How can I add a char to string?

 

[Zyrenthian]

couple of options. if you have a buffer that can fit the new character

char buffer[128];
strcpy(buffer,"HELLO WORLD"


you could just do

char newCharacter = '!';
buffer[strlen(buffer)] = newCharacter;
buffer[strlen(buffer)] = 0; // REQUIRED

or you could do

char Hello[] = "hello world";

char buffer[128];
sprintf(buffer,"%s%c",Hello,'!');

Just a couple of ways... there are many.
