After completing Exercise 8.1.1, test it by experimenting with different limitations for the str string. It helps if you replace the number 600 with the sym- bolic constant STRMAX, putting the following #define directive at the beginning of the program. During preprocessing, this directive causes the compiler to replace occurrences of STRMAX in the source code with the indicated text (600). #define STRMAX 600 You can then use STRMAX to declare the length of str char str[STRMAX]; and then use STRMAX to determine how many bytes to copy: strncpy(str, " My name is ", STRMAX); strncat(str, name, STRMAX - strlen(str)); The beauty of this approach is that if you need to change the maximum string size, you need to change only one line of code (the line containing the #define directive) and then recompile. c++
