C++ :: Estimate Springtime Count Of Deer In A Park For 10 Consecutive Years
Dec 2, 2013
Write a C++ program to estimate the springtime count of deer in a park for 10 consecutive years. The population of any given year depends on the previous year's population according to the following calculation:
• If the lowest winter temperature was less than 0 degrees, the deer population drops by 15%.
• If the lowest winter temperature was between 0 degrees F and 25 degrees F (inclusive), the deer population drops by 10%.
• If the lowest winter temperature was between 26 degrees F and 30 degrees F (inclusive), the deer population doesn’t change.
• If the lowest winter temperature was between 31 degrees F and 35 degrees F (inclusive), the deer population rises by 12%.
• If the lowest winter temperature was higher than 35 degrees F, the deer population rises by 14%.
I have started with:
#include <iostream>
#include <stdlib.h>
#include <string>
using namespace std;
int main() {
int year;
int pop1;

Write a program that outputs inflation rates for two successive years and whether the inflation is increasing or decreasing. Ask the user to input the current price of an item and its price one year and two years ago.
To calculate the inflation rate for a year, Uh, no, that’s wrong! To calculate the inflation rate for a year, subtract the price of the item ONE YEAR AGO from the price of the item for that year and then divide the result by the price a year ago. For example: 2014-Inflation-Rate = (2014-Price minus 2013-Price) / 2013-Price.
Your program must contain at least the following functions:
•a function to get the input
•a function to calculate the results
•a function to output the results

4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.

Your objective is to write a program that calculates the simple interest for a given loan amount and duration (in years).
Formula:
Simple interest = loan amount X interest rate X number of years
Assume interest rate is a constant 6% per year.
Specifically, your program will:
1. Output descriptive header
2. Prompt and read any customer’s first name, middle initial, and last name individually
3. Prompt and read the principal/loan amount
4. Prompt and read the duration of the loan in years
5. Calculate the interest
6. Output:
a. Customer full name
b. Principal/loan amount
c. Duration of loan
d. Interest rate
e. Interest on loan
f. Principal and interest due at end of term
OK SO THIS IS MY PROGRAM SO FAR. As you can see i got it all but i am so confused with as to for loan amount and duration of year, if i should use float or double to declare it?
i need to finish this assignment by calculating the simple interest and i dont know how or where to begin.
int main(){
system("color f0");
string firstName;
string middleInitial;
string lastName;
cout<<"Please enter your First Name: ";

I have an array of groups of numbers (I call them classes), that might look like this:
Code: static const int arr[] = {1,1,3,3};
std::vector<int> classes( arr , arr + sizeof(arr) / sizeof( arr[ 0 ] ) );
or like this
Code: static const int arr[] = {1,3,3,3,5,5,6,8};
std::vector<int> classes( arr , arr + sizeof(arr) / sizeof( arr[ 0 ] ) );
The groups of numbers are in an increasing order, but not numbered consecutively. So, would I would like to have is this
1,1,2,2
and
1,2,2,2,3,3,4,5
A loop like this
Code: for ( int i = 1; i < classes.size(); i++ )
if ( classes.at( i ) > classes.at( i - 1 ) )
classes.at( i ) = classes.at( i - 1 ) + 1;
does not work, because it changes the preceding value in the group, thus destroying the group. How would you do it?

So I have a text file named test.txt on the root of my c:/drive.
I finally managed to arrays working and reading into them, but when I started looking at the data in the array I noticed that stringstream was not "grabbing" a specified space. LINES 83-88
The text file contains the following (note that there is an intentional space after the first word):
I ' m s o r 0 y 4 D a v e , 5 12 12 12 3 7 f 11 2 i d 5 8 1 c 5 n 10 t 5 7 17 2 3 h 7 2 .
I need that space to be caught in the steam, there will always be only one space after a various first word, but I need it in my array and stringstream doesn't catch it.
if you need to run it, just copy the text to a file named c:/test.txt
When you run the code, you will see after the 3rd iteration it skips the space, is there a way to change this, so I can focus on the decryption algorithm??

Code:
#include<stdio.h>
#include<string.h>
typedef struct test
{
char a[5];
char b[10];
}t;
[Code] ....
In Unix (HP-UX) and Linux, the output of above program will be:
t.a=Helloworld!
Instead of the value of t.a ,i.e, "Hello" only.
Why such output? And what is the trick here to print the only value of t.a.

I am trying to overlay an image on a live video.I have used alpha blending method to overlay image on the video. On overlaying the image, it gets overlayed five times rather than one as expected.
Both frame data and the image data is taken as BYTE* for overlaying and displaying it.
The image used is a bitmap image.
The data (BYTE*) of both the video and the image is overlayed and the resultant is stored back in the variable of the video and den drawn on the picture control of vc++.
The video resolution is 640x480.
The image I m overlaying is 128x128.
The IDE used is visual studio professional.The code is developed using c++.
How do I overlay the bitmap image as a single image on the live video at a specific position.

