C/C++ :: Programs Keeps Producing True - No Matter If Two Numbers Are Equal Or Not
Sep 25, 2014
In my program I am supposed to call isEqualTo with a user defined class type, and print out if my two numbers being compared are equal or not. I had to write two versions of this, one with just a template which works fine, but when I implemented the class, all the sudden my program just spews out true no matter if actually equal or not. Here is what I have so far:
#include "stdafx.h"
#include <iostream>
#include "UserClass.h"
using namespace std;
template<typename T>
bool isEqualTo(T value1, T value2){
if (value1 == value2)
[Code] ....

I calculate two numbers "R1",R2"
when i make
cout<<R1;
cout<<R2
i get
R1=51,9151
R2=51,915
when i make
Code: if (R1>R2) cout<<"i am here" he print the message
but they are equal. how i made limit the number of flottant to get equal numbers?

int main()
{
int a=0, c, d, N, K;
bool stopBool = 0;
[Code]....
This is supposed to find take a number N and K and find all numbers between 0 and N that equal K and cout the number of pairs that fit it but it doesn't work.

When you are creating a project or program, how do you number your versions?
Like when you release it, it becomes v1.0, am i right?
then every release or build after that might become v1.1 or v1.0001 or v1.0.1.2
Is there a certain global system for how you Number your versions or is it just up to the developer?

I have recently found this article: URL.....In their example, by declaring variables in other order, they saved 8 bytes. However, shouldn't compiler take care of it? Is it true, and should I declare variables more carefully?

My program works fine in all areas but adding the average every loop. It gives me a weird -1.#IND as an output, and it's supposed to calculate the total mileage each time I enter new values per trip.

I can't figure out why my makeString gets called first and the pString its called with contains garbage. I want my allocateMem to get called first, but my program is not going to that. What is wrong with the order of my code?

Why my calculate function is producing a zero?I feel like it may have something to do with there being zeros the arrays it takes. The arbitrary cout statements are just for my debugging purposes. Input is formatted as follows:
<int>
<int>
<string>,<int>,<int>
<string>,<int>,<int>
<string>,<int>,<int>
<string>,<int>,<int>
and so on
#include <iostream>
#include <string>
#include <sstream>
int** parse_input(int &num_items, int &pouch_size);
int* calculate(int &num_items, int &pouch_size, int *values, int *weights, int &max_value);

Something is wrong with option 1. For some reason it adds 1, 2, 3, 4 ... 5 onto the output and I can't think why. Here is a screenshot.
Also how can I make the output a little neater? I tried to use but it just looks horrible.
I had linked the source code! Why is there no edit button?!
#include<iostream>
using namespace std;
int main(){
int option;
cout << "Welcome to my program. Please select a following option.

I have done some programming or rather have written and implemented some algorithms in code (is there a difference? :-)) but am having some teething problems with a project I am currently working on.
To start with I am simply reading in the data from a .txt file into a vector. This is the code that I currently have:
Code:
#include <iostream>
#include <fstream>
#include <cerrno>
#include <vector>
[Code]....
This compiles fine but currently outputs a different integer everytime I run the program. I can remember having this problem when I started coding before using a different language and if I remember correctly it was quite easy to resolve. I thought it was because I had missed off the 'return 0' but it is something similar I think.

I am working on a project and decided to try something simple before I start adding items. I am calling a function from main and that function has a file pointer.
Here is my main.cpp
Code: #include <cstdio>
#include <string>
#include <iostream>
#include "main.h"
extern FILE *fp;
using namespace std;
int main(int argc, char *argv[])
[code]....
Here is the function:
Code:
#include <string>
#include <cstdio>
#include <iostream>
#include "main.h"
[Code] ....
My test file consists of several characters and digits. Nothing special and I at this point in time do not have any type of formatting that needs to be adhered to. I am simply wanting to read the file character by character and print it out. When I run the program, I get this symbol:
Code: If I use a printf statement, such as:
Code: printf("%s
", nextChar);
I get a segmentation fault.
My main.h Code:
#ifndef MAIN_H
#define MAIN_H
void scanner(FILE *);
//char getChar(FILE *);
#endif and lastly my scanner.h Code: #ifndef SCANNER_H
#define SCANNER_H
FILE *fp;
#endif

I made my own function to search if two given strings in my function are equal but the problem is if i pass two variable like hello,hello ... result is string equal but if i pass hello , hello also give me string equal because last 4 characters same to last 4 characters of hello ...
Code:
int getSimilarityOfTwoStrings(const char str1[],const char str2[]){
int str1Len = getStringLength(str1);
int str2Len = getStringLength(str2);
int i = 0;
int j = 0;
bool truefalse;

I'm making a simple calculator and have done it all right where you can input everything, all the functions are there, but when i run the program it will come to displaying the result and it will always equal zero, I just need it to say 8+8 = 16 rather than 8+8 = 0, i don't know whether its just displaying the results as 0, or not displaying it at all, the code will follow below:
Code:
#include<iostream>
using namespace std;
double num3;
double num2;
double result;
char operation;

This program that I've made works fine to find midpoint, but not distance. The distancefunction always returns a 1 (true). To try to see that it wasn't the math, I added cout.setf(cout.boolalpha) to see and got a result of "true".
//This program is a start to solve basic coordinatre plane distances and midpoints
#include <iostream>
#include <cstdio>
#include <cstdlib>

how to check if a specific index equal to null when i try to implement it, it gives an error for example:
vector < vector <double> > v;
v[0].push_back(0);
v[0].push_back(1);
v[0].push_back(2);
v[0].push_back(3);
v[1].push_back(10);
v[1].push_back(11);
v[1].push_back(12);
v[1].push_back(13);
if(v[0][4]==NULL) {
cout<<"empty"<< endl;

I am trying to write a simple program that produces different outputs based on entered age of two different users. Program should tell who is older and behave different if both users are older than 100.
Here is my program: Code: #include <iostream>
using namespace std;
int main()
{
[Code].....
Why program executes this when both users are obviously more than 100

The task is to return the number of bits set to true.Here is my code:
Code:
int cardinalityBS(PBitSet _this) {
int s, counter = 0;
for(s = 0; s < 31; s++) {
counter += _this->bits & 1;
_this->bits <<= 1;
}
return counter;
}
[code]....
The code is not working, since whenever I set _this->bits to a number, it returns me the wrong result.

is it true or false
a function like void myfun(int num){} can receive type "int var" but can't receive type "const int var"
AND
a function like void myfun(const int num){} can receive both type "int var" and also type "const int var"

My assignment : "Input the answer as the words true or false and put the user's answer in a boolean alphabetic variable."
My code:
bool T;
cout << "Type 'true' for lowercase or 'false' for uppercase";
cin >> T;
if (T == "true") {
cout << "Enter a whole number in decimal base: ";
cin >> dec;
cout.setf(ios::showbase);
cout << "Decimal " << dec << " to Hexadecimal with lowercase: " << setbase(16) << dec;
}
I'm not sure how to get 'true' as user-input as true for bool.
