#include <stdio.h> #include <stdlib.h> #include <string.h> int main () { char *str; /* Initial memory allocation */ str = (char *) malloc(15); strcpy(str, "codingdict"); printf("String = %s, Address = %u\n", str, str); /* Reallocating memory */ str = (char *) realloc(str, 25); strcat(str, ".com"); printf("String = %s, Address = %u\n", str, str); free(str); return(0); }
