I was searching on the web about a c++ function that can compare two strings and returns 1 if the data in both the strings are equal else 0. But I didn't get a satisfactory answer.
For example, consider the following pseudo-code,
a = "hii"
b = "bye"
The return value should be 0.
If,
a = "hii"
b = "hii"
The return value should be 1.
Do we have any inbuilt(or from STL) function which can do the job?
if a and b are std::string you could use a.operator==(b) a == b

Ofcourse you are using std::string so you will use std::string::compare.
if the value is zero, then they are equal otherwise they aren’t.

or you can just use the == operator

Or the <=> operator :)

Is there some way to reduce duplicated methods if I want to be able to return both cons and non-const references to some data from a class.
class Foo {
private:
SomeData a;
OtherData b;
ThirdData c;
public:
SomeData& getA();
const SomeData& getA() const;
OtherData& getB();
const OtherData& getB() const;
ThirdData& getC();
const ThirdData& getC() const;
};
Pavel
I have a lot of methods that return references and got a couple of places when it would be nice to have it const. and now I need to add a lot of boilerplate to some of my classes to support it

Define a function isVowel(char c) that returns true if a character entered is a vowel ('a', 'e', 'i', 'o', or 'u'), and false otherwise. You can assume that char is a single letter of any case (ie, 'A' and 'a' are both valid vowel).
Hint: You may require to include <stdbool.h>

>'Y' is considered a vowel when a word has no other vowel, it's used at the end of a word or syllable, or is in the middle of a syllable.

Then it'd be a vowel, no?

You don't really need to worry about 'Y' though since you're only getting a char

Good example! Splitting words into sylables is a difficult problem...

It really is, it'd probably require a reasonably complicated regex

The system used in TeX is the best known for English and some other languages (Chinese is difficult just to get distinct WORDS). The TeX system is described in a famout PhD thesis and made the "Trie" data structure famous.

My man just compare the given char against the valid scenarios and if it lands any it's true, otherwise false, don't concern yourself with 'Y' or syllables

can any one help me with a program that extracts and prints the second digit of an input data of
type int in c++
Danny
i have done this
Danny
#include <iostream>
using namespace std;
int main()
{
unsigned int given;
int second_value;
cout << "ENTER THE VALUE= ";
cin >> given;
second_value = given % 100;
cout << "VALUE= " << given << endl;
cout << "SECOND DIGIT= " << second_value << endl;
return 0;
}

cout << "VALUE= " << given << endl;
cout << "SECOND DIGIT= " << second_value << endl;
return 0;
}
given /= 10;
second_digit = given % 10;

let me try
Danny
ENTER THE VALUE= 234
VALUE= 234
SECOND DIGIT= 23

that was the output but wat if i used the for command

use double.

It's that mantissa has 24 bits only? And the biggest integer value without "gaps" in between is 16 mil?
robherc
given /= 10;
second_digit = given % 10;
That only works for a 3-digit number.
ex:
25 / 10 = 2
2 % 10 = 2
(wrong answer, should have been 5)
1394 / 10 = 139
139 % 10 = 9
(wrong answer, should have been 3)

cause I thought second digit from the right

#include <iostream>

second_value = given % 100;
cout << "VALUE= " << given << endl;
cout << "SECOND DIGIT= " << second_value << endl;
return 0;
}
If you convert your int to a string, it's easy to pull the second character from a string 😉

ok, that makes your code make a lot more sense, at least.

#1 You need to give us more specific information on where EXACTLY you are having a problem. We will noy write a whole program "from scratch" for you.
#2 Please show us what you have attempted already. If you don't prove to us that you're willing to try yourself, where is the value in educating an unmotivated student?
#3 What exactly is a "ksh"???

A float or int which is more advisable to use in your code?

Hi everyone,
Can anyone write a c++ program can tell how many even,odd, positive and negative number from the input .
Like ....
I input : -5 0 -3 -4 12
The output : even 3 , odd 2 , pos 1 , neg 3
...> Even : 0 , -4 , 12 ...etc

cout << sizeof(x) << endl;
cout << sizeof(y) << endl;

The output:

Displaying the values of variables:

Displaying the size of variables:

The size is the same.
So why do someone represent the value using decimal vs hexadecimal vs octal vs binary literal?
