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)
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.
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.
// Automobile Mileage.cpp : Defines the entry point for the console application. // //Programmer: Ryan Youngen
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);
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:
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[])
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 would like to know how to replace a value with the variable that ii is equal, i mean like a=5 i want to be able to replace the number 5 by the letter a when needed in printf. ofc i want to use this for an actual purpuse and meaning what i gave was a mere example and thxx. BTW DONT jUst DROP a few lines of code that would make it work
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:
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> using namespace std;
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
I've copied and pasted my code. The main program, the calculateTaxes.cpp function code and my makefile. I am using the makefile to link these two codes together but I get an error when I type 'make' in the command line.
I receive the error code: assign2c.cpp.text+0x169): undefined reference to 'calculateTaxes(float, float, float*, float*, float*)' collect: ld returned 1 exit status make: *** [main.exe] error 1
