Have difficulty to understand this pure C code to only print vowels twice from input string. Questions are commented at the end of each place.
The code was compiled without any problem, Q1: How does the logic work by repeating the same condition on both sides of "||" ? I tried using only one side of the OR condition, the code compiled without error but did not work as expected.
Q2:Even not quite sure how to ask this question. Is this a prototype of a function? But the calling is without any parameter see Q3.
Q3: Calling of the function does not have a parameter at all. How does it work?
Q4: I thought I understand this line, but I must have wrong catch because of Q2.
i have a function:
char *pcCityIdToCountryName(ADMIN_DB_DATA *pstHEader, unit uiCityID)
this returns a pointer to CountryName if cityId is given.
to retrieve countryname i give:
char *CountryName;
CountryName = pcCityIdToCountryName(..................);
but when i compile it is giving :... (5 Replies)
Dear All,
Here I want to know why we put =0 in case of pure virtual function, why not =1, =2 or any thing else
Please send me answer any one as soon as possible. (1 Reply)
Hello all
im trying to build function that will return void function pointer
what is mean is ( not working )

Hi.
Problem: I have to parse the payload of a packet. The payload could be in Big Endian Format (network byte order) or little. That depends on a flag present in the header of the packet.
Solution: A horrible solution could be to check for that flag everytime I have to read a field in the... (11 Replies)

if i create an array of pointers to a structure "struct node" as:

Hi,
In the below C code,
#include <stdio.h>
void print() {
printf("Hello\n");
}
int main() {
void (*f)() = (void (*)()) print;
f();
(*f)();
}
I wonder, how the syntaxes "f()" and "(*f)()" are treated as same without any error? Is this an improvement or ANSI/ISO... (1 Reply)
I'm trying to write a programme which scans strings to find how many vowels they contain. I get an error saying that I'm trying to compare a pointer and an integer inif(*v == scanme){. How can I overcome this ? Also, the programme seems to scan only the first word of a string e.g.: if I type "abc... (1 Reply)

thai/wtt.h -
WTT I/O implementation.
SYNOPSIS
Enumerations
enum WTTClass { CTRL = 0, NON = 1, CONS = 2, LV = 3, FV1 = 4, FV2 = 5, FV3 = 6, BV1 = 7, BV2 = 8, BD = 9, TONE = 10, AD1 = 11, AD2 = 12,
AD3 = 13, AV1 = 14, AV2 = 15, AV3 = 16 }
Classification of characters in TIS620 according to WTT.
enum WTTOp { CP = 1, XC = 2, AC = 3, RJ = 4, SR = 5 }
Composibility checking tables.
Functions
WTTClass TACchtype (thchar_t c)
WTT character class.
WTTOp TACio_op (thchar_t c1, thchar_t c2)
WTT I/O operation.
Detailed Description
WTT I/O implementation.
WTT stands for Wing Tuk Tee (in Thai, Runs everywhere). It was defined by TACTIS (Thai API Consortium/Thai Industrial Standard) in the
NECTEC Thai Software Standard Project (1989-1991), and later endorsed by Thai Industrial Standard Institute (TISI) as TIS 1566-2541 in
1998.
WTT classifies Thai chracter(TIS-620) into 17 types below.
ITYPE VALUE SHORT_DESCRIPTION
CTRL 0 control characters
NON 1 non composible characters
CONS 2 consonants
LV 3 leading vowels
FV1 4 following vowels 1
FV2 5 following vowels 2
FV3 6 following vowels 3
BV1 7 below vowels 1
BV2 8 below vowels 2
BD 9 below diacritics
TONE 10 tonemarks
AD1 11 above diacritics 1
AD2 12 above diacritics 2
AD3 13 above diacritics 3
AV1 14 above vowels 1
AV2 15 above vowels 2
AV3 16 above vowels 3
Functions in thctype.h do basic character classifications while wtt.h classifies a chracter in detail. Please refer to the reference.
TACio_op() checks how to compose two given chracters. The possiblities are Composible (CP), Non-display (XC), Accept (AC), Reject (RJ) and
Strict Reject (SR). The values of CP, XC, AC, RJ and SR are difined in wtt.h. And their meanings are:
o CP : second character is displayed in the same cell as the first, also implies an acceptance.
o XC : Do nothing.
o AC : Display second character in the next cell.
o RJ : Discard second character.
o SR : Reject second character only in strict mode.
