This code is near complete, the only task that is left is allowing the user to input a decimal and then two integers, or automatically using .00 decimal.
The automatic part: /*This is not correct.
printf(".%.2d
", number);
*/
But that does no good for me. Question: Do I have to create a some sort of while loop again, to allow the user to input a decimal followed by integer?
Code:
#include <iostream>
#include <cstdlib>
using namespace std;
int main() {
int j , i = 0, k = 0;
int number;
I've written a program that finds the maximum of a function. I now want to change it a little so that instead of evaluating the function y=x^2-7x-18, the program will ask the user to input an equation and then evaluate that equation. I'm really not sure of how to do so.
#include <iostream> #include <cmath> #include <cstdlib> using namespace std; int main() { int a, b, delta, x, y; double max= -1.8 * pow(10, 308);
Store the result into an array D of 8 elements. Your program should show the decimal numbers for every binary number. Print screen of 6 answers. This means you should try your program six times with different numbers in every run and show the printed screen result.
I'm trying to create a program that will take input from a user and calculate it in a do-while loop. The program does the calculation but the answer is wrong. The loop also doesn't work. The purpose of the program is to see how much an item will cost after a discount is taken off and tax is added.
I have been trying to finish this code (function) for a while now, but am stuck on the last part. In this code, I prompt the user to select a number of integers and any number of digits and then find the smallest and largest value within these digits. On the next part, I am supposed to determine which of the given digits the smallest and largest are located such that the output should be:
Digit _ can be found in integer number(s): _, _
Here is what I have tried:
Code: int digitSizeLoca() { int userNumInteger; int* iPtr; int* iPtr2; int* iPtr3; int value;
[Code] ....
Seems to do the job, but it always outputs 1, 2...
I am stuck on an exercise where i am supposed to use a loop to take user input and keep a running sum until the user enters a 0. the code i have so far is:
#include <iostream> int main() { using namespace std; int num; int total = 0; int x;
[Code] ....
The full text of the error message is: error c2678:binary'>>':no operator found which takes a left-hand operand of type 'std::istream' . and one more thing i was wondering, is there a difference between c++ and visual c++?
I have to write a program where the user will input integer numbers. How many numbers they enter is unknown, therefor you should use a repetition structure for the input. When the user is done, they will enter -1 to exit.
Create a dynamic array if the size=2( the initial size must be 2) Repeat until user enters -1.
I have to do this without using vectors.
This is what i have, I cannot figure out what to put in main. I was thinking of a do-while?
Code: #include <iostream> using namespace std; void resize(int *[], int); int main() { int *listDyn; int size=2;
The following program takes user input into two arrays and should then determine how many items are different by comparing them with a loop. The comparison always show zero correct answers.
#include <iostream> using namespace std; const int QUESTION = 20; //class for testing grades class TestGrader {
How to get this thing to work. All i need to do is ask user to input a name and then it brings out the line from the .txt file containing the information.
For example in my case I'm doing a member search function I'm required to ask user to input the name of the customer and then print out all the details (which consumes 1 text line in the .txt file)
Here is the code, This is the write to text file method (100% working)
I need the user to be able to input the number of decimal places they wish to have displayed in the output. Everything works fine as is, I just don't know how to allow for the user to input the number of decimal places they want the output to have.
Code:
#include<stdio.h> #include<math.h> #define PI 3.141592654 int main(void) { //Local Declarations int x; //desired number of decimal places float radius; //radius of circle float circumference; //circumference of circle
Create a program that will ask the user to enter a decimal value (1-999999) then display its corresponding binary numbers. Repeat this process until the value entered is equal to 0. Use the following Function Prototype:
void BinCodes(int value); Sample Input/Output: Enter a Decimal: 35 Binary: 100011 Enter a Decimal: 184 Binary: 10111000 Enter a Decimal: 0
I am learning c because I want to get back into programming microcontrollers, which I previously did in assembly. I wanted to make something fairly tight in terms of program memory and RAM to show me an output in binary form. When you are troubleshooting a file register or serial interface when you can see the actual bit values (on a small LCD for a micro-controller) and compare it to a datasheet.
