String Pointers
Q
What will be printed as the result of the operation below:
main() {
char *ptr = " Cisco Systems";
*ptr++; printf("%s\n",ptr);
ptr++;
printf("%s\n",ptr);
}
✍: FYIcenter
A
1) ptr++ increments the ptr address to point to the
next address.
In the prev example, ptr was pointing to the space in
the string before C, now it will point to C.
2)*ptr++ gets the value at ptr++, the ptr is
indirectly forwarded by one in this case.
3)(*ptr)++ actually increments the value in the ptr
location. If *ptr contains a space, then (*ptr)++ will
now contain an exclamation mark.
