C++ :: Console App - Outfile Results
Aug 5, 2013
I have created a game that functions correctly, however, for balancing and future changes, I would like to record results .txt document (its 1v1 btw). I already have code to determine who won and what I am looking for is some way to keep track of different match-ups for the different characters. Im looking for something like this:
loser
Winner char1 char2 char3
char1 3 2 5
char2 2 5 4
char3 8 1 2
the numbers are the amounts of wins a given character has over another character. I'm looking for code to open the .txt file and add 1 to the respective win total so I can do balance changes and such.

I am trying to display my name using outfile vs. cout and I get errors I don't know how to fix. Here is the code:
//This program will calculate the monthly payment, the total amount paid back over the entire life of the loan,
// and the total interest paid over the life of the loan.
#include <iostream>
#include <fstream>
#include <iomanip>
using namespace std;
int main() {
ofstream outfile;
[code]....
And here are my errors:
1>z:csci207program1practice.cpp(13): error C2297: '<<' : illegal, right operand has type 'const char [16]'
1>z:csci207program1practice.cpp(13): warning C4552: '<<' : operator has no effect; expected operator with side-effect

How to get a txt Outfile to display a Checksum.
Code:
ChecksumFileDisplay = fopen(ChecksumFileDisplayPath, "r");
fprintf(ChecksumFileDisplay, BigEndianChecksum);
That's what I have but it doesn't like the fprintf function because BigEndianChecksum is an unsigned int and it wants a pointer to a const char. Is there a function similar to this that will display an 8 digit integer in a txt outfile?

How do I do the operation of two integers that gives you the results?
I'm supposed to write a program that:
Asks the user for an integer
Asks the user for one of '+', '-', '*', or '/' (as a character)
Asks the user for another integer
Performs the given operation on the two integers, and prints out the result of
Please enter an integer: 4
Please enter an operation (+, - , *, /): *
Please enter another integer: 5
4 * 5 = 20
Code:
#include <iostream>
using namespace std;
int main() {
int x;
int c;
int d;
char e;

I mean on the executable file. It just displays the results and quickly flashes away, cin.get() has no effect and system("PAUSE") is undeclared.
I never found a single sure way to pause effectively. Is there a method that works all the time? Sometimes cin.get() gets skipped even in the code itself. The IDE I am using is Code Blocks if that matters any.

I am using Excel 2013, Visual Studio 2015. I began learning about Excel XLL. I wrote simple function which tests whether the argument is missing. Here's code:
#define DllExport __declspec(dllexport)
static LPWSTR rgFuncs[1][7] = { { L"GetSum", L"BU", L"GetSum" } };
DllExport double WINAPI GetSum(LPXLOPER12 arg)
{
if (arg->xltype == xltypeMissing) return -1;
return arg->xltype;
}
This code works as expected: if I miss argument, it gives me -1, and the type otherwise. But when I change code to this:
DllExport double WINAPI GetSum(LPXLOPER12 arg)
{
return (arg->xltype == xltypeMissing) ? -1 : arg->xltype;
}
then, when I miss argument, it gives me 4294967295. Why?

The point of this program is to calculate how many cents the user would have after a certain number of days. The user is given .01 cent on day one, and this amount is doubled with each passing day. I cannot seem to figure out how to add all of the results. Currently, my program simply outputs them to the screen. How do I tell it to add all of the results and store the sum in one variable?
#include <iostream>
#include <cmath>
#include <iomanip>
int main() {
using namespace std;
float totalF = 0;//total amount earned after number of days specified by user have passed

I'm using below code snippet to fetch Youtube video titles, when you enter a query into a listbox, and press the search button:
int resultsn = 0;
void YTReq(string appname)
{
devkey = "my-dev-key-here";
YouTubeRequestSettings settings = new YouTubeRequestSettings(appname, devkey);
request = new YouTubeRequest(settings);
[code].....
But what i get is exactly 500 results, even if i remove the 500 search limit radio-button (i've put that later, after seeing that the search only fetches 500 results). But when i search the same query on YT, i get 1000s of results. What's the wrong with my code?

I am nearing completion of my first real app.. but I noticed a nasty catch in that it consumes 10-20% CPU at idle. I went around commenting features that I suspected may be causing it but it had 0 impact and my CPU usage at idle is still 10-20%.
The program has two threads, one of which is used very little and the second one consume needless CPU.. The only clues a profiler gives me is
MS.Internal.Text.TextInterface.Generics.NativeIUnkownWrapper<MS::Internal::Text::TextInterface::Native::IDWriteFont>...
But the process which takes up all the CPU seems to change every time I start the profiler. Sometimes it is WindowProc or ThreadingProc..
Can how I interpret this and make meaningful changes to how my code runs?

