C/C++ :: Program To Find Min / Max Values Of Two Ints / Doubles And Chars
Jan 31, 2015
I'm supposed to create a program that will find the min/max values of two ints, doubles, and chars, It's not completely done but here's what I have so far.
It's giving me an Error 1 error LNK2019: unresolved external symbol "public: __thiscall MinMax<int>::MinMax<int>(int,int)" (??0?$MinMax@H@@QAE@HH@Z) referenced in function _mainC:UsersDerickDesktopCiss243Week3 Assignment2Week3 Assignment2Main.objWeek3 Assignment2
Header file
#ifndef MINMAX_H
#define MINMAX_H
#include <iostream>
using namespace std;
template <class T>
class MinMax
[Code] ....
I don't know why the site is adding in extra bits of code like /> in certain areas, it's not there when I paste it in and it's not in my code ....

I am trying to figure out the larger 2 out of 3 integers when i call them into a function from main program so far i have . How to write a simple function that will take 3 ints and find the sum of the higher 2?
Code:
int findsum(int a,int b,int c)// will find the highest int and return it to our main program {
int max,max2;// this sets our local variable max
// next we will find the larger of our first 2 variables
if( a>=b)
[Code]....
How to get the second highest number and add it to max...

I am getting a string from the consle and that all works fine. I'm expecting a string of number, ie 123456.... I store that fine in my string object. I then need to take each individual number, ie 1, and put it in a vector then take the next number, ie 2, and put that in the next element in my vector.
Everything i've found and does eaither takes the entire string and stores it as an int, or takes the ascii representation of the number and stores that. How do I seperate each individual number and store them seperatly. below is a few different variations i've tried that doesn't produce my desired results.
cout<<"Please type the memory memory frames (numbers 0-9) to be used to simulate the input memory "<<endl;
cout<<"Your input: ";
string line="";
cin>>line;
cout<<"
Please wait while your input is processed and validated..."<<endl;
[code].....
the only thing i havn't tried yet is string streams and i don't necessarly like using them. Am i going to have to go that route? will that even work?
EDIT:I forgot to mention that this is being done on linux and then ported to unix.

how to compute the averages for 6 values that have been computed from a for loop,
I mean once the for loop finishes it prints me six different values classified into 3 groups as shown down:
group1 has value1
groupe2 has value2, value3, value3
group3 has value5, value6
I want to find the average for each group.
considering the number of values in each group might change. this is the code for finding the values:
for (int i=0; i<n; i++)
{
if (value < 25)
{

In the following code I want to iterate through "Win32_OperatingSystem" to find all variables and their values. Using GetNames() I can get the names of all the variables but the subsequent Get() call fails to return a value.
Code:
//connect to WMI
std::wstring wmiClass = L"Win32_OperatingSystem";
CComPtr< IWbemLocator > pLocator;
HRESULT hResult = pLocator.CoCreateInstance( CLSID_WbemAdministrativeLocator, nullptr, CLSCTX_INPROC_SERVER );

I'm trying to write a program to find values for arctan of x by using taylor series. An initial value of x is given by the user and then it should print solutions from arctan(x) to arctan(1) in increments of x+0.1. It prints correctly but gives incorrect values after the initial x. I'm new to c and need some way to 'reset' the functions f1 and f2 for each increment of x (I think...)
Here's the code
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <iostream>
#include <fstream>
using namespace std;
int main() {
/* Define the beginning of the program and each variable. Also opens a text file to be written to */
FILE *f = fopen("arctan.txt", "w");
[Code] ....

I have to do a project where a file with 60 rows and 17 columns is stored in an array. The purpose of the project is to find all the "peaks" and "valleys". A peak is considered a number that has a higher value than all 8 of its neighbors, while a valley is a number that has a lower value than all 8 of its neighbors. Here is an example where peaks are bolded and valleys are underlined.

3939404247492730
3131313232334435
I'm having trouble coming up with the code that will find values that are higher/lower than all 8 of their neighbors.

im using a for loop to find the index values of the tied high scores and store them into string list then reference list in the second for loop to output it to screen however it isnt letting me use an array with index i as an index its self.
void printHighest(Student s[], int length){
int index;
string list[10];//you're never going to have more than 10 people with a tieing highscore.
index = findMax(s, length);
[Code] ....
For the time being I simply removed the idea of string list and just put the contents of the second for loop into the if statement above it. However, I am still curious as to if I can reference an index of an array in an index of another array.

I seem to have reached a dead end in a program I am attempting to write.The purpose of the program is find the smallest, largest, and average values in a collection of N numbers. It needs to get the value of N before scanning each value in the collection of N numbers.I'm having trouble creating comparisons for each set. I have a feeling because of the way I structured my program, I'm unable to make a proper comparison. Maybe my approach was wrong as soon as I got to the for statement to loop N sets and N numbers.Here is my code so far:
Code:
#include <stdio.h>
int main (void)
{
int num_sets, num_of_integers;
int count, count2, set, sum = 0;
int num, avg;
}
[code]....
/* Here is where I would continue to attempt to make a comparison between sets to determine smallest to largest */
return 0;

I am so close to finishing this program. It will find the median of an array of 5 values. I have one last error that I cannot seem to get to go away. Here's the code:
#include <algorithm>

#include <iostream>
using namespace std;
int main() {
int integer1, integer2, integer3, integer4, integer5;

I have many random strings that look something like this:
" 55.343 Char 1.3825 asdf 0.1853 500 1.1359 4.0000 1 100 4.5043"
Notices how there are ints and chars and doubles in the string.
How do I remove all non-doubles for a string like this? The chars and ints may be anywhere within the string.

