Why do we think strncpy in C/C++ is unsafe?
Article Introduction:The function strncpy() is used to copy a specified number of characters from the source to the destination. The following is the syntax of strncpy() char*strncpy(char*destination,char*source,size_tn); here, destination is a pointer to the destination array into which the source string will be copied, and source is the character to be copied String, n is the maximum number of characters to copy from the source string.

Function of strncpy in c language
Article Introduction:The strncpy function is used in C language to copy one string (source string) into another string (destination string), up to a specified number of characters. Its prototype is char strncpy(char dest, const char *src, size_t n), where dest is the destination string address, src is the source string address, and n is the maximum number of characters to be copied. This function copies the first n characters of the source string. If the length of the source string is insufficient, null characters are used to fill the remaining space of the target string. If the length of the source string is greater than n, only the first n characters are copied without adding null characters. .
