicate('0',5)="00000"
就这么简单

Header File
string.h
Category
Manipulation Routines
Syntax
#include <string.h>
char *strnset(char *s, int ch, size_t n);
wchar_t *_wcsnset(wchar_t *s, wchar_t ch, size_t n);
#include <mbstring.h>
unsigned char *_mbsnset(unsigned char *s, unsigned int ch, size_t n);
Description
Sets a specified number of characters in a string to a given character.
strnset copies the character ch into the first n bytes of the string s. If n > strlen(s), then strlen(s) replaces n. It stops when n characters have been set, or when a null character is found.
Return Value
Each of these functions return s.

表达不准确，应该是：“将一个字符重复n次得到另一个字符串的函数”
就像sql server 里的replicate函数

“將一個字符重復n次”？？？
什么叫将一个字符重复n次？是不是 memset ？

表達不准確，應該是“將一個字符重復n次得到另一個字符串的函數“
如同SQL Server里的replicate函數
