The strcpy function copies strSource, including the terminating null character, to the location that's specified by strDestination. The behavior of strcpy is undefined if the source and destination strings overlap.
Parameters strDestination Location of the destination string buffer numberOfElements Size of the destination string buffer. strSource Null-terminated source string buffer. Return Value Zero if successful; otherwise, an error. Error Conditions strDestination ...
strcpy(str1,str2)将串2复制到串1,包括结束符\0一起复制 strncpy(str1,str2,n)从串2严格复制不超过n个字节到串1.即当串2长度小于n时全复制串2,当串2长度大于等于n时,只复制n个字节,不会额外追加结束符\0 实例:include "stdio.h"include "string.h"main(){ char a[30],b[30]="...
