strcpy and strcat cause problems sometimes

Question

hello I have a code like the one below

char *str ;

        strcpy(str, \"\\t<\");
        strcat(str, time);
        strcat(str, \">[\");
        strcat(s         


        

Answer 1

This is much simpler and error-free from buffer overflows:

#define BUFFERSIZE 512
char str[BUFFERSIZE];

snprintf(str, BUFFERSIZE, "\t<%s>[%s](%s) $ ", time, user, baseName);
