LR_strcat and LR_strcpy

上一篇 / 下一篇  2007-09-03 16:24:50 / 个人分类:LR_String Functions

一、strcat

Concatenates two strings.

char *strcat ( char *to, const char *from );

to
The string at the end of which the from string is concatenated.
from
The string concatenated to the end of the to string.

strcat concatenates two strings.

二、strcpy

Copies one string to another.

char *strcpy ( char *dest, const char *source );

dest
The destination string into which source is copied. (目的)
source
The string that is copied. (源)

strcpy copies one string to another.

注意:

 
注意将字符串或者字符串常量放在一个字符变量中,而且字符变量需要设置长度,如果不设置会出错。如下:
Action.c(16): Error: C interpreter run time error: Action.c (16):  Error -- memory violation : Exception ACCESS_VIOLATION received.
Action.c(16): Notify: CCI trace: Action.c(16): strcat(0, 0x00e3023e "aaa")
.
Action.c(16): Notify: CCI trace: Compiled_code(0): Action()
.
 
Action()
{
 char *a="aaa";
 char *b="bbb";
 char c[1024];
    
char fullpath[1024], *filename = "logfile.txt";
 
     strcpy(fullpath, "把它考到fullpath中");
     strcat(fullpath, "【这个字符连接到fullpath后面】");
     strcat(fullpath, filename);
 
     lr_output_message("Full path of file is %s", fullpath);
 

    strcat(c,a);
 strcat(c,b);
 strcat(c,a);
 lr_output_message("%s",a);
 lr_output_message("%s",b);
 lr_output_message("%s",c);
     return 0;
}
