strncpy 字符串复制 原型:char * strncpy(char *dest, char *src, size_t n); 功能:将字符串src中最多n个字符复制到字符数组dest中(它并不像strcpy一样只有遇到NULL才停止复制,而是多了一个条件停止,就是说如果复制到第n个字符还未遇到NULL,也一样停止),返回指向dest的指针。 /* strncpy example */ #in...
char *strncpy(char *dest, const char *src, size_t n) 参数 dest -- 指向用于存储复制内容的目标数组。 src -- 要复制的字符串。 n -- 要从源中复制的字符数。 返回值 该函数返回最终复制的字符串。 例: #include <stdio.h> #include <string.h> int main() { char src[40]; char dest[12...
The strncpy() function returns a pointer to string1.Examples: strncpy() functionExample 1: Copy a specific number of characters from one string to anotherThis example shows how strncpy() can be used to copy a specific number of characters from one string to another. First, only 2 characters...
Example # 2: In the following example, we first initialized our char arrays named “a” and “b” to a fixed size of 6. After initialization, we passed our arrays to thestrncpyfunction with the length of the string to which it will be copied. ...