Develop a function that finds the greatest difference between two consecutive elements stored in an array. Develop a 9 element array of doubles to test your code. Print to the screen which two numbers have the greatest difference as well as the value of the difference. Finally include an overloaded version of the function that will work if the array is composed of integers. Include your code used to test this function.

I'm just trying to find out if the way I've setup my code currently allows me to count the letters as they occur? I don't yet see how to do it but I need clarification. Ideally the function letterCounter would do the counting but atm I'm just trying to figuring it out in the display function.

I have the following code to print a string to the LCD using my PIC32 Starter Kit; I have made this code work with success. I cannot, however, make the LCD print numbers.
#include<p32xxxx.h>
#define LCD_PRT PORTE //LCD DATA PORT
//#define LCD_DDR DDRE//LCD DDR
//#define LCD_PIN PINE//LCD PIN

I want to change the original code as little as possible, don't worry about my header files - they are fine.

i couldn't count the 2d string. my string is list[100][100] = {"Batuhan","Jeyhun","Tashtanbek"} this is a food line in cafeteria. i want to add a person to this list but i couldnt do it because i dont know the length of my list. it will be more than 3 after i add a person but what if i would add another person after that ? In that case i couldnt be able to tell how long is my line.And after i add people to my list i want to print that list. here is where i came so far:
case 1:
printf("Enter the name of the person to be added
");
printf(">>");

I am using this code that to check a set of values from a text file and show it on the output.
Code: void MatchNumber(int b) {
vector<Rect> rects;
ifstream theFile("CheckNumber.txt");
double x1,y1,x2,y2;
while(theFile >> x1 >> y1 >> x2 >> y2 ){
rects.push_back(Rect(x1,y1, x2,y2));
}
int num=0;

I want to calculate how many times the common number is repeated . So I have used freq[num] in that function. But I am getting the output like this-
Code:
The common number is = 5
The 5 repeated = 1 times
The common number is = 6
The 6 repeated = 1 times
The common number is = 4
The 4 repeated = 1 times
The common number is = 5
The 5 repeated = 1 times
[code]....
So the freq[num] is only returning 1 instead of counting the total number of repeating which is wrong!! I would like to have somthing like this in my output -
Code:
The common number is = 5
The common number is = 6
The common number is = 4
The common number is = 5
The common number is = 5
The common number is = 8
The common number is = 9
The common number is = 6
The common number is = 6
[code]....
How can I do that?

I am new to c++. I am writing a program that reads in a text file and gives a count of how many times each letter appeared in the file. I got it to read the text file and do the letter count. B
X = 102
Y = 126
Z = 165
etc...
THAT IS WORNG
The sample output should be
E = 165
T = 126
A = 102
O = 93
etc...
I got it to sort from lowest to highest for the frequency, but cant seem to get the appropriate letter assigned to it.

I have loaded and 1d array from a .dat file, calculated the average of all the numbers. Now I need to count every number in the array that is below the average and cout that number. This is the method in the class I have so far:
int IntegerArray::countBelowAverage(int numBelowAvg) {
avg=IntegerArray::getAvg();
for(int ct=0; ct<avg; ++ct) {
numBelowAvg=ct;
}
return numBelowAvg;
}
My output from this is always 0 and I know that there are numbers below the avg.

I am trying to keep a count on a variable name stored within a structure as char*'s. They are of the same field and I do not know how many there will be so I would like to keep a standard name and append the count.
So say I have a variable name such as "desk", but as I have many of these said desks so I would like to call them "desk1", "desk2", "desk3" and so forth. Any recommendations on how I could do this?
Also since this is somewhat relevant is there an easy way to convert from an integer to a string, something that would work like atoi() in reverse? I wouldn't mind writing a method to do so myself but haven't a clue as to how.

I need a way to count lines in a .dat file using fscanf. I must use a regex to check that the characters in the file are alphanumeric. In essence I need to count the ' ' character. I know fscanf ignores this character. I need to exit if it detects anything other than alphanumeric with the digit that is "problem" along with the line number. My .dat file is:
Code:
howard jim dave
joe
(
Maggie My fileCheck.c is: Code: #include "main.h"
int fileCheck(FILE *fp)
{
int ret_val;
int line_count = 0;
char file[BUFF];
[Code]...
The output I am getting is:
Code:
file opened Digit: ( is not an alphanumeric character on line: 5 Program will exit! File closed As you can see, the character "(" is not on the 5th line but the 3rd. It is the 5th "string."
I also wanted to show the regex I am using.
Code:
#define to_find "^[a-zA-Z0-9]+$"
How this can be accomplished?
