Is the function strcpy always dangerous?

Question

Are functions like strcpy, gets, etc. always dangerous? What if I write a code like this:

int main(void)
{

char *str1 = \"abcdefghijklmnop\";
char *str2 = m         


        

Answer 1

yes, it is dangerous. After 5 years of maintenance, your code will look like this:

int main(void)
{

char *str1 = "abcdefghijklmnop";

{enough lines have been inserted here so as to not have str1 and str2 nice and close to each other on the screen}

char *str2 = malloc(100); 
strcpy(str2, str1);


}

at that point, someone will go and change str1 to

str1 = "THIS IS A REALLY LONG STRING WHICH WILL NOW OVERRUN ANY BUFFER BEING USED TO COPY IT INTO UNLESS PRECAUTIONS ARE TAKEN TO RANGE CHECK THE LIMITS OF THE STRING. AND FEW PEOPLE REMEMBER TO DO THAT WHEN BUGFIXING A PROBLEM IN A 5 YEAR OLD BUGGY PROGRAM"

and forget to look where str1 is used and then random errors will start happening...
