Hi, I receive the following compile error. c:..Blah.cpp(52) : error C2440: 'initializing' : cannot convert from 'const char *const [64]' to 'char ** ' Conversion loses qualifiers < outside of main> enum { sz = 64}; const char* const names[sz] = { "Frodo", "Gollum", "Sam", "Treebeard", "King", "Garcia", "Burdine", "Eriksen", NULL }; <within main> <line 52> for (char** p = names; *p; p++) {;} I thought names was a pointer to an array of string literals, whose values could not be change, nor could the location where names pointed to be changed. With char** p, I'm trying to point to where names points to. Please explain where I've gone wrong.

Quote: { "Frodo", "Gollum", "Sam", "Treebeard", "King", "Garcia", "Burdine", "Eriksen", NULL }; within main line 52> for (char** p = names; *p; p++) If you need to iterate over the array of const char*, you have to declare your 'p' as const char**. Quote: {;} I thought names was a pointer to an array of string literals, whose values could not be change, nor could the location where names pointed to be changed. With char** p, I'm trying to point to where names points to. Please explain where I've gone wrong. One more thing you've done wrong is not posting the _entire_ code. Consider visiting the FAQ section 5 at some point in the future.
