C++ :: Sorting Float In A Vector Of Objects
Nov 2, 2014I've a vector of objects that I can get my float value from by accessing it through a method.It's not a pointer of vector of objects though.
Meaning it's something like vector[i].getFloatValue().
However,how do I sort the float values by descending order since I access it through a method?
C++ :: Two Vectors Of Float - Sorting In Reverse Order?
Jul 15, 2013I have two vectors of float that I need to sort in reverse order. reverse() seems to work for one of them, but not the other. I have toggled between sort() and reverse(). for one vector, the expected behavior is seen and the order reverses. For the other, there is no change in order.
This is very simple code, so it's hard to imagine what is going wrong.
Code:
vector<float> vec1, vec2;
vec1[0] = 14.1102; vec1[1] = 14.1145;
vec2[0] = 15.8508; vec2[1] = 26.0842;
sort( vec1.begin(), vec1.end() );
sort( vec2.begin(), vec2.end() );
[Code] ......
Printout is,
Code:
vector 1 sort
14.1102
14.1145
vector 2 sort
15.8508
26.0842
vector 1 reverse
14.1102
14.1145
vector 2 reverse
26.0842
15.8508
You can see that the order of the first vector did not change. Am I right in suspecting that the numbers are too similar for what ever method reverse() uses to determine the difference between values?
C++ :: How To Generate Sounds Of Mixed Waveforms
Aug 23, 2013I have used beep() and sound() functions. But both of them generate sounds of only fixed frequency. Is there any way i can generate a sound of mixed waveforms. I am currently using this code, but it isnt reliable at all times and for all frequencies,
for(i=0;i<500;i++)
{
sound(500);
delay(2);
sound(250);
delay(2);
}
C :: Mixed-type Contiguous Memory Buffer
Mar 1, 2014I'm writing a program that communicates with another program over TCP/IP. I need to assemble contiguous buffers of mixed data to send to the server. For example, one of the messages must contain multiple 32-bit integers and 64-bit floats, each in its own appropriate field. I also need to receive and decode similar buffers.
The Windows TCP function "send(socket s,char *buf, int len, flags)" takes a pointer to a character array to send. Likewise, the TCP function "recv(socket s,char *buf,int len,flags)" takes a pointer to a character array to fill. I've tried creating structures describing the send and receive messages, with the fields appropriately laid out. But the CODE::BLOCKS compiler complains when I try to hand send and recv the pointers to the structure variables. Am I on the right track, or is there a better way to do this?
C++ :: Mixed Expressions / Loops And Formatted Output
Feb 22, 20151) ask the user to input a mathematical expression in the following format:
NUMBER Operator NUMBER Operator NUMBER

How to output the answer of the users equation. Is there a function that includes all math operators (+,-,/,*)? Would i need to write each possible scenario using if statements?
C++ :: Reading Mixed Data Types From A File
Mar 28, 2015How to properly read data from a .txt file.
If I have data stored in a .txt file, which is formatted/stored like this:
Code:
Apples and Strawberrys
10
Cherrys
12
Pears
16
Grapes, Melons, and Peaches
20
I know that if I read/extract, and print the data like this;
Code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
ifstream dataFile("test.txt");
string textData;
[Code] ....
Each line of data is stored in the string "textData" and printed to the screen, exactly as it was stored in the .txt file. So, all is clear to me up to that point.
But, what if I wanted to store each line of text in the string "textData", and store the numbers/integers into a separate variable called "numberData"? How would I retrieve and store the numbers (in the above example .txt file, every 2nd line) separately from the text?
For now, to keep things simple, let's assume that the data in the .txt file is stored/formatted as in my example (1 line of text, 1 line containing a number/integer, ...repeat) so, there is no need to test if the retrieved data is actually text or an integer, before it is stored in the appropriate variable type.

View 1 Replies View RelatedC :: Putting Float Numbers Into Double Array
Jan 29, 2014So I have a double array, where I'm inputting float numbers to certain points in an array. Sometimes, the numbers that are printed out are completely different from what I put in.Here is the part of the code:
Code: .
while( token != NULL ) {
num = atof(token);
test[j][i] = num;
printf( "
%s, i is %d, j is %d
", token,i,j );
printf( "number is %f
value test of i,j is %f
[code]....
Why the float num prints out fine, but when put into an array becomes garbage?I'm taking string values from a csv file and turning them into floats, but no problems seem to crop up there.I reset i when appropriate and increment j when needed, so I don't think my problems are from incorrect array values (though they might be)
C++ :: Possible To Use Data Type Double Or Float For Array?
Mar 9, 2014Can you use data type double or float for an array? ie

or

C++ :: Read Float Numbers From Keyboard And Store Them Into Array Of 10 Elements
Jan 10, 2013I have to complete a project that i want to read float numbers from keyboard and store them into an array of 10 elements.! Every time that a number stored into array i want to compare with previous one if they have +-10 difference .. I want to keep only 10 elements into my array so every time that i give value a[0] replace a[1], a[1] replace a[2],a[2] replace a[3]. . . .and a[10] deleted.. So when all elements of the array are similar with +-10 values print out the array.!

Dec 4, 2013I need to create a main function with a one dimension dynamic array with float data type. The total number of array elements must be controlled by a user input from the keyboard.

C :: Sorting Array Of Size 10
Nov 18, 2013I am trying to sort an array of size 10. If I was given:
Code: int List[Size] = {29, 11,12,10,3,26,13,15,19,2};
I need the program to sort all the odd integers and put the even integers to the back of the array. Like so:
Index: 0 1 2 3 4 5 6 7 8 9
Value:29 11 3 13 15 19 12 10 26 2
And it returns the number of even integers in the List. In this case it returns 4. All I am given to start with is
Code:
int evensToRead(int* const List, const int Size){

C# :: Sorting 2 Dimensional Array By Value
Jan 9, 2014Here is what I have, I have a 1D Array being added to a 2D Array and I need to Sort them by value value 3 in the 2D Array, while maintaining a specific amount. Here is what I have so far:
public static void CheckHS(string[] HS) {
try {
GeneralData.HighScores[10, 0] = "11";
GeneralData.HighScores[10, 1] = HS[1];
GeneralData.HighScores[10, 2] = HS[2];
GeneralData.HighScores[10, 3] = HS[3];
//Need Sort Data - Bubble Sort?
}//end Try
catch (Exception ex) { MessageBox.Show(ex.Message); }
}
I am thinking bubble sorting but I remember reading about something faster. Unfortunately I can't find it on the web. The idea is that there will be always 10 Values and 4 Columns on the 2D Array. [The 11th Row being empty at the end of it.