Why the program continues to prompt me for a vaild number even when the correct number( a gpa) is entered. I'm not sure if the problem lies in the isDouble function or the getDouble?
*/ Determines whether the string holds a valid double. Checks if each character is digit and there is no more than 1 decimal point.
*/
bool isDouble (const string &str) {
int decimal = 0;
for (unsigned int i = 0; i < str.size(); ++i){
if ( str[i] == '.'){
decimal++;}

I use the following function to read doubles from a binary file:
Code:
int64_t read_current(FILE *input, double *current, uint64_t position, uint64_t length)
{
printf("asked for %" PRIu64" samples
",length);
printf("reading from %" PRIu64 " to %" PRIu64 "
",position,position+length);
union{
double d;
uint64_t i;
}
[code]...
As long as position+length doesn't exceed the end of the file, all is well. However, if it does, weird things start to happen. In particular, the apparent length of the file (that is, the value of "read" after the function has finished) becomes dependent on "length"). I know that "position" is never past the end of the file.

Take this string for an example, "asdf 9.000 1.232 9.00 23.1 545.3"..Is there a way to replace any of the doubles with another double? Example: Replace the first "9.000" with a "10.0". I am aware that string::replace will do the trick, but how do I make it work for arbitrary cases? By arbitrary I mean that I don't know the size of the string to be replaced, I just want to be able to replace any number with a given number.

I made this pthread/mutex program that makes deposits and withdrawals of random amounts. I have it working how I wish, however, I cannot figure out how to make it so that the random values are only within certain ranges. For example, let's just say I want all deposits to be random doubles between 50.00 to 100.00 and withdrawals between 25.00 to 50.00, or something similar.

Ok so I have a class that takes integer fractions and I want it to be able to take doubles also depending on what the user inputs. How would I go about this? I was thinking templates ...

I am really desperate on trying to make my code work. The code is to find the eigen values of any given matrix of dimension NxN. The input can be the diagonal of any NxN matrix alongwith its subdiagonal. The code works fine for N~350 or so but when i go beyond that these errors appear.
First-chance exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000.
Unhandled exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000.
But as i have never declared any variable statically and when i dynamically allocating memory with variables it should work like it does for smaller N values.

I'm trying to validate my input. I require for the user to enter six doubles and if they don't then I want them to re-enter the information. Here is my code:
Code:
while (1>0) {
printf("Please enter arguments in the order: negative mass, positive mass, initial x-position, initial y-position, initial x-velocity, initial y-velocity:
");
if ( scanf("%lf %lf %lf %lf %lf %lf",&MassMinus,&MassPlus,&Pos[0][0],&Pos[0][1],&Vel[0][0],&Vel[0][1]) != 6) {
printf("Not all numbers were assigned!
[Code] .....
At the moment it just waits if you enter less than six numbers and if you enter any more than 6 it just ignores anything after the sixth number (so pretty much does nothing). Also if I entered 1 2 a b 3 4 instead of entering six numbers it would register that as 1 2 0 0 3 4 but I want it to make the user input the numbers again. I'm also aware that "while (1>0)" isn't good programming form but I'm not really sure what to use instead?

Given a stack with an equal amount of even and odd numbers: 4, 22, 15, 3. The output should be in any order: [even], [odd], [even], [odd].
int main() {
Stack<int, 4> stk; stk.ClearStack(); int x;
for (int i = 0; i < 4; i++) {
cin >> x;
stk.PushStack(x);
[Code] ....
Output is:
Wed Feb 19 20:09:10 2014
4 7 5 22 //input
22 5 4 //output
Press any key to continue . . .
I know the logic fails if the first number is not even, but I cant seem to figure out another way to do it.

I have some paper work to do about a game I should be able to play with my class mates. We should be able to send and recive a struct concerning about the 'moves' of the pieces at the game. This struct is made of 4 ints, simple as that.
I had a previous paper work to do where I'd have to send ints and that was ok, but now that I have to send a struct I'm failing to do so. This is What I've tried:
//SERVER
struct message{
int code;
int piece;
int x;
int y;
}send;
bytes_sent=write(new_socket,&send,sizeof(message));
cout<<bytes_sent;
So far so good, I see 16 as bytes_sent's value.
On the other hand:
//CLIENT
struct message{
int code;
int piece;
int x;
int y;
}recive;
bytes_recvd=read(my_socket,&recive,sizeof(message));
cout<<bytes_recvd;
I always see 0 as the bytes_recvd's value.
