C strcpy Function: Purpose and Risks

The strcpy function is used to copy one string to another string. Specifically, it copies the contents of the source string to the destination string and adds a null character (‘ \0 ‘) at the end of the destination string to mark the end of the string. The strcpy function will overwrite the content of the destination string and does not check the length of the destination string, which can potentially lead to buffer overflow issues. To avoid this problem, you can use the strncpy function to specify the maximum number of characters to be copied.
