What does const pointer mean???

[JLBorges]

No, it is not the same in C. In C, the type of a (narrow) string literal is 'array of N char' (there is no const qualification).

Nevertheless, even in C, "if a program attempts to modify the static array formed by a string literal, the behaviour is undefined."

I saw a comment that change to const was proposed for C standard, but rejected. They apparently prefer the "undefined behaviour" version.
