I just started by defining a stack class (stackDouble). I need to write a program that accepts an infix calculator expression, with the following operators (**, exponentiation, /, division, and, -, subtraction. The operator precedence is exponent, division, and subtraction.I need to use a stack of doubles and a stack of strings, of which I can write two classes, or write a single stack template. The user will input the expression just via cin, and there will be a # before every number, a ! before each operator, and a . at the end of the expression. '#', '!', or '.' can be input into a char variable, numbers into a double variable and operators into a string variable.
For example, the following would output 6:
# 3 ! / # 2 ! / # .5 ! ** # 2 .
As stated above, I already made up a stackDouble class. What would I need to do to create the other class (I don't think I want to do it with a template)?
Code:
#include <iostream>
#include <string>
using namespace std;
class stackDouble{
i try to write a postfix calculator program using stack in C++ the in put must be the infix expression but can dont know how to write a infix expression in put.
i'm trying to write a calculator. the user will enter the terms and they will be stored in arrays. i will be storing those terms in string arrays and then later turn them to double to work with them. but the user should be able to enter terms like sin(252) and the program should be able to recognize it and calculate it.
Given a set of different types of paired symbols; determine whether it is balanced or not (the opening and closing version of each type are paired correctly). Any other type of characters may appear in the input will be neglected.
For example: (**(*[*])****) is balanced, also [{}**[]**()]** is balanced. But ((*{*)*}) is unbalanced as well as [()***[]***{*(*)}.
Write a C++ program that requires a string containing and expression as an input from the user and check for balanced bracket pairs using stack data structure.
Here is my code which give me nothing when I run it.
#include <iostream> #include <string> using namespace std; class CustomStack {
i feel like im really close to completing this but i cant seem to get the result printed out i dont think im calling my evaluate function correctly and its not performing the operations..
#include <iostream> #include <stack> //stack header file using namespace std;
How to implement the main queue functions Enque() and Deque() using two stacks S1 & S2. You allowed only to call push () and pop() functions of the two stacks to implement Enque()and Deque() functions.
#include<iostream> using namespace std; const int size=5; int arr[size]; int front=-1,rear=-1; bool isfull() { if(rear==size-1)
Any example of a graph search algorithm that uses a recursion and linked list based stacks to determine a route from a single point on a graph to another single point on a graph?
I am still new to stacks and recursion and am trying to implement two functions using recursion to get the maximum element in a stack and copying one stack into the other but it keeps repeating some elements and i dont understand why!!
I was given a task to convert infix to post fix using both linked lists and stacks in the code so this is what i have written but the problem is it is giving me same error at three different places "missing function header(old style format?)
#include <iostream> #include <string> using namespace std; const int size = 100; class stack{ private: // Declare a structure for the list
I have an assignment to do a calculator in C, wich will work by clicking the numbers with the mouse, however i have a bug that when i hold the mouse and dragg it, it assumes that I'm clicking multiple times, also, when I click in an empty space the program creates a blank space on the calculator screen.
Code:
#include <stdio.h> #include <conio.h> #include <math.h> #include "..MouseHandler.h" // ajustar o caminho ao seu projecto #include "..calcSkinLib.h" // ajustar o caminho ao seu projecto #define PI = 3.1415;
I'm trying to create a program that will calculate the gpa of several different students, whose data are in a text file. The file looks something like this, with possibly more lines.
Mark 3 4 A 3 D 2 C 1 A Tom 2 3 A 2 C
The very first number tells us how many credit hour/grades will follow. I have a couple of problems though: From the code I've written I don't seem to get any data other than the first line. Also the gpa that does print out after the file runs is just a 0.00, rather than the actual gpa.
'm trying to program a BMI calculator in C for my assignment where the weight must be in KG and an int , and the height must be in m and a double value. The program should allow the user to input his weight(kg) and height(m) separated by a space and be able to calculate and display the BMI. My code is shown below :
However , after running the program , I constantly get a 1.#INF00 value for my result.The compiler did not show any errors so why I'm getting this value.I input my weight and height in this format "45 1.65" 45 being the weight and 1.65 being the height.
I basically just have to make a calculator that only uses getchar/putchar (printf is Ok for displaying errors) - Also, negatives must be error-checked. As of right now, my program will only work if there is exactly one space between the number, operand, and other number. No spaces, or more than one space, will give me some very weird digits. I also need to display the numbers with putchar, and not printf (as I did below), but I just really wanted a working program.
#include <stdio.h> #include <stdlib.h> #include <ctype.h> #include <math.h> int add(int input1,char operand, int input2); int subtract(int input1,char operand, int input2);
I am making a calculator where I will input 5 array of numbers and calculate those numbers with pointers or whatever you call it. I am getting an error like
I have to enhance my BMI program to tell whether the person is at optimal weight, under weight, or overweight and I cannot find the correct calculation. Here is the code I have so far that works for calculating the BMI.
namespace Body_Mass_Index { public partial class BMI_HW : Form { public BMI_HW() { InitializeComponent();
ive been learning from the book for 4 days and decided to make a different type of calculator out of boredom but im really having problems when i try to make it a loop? ive been scratching my head trying to work it out rewriting deleting etc but cant work it out
Code: #include <iostream> #include <string> using namespace std; int main()
In my calculator, I am trying to make it so that you put enter 1 to add, 2 to subtract, 3 to multiply, and 4 to divide. I am facing the issue of making it so that you must enter a number, however instead of it being any number, it must be 1, 2, 3, or 4, and if it is not any of those numbers, you must re-enter the number. Here is a little snippet of my code:
Code:
printf("Please enter 1 to add, 2 to subtract, 3 to multiply, or 4 to multiply: "); while (scanf("%d", &input) != 1) { while (getchar() != ' '); printf("Invalid option. Please try again: ");
The main point of the program is to calculate equations just like a standard calculator but I wanted to do it myself. I don't understand what the problem is right now but I've managed to create a program that asks for both values but somehow it doesn't want to ask for an operator (*, /, + etc). What's wrong with my code that the terminal skips the scanning part for the operator?
Code:
#include <stdio.h> int main() { int value1, value2, answer; char operator;
