Pseudo is
-> integer type count =0;
->Take input from user 'Number'
->loop from 0th to 24th element
->Compare each element with user entered number and if it matches then do count++.
finally display the count.

Write a program that accept a number and output its equivalent in words.


Below is the program written in Turbo C.

#include<stdio.h>
void pw(long,char[]);
char *one[]={" "," one"," two"," three"," four"," five"," six"," seven","
eight"," Nine"," ten"," eleven"," twelve"," thirteen"," fourteen","
fifteen"," sixteen"," seventeen"," eighteen"," nineteen"};
char *ten[]={" "," "," twenty"," thirty"," forty"," fifty"," sixty","
seventy"," eighty"," ninety"};

void main()
{
long n;
clrscr();
printf("
Enter any 9 digit no: ");
scanf("%9ld",&n);
if(n<=0)
printf("Enter numbers greater than 0");
else
{
pw((n/10000000),"crore");
pw(((n/100000)%100),"lakh");
pw(((n/1000)%100),"thousand");
pw(((n/100)%10),"hundred");
pw((n%100)," ");
}
getch();
}

void pw(long n,char ch[])
{
(n>19)?printf("%s %s ",ten[n/10],one[n%10]):printf("%s ",one[n]);
if(n)printf("%s ",ch);
}

HOW TO COUNT THE OCCURRENCES OF A TEXT STRING


In the cell that you want the result to appear in, enter the appropriate formula from the following examples.
How to Count the Occurrences of a Number
Use this formula
=SUM(IF(range=number,1,0))
where range is the range that you want to search, and number is the number that you want to count.
NOTE: This formula must be entered as an array formula. To enter an array formula, press CTRL+SHIFT+ENTER.
How to Count the Occurrences of a Text String
Method 1
Use this formula
=SUM(IF(range="text",1,0))
where range is the range that you want to search, and text is the text that you want to find (the text must be enclosed in quotation marks).
NOTE: The above formula must be entered as an array formula. To enter an array formula, press CTRL+SHIFT+ENTER.
Method 2
Use the COUNTIF() function to count the occurrences of a text string. For example, use the formula
=COUNTIF(range,"text")
where range is the range of cells that you are evaluating, and text is the text string that you want to count instances of (note that text must be enclosed in quotation marks).
NOTE: This formula must be entered as an array formula. To enter an array formula, press CTRL+SHIFT+ENTER.
Wildcard characters can be used within the COUNTIF function.
The asterisk character (*) represents more than one character. For example, to count all the cells in the range a1:a10 that contain an "x," you can use the following formula:
=COUNTIF(a1:a10,"*x*")
The question mark character (?) can also be used to represent one wildcard character -- for example, to count all cells in the range whose second character is the letter, such as "ax" or "bx."
=COUNTIF(a1:a10,"?x*")

Hwo can i solved a bineary search problam in c++


first arrange your array in ascending order.and keep the two variables one for starting index and one for last index
then check your number with center(center = (first index + last index))/2 element of array.
if it is lager then center element then set first index = center,
if smaller then last index = center
else you got the number..

Hi.

I suggest creating an Array of Cards (cardOne,cardTwo,etc. to five)

If you can enter them in one at a time, after declaring the array, assign the values to the array.

cin < cardOne; (Psuedo code by the way, hope you don't mind)

Afterwards, you'll have an array with 5 cards.

Declare what full houses, flushes, etc would require.
Use an if statement (If you don't mind lots of code) to compare the entered Array against possible hands.

I didn't necessarily give you any specific C++ code. However, if you Google C++ user input, you should find plenty of commands that may help you.

Good Luck

(And not sure about Linear search to be honest, you can use a Linear search, but if you did it the way I explained, you just have to compare hand to a series of conditionals.)

Keyless entry on door 2003 ford f-150


this is from the Ford owners manual.
Programming a personal entry code
To create your own personal entry code:
1. Enter the factory set code.
2. Within five seconds press the 1 • 2 on the keypad.
3. Enter your personal 5-digit code. Each number must be entered
within five seconds of each other.
4. The doors will again lock then unlock to confirm that your personal
keycode has been programmed to the module.
Tips:
• Do not set a code that uses five of the same number.
• Do not use five numbers in sequential order.
• The factory set code will work even if you have set your own personal
code.
• If you set a second personal code it will erase your first personal code.
