Nej, ikke naar den er oprettet med new. Lav en ny new[] og kopier
elementerne hvis du vil bruge new (fx. fordi det er objekter du laver new
af)

Men, siden et er kun chars, du kunne jo overveje at bruge calloc, men
skjule det inden i en klasse, fx. Buffer:


// opretter fx en 128 bytes buffer per default
Buffer *b = new Buffer;

// detekterer af der er brug for mere plads og laver en realloc
b.add("256 bytes text here\n");

// laver en free
delete b;