I was doing problem 10 on project euler Project Euler. The following code produces two different answers on different systems:
Code:
#define INPUT 2000000
Bool isPrime(const int number) {
int i, sqr = sqrt(n);
if(n%2==0) return 0;
for(i=3;i<=sqr; i+=2)

Compiled by: gcc program.c -o run -lm
Computer A generates this answer: 1179908154 (wrong)
Computer B generates this answer: 142913828922 (right)
My guess might be because they are running on different architectures. But I really don't know.

I run some computations which give a big number of vectors (let's say 100 vectors, each one contain 2000 elements of type double). I want to save those data and import them into Excel.
I know I can save the results through in txt file. But it would be a very long file. Can I save the results in other more efficient file form that can be imported into Excel? and how?

How to get my data from the file and output, but now I am having trouble with my acceleration function. Right now, I have the acceleration function commented out and the output for acceleration at the bottom because if I try to run the program with them in it the program stops working. working with acceleration calculations and then finally outputting that acceleration.
//Program that reads the time and vertical velocity data and then calculates things from it
#include <iostream>
#include <cstdlib>
#include <vector>
#include <fstream>
#include <iomanip>
using namespace std;
bool calculateAccelerationArray (vector<double> t_array, vector<double> v_array, vector<double>
[Code] ....
The file I'm reading from rocketVelocityData.txt gives me the time and velocity.

The instructions: A nutritionist who works for a fitness club facilitate members by evaluating their diets.As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consume in a day. Then, she calculates the number of calories that results from the fat using the following formula:
Calories from fat = fat grams x 9
Next, she calculates the number of calories that result from the carbohydrates using the following formula:
Calories from Carbs = Carbs grams x 4
Create an application that will make these calculations
-DO NOT use global variables
-Create two variables in main that will hold the two results
-Pass fat and carbs by value, and the result variables by reference
-Output in main
The key with what you need to pass is this: Pass fat and carbs by value, and the result variables by reference. This is what I have to far but I don't understand how to "pass by value, and results by variable" ....
#include <iostream>
using namespace std;
void grams (int);
void calories ();
int main () {
//Get fat and carb grams

Code:
#include <stdio.h>
int main(){
unsigned char x, y=10;
scanf ("%c", &x);
[Code] ....
If I take out scanf and assign x a value then it works, but if I enter, for example, 10 into scanf it comes up as 234 rather than 100.

5. Four experiments are performed and each experiment produces four test results. The results are tabulated as shown below. Write a program to store these results in a two-dimensional array, A[4][5], then use a nested for-loop to compute the average of the test results for each experiment and store it in the 5th column of the array. Print the array.
1st experiment results: | 23.2 | 34.8 | 53.7 | 19.5 |
2nd experiment results: | 34.8 | 42.9 | 28.6 | 35.4 |
3rd experiment results: | 24.5 | 29.5 | 32.0 | 19.3 |
4th experiment results: | 36.8 | 31.6 | 43.7 | 29.5 |
6. Using the srand( ) and rand ( ) C++ library functions, fill an array of 1000 numbers with random numbers that have been scaled to the range of 1 to 100 inclusive. Then determine and display the number of random numbers having bvalues between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?

I need to write a program that will give me multiple calculation results.
#include <iostream>
using namespace std;
int main () {
int x = 8;
int y = 7;
[Code] ....
It only calculates the last two numbers: 1 and 0, so therefor it gives me 1.
But i need to calculate x and y each time they are smaller(incremented) by one digit.
Please note that the int calculation formula needs to stay.

Basically I have a few tables in my Database.
So I have one table that is like so:
Item_ID, Name, Parent ID.
1 , jeff , 5
and another table like this:
Parent_ID, parent_Name
5,jackson
What I would like to happen, when I run my code is that I'll get the following
Item_ID, Name, parent_Name
1 , jeff , jackson
DataSet DS = new DataSet();
if (this.OpenConnection() == true) {
mySqlDataAdapter = new MySqlDataAdapter("select Item_ID, NAME, Parent_ID from table1, table2", connection);
mySqlDataAdapter.Fill(DS);
dataGridView1.DataSource = DS.Tables[0];
//close connection
this.CloseConnection();
}
So this spit out parent ID = 5.
I've not worked with Dataset before and I was just wondering what is the best approach? Can this be done via a SQL command or will I have to replace the value(5) with the string(jackson) using a large IF loop to search and replace.

I had to write a simple program that prompted the user for various test scores and it would pump out his grade average at the end. I did that with no issue, however, my instructor wants me to add something to the end off the code and I'm not sure how to do that. My code is:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
string tempType;
float SumTest, MaxTest, TestAve,ProgAve,output;
[Code] ....
And this is what I'm supposed to add, the averages are supposed to have numbers from what the user gave.
***************************
Grade Calculator
Program Average
Test Average
Final Grade