Code: #include <stdio.h> #include <math.h> int main() { int i; int decimaltoconvert; int convertingarray[7]; int convertingarray2[7];
[Code] .....
Also, how might I go about putting that into a function that I could call?
LETTER OR '.' ? s LETTER OR '.' ? f LETTER OR '.' ? b LETTER OR '.' ? e LETTER OR '.' ? a LETTER OR '.' ? g LETTER OR '.' ? . VECTOR : [ SFBEAG ]
SENTENCE ?
But after this i can't write anything. Do you know why? I've never had problems with getline... when i used cin >> it read but only one word. Now it doesn't even let read...
Write a C++ application program to accept a signed decimal integer as input and output the equivalent 2s complement version in 16-bit binary. Include a space between every four bits in the output string. The input will only be processed by the application if it falls in the valid range that can be represented in 2s complement format with 16 bits. The range of a decimal number from - to + is -32768 to 32767.
I am making program that allows the user to determine how big the array size will be and then asks the user to make up numbers to fill the array. Every time run the program on Dev C++ it says "program has stopped working"
Heres My Code:
//Assignment 19 Program 2 #include <iostream> using namespace std; int main()
I'm trying to figure out why the binary to decimal part is not working correctly when the binary value finishes with a 1. In those cases, the decimal value shown in one unit smaller than it should be.
Code:
#include <iostream> #include <cstdio> #include <cstdlib> using namespace std; void Binary_to_Decimal(), Decimal_to_Binary(); //prototype for the 2 functions that contain the converters int main() //the menu { int a_Choice; cout << "Enter 1 - for binary to decimal" << endl; cout << "Enter 2 - for decimal to binary" << endl;
This program compiles, but has a bunch of logical errors. I know my problem is somewhere in the while loop that I have, but I can't figure out where. Here are some of the issues I am experiencing:
1. At the beginning of the program it asks you to enter a number, and when you do it does nothing while proceeding to the while loop where I have it asking the same question
Code: "Please enter a number between 1 and 20 (Enter 0 to stop) "; cin >> num; cout << endl;
I want to be able to eliminate that first statement but if I only run this in the loop without the above statement the program will display nothing on the screen and proceeds to stop.
2. This code runs fine, except that if you make a mistake, it will prompt you to enter a valid number, however; it ignores your first response if the number you enter is valid and asks you to enter a valid number anyway. Once you enter it a second time, it will accept it and the program will continue on.
Code: while(num != SENTINEL) { cout << "Please enter a number between 1 and 20 (Enter 0 to stop) "; cin >> num; cout << endl;
Also if you type in 0 on your first response, it will prompt you that it is not a valid number and ask you to try again, instead of stopping the program like it is supposed to do. On your second response the program will accept your 0 and stop the program correctly.
//Write a program that displays the roman numeral equivalent of any decimal number between 1 and 20 that the user enters. The roman numerals should be stored in an array of strings and the decimal number that the user enters should be used to locate the array element holding the roman numeral equivalent. The program should have a loop that allows the user to continue entering numbers until an end sentinel of 0 is entered.
Input validation: Do not accept scores less than 0 or greater than 20
#include <iostream> #include <string> using namespace std; int main() { // Declare constants and variables const int romanNum = 21; // Size of the elements in the array
In this simple end-of-chapter problem, the ages of two people are to be compared and determine who's older. The problem I'm experiencing is that the second user name input is being skipped and going straight to the second users age.
So while running the program it looks something like:
What is user ones name? <input name> How old are they? <input age> What is user twos name? How old are they? <input age> <if statement result>
Here's my code:
Code: #include <iostream> #include <string> using namespace std; int user_one_age; int user_two_age; string user_one_name; string user_two_name;
So I've got this form that a user puts in a numeric value into a text box. This value then has to be placed into a byte string of data so that it can be transmitted over as a packet. Bellow is what I have so far:
Code: Byte[] OUTBuffer = new byte[65];//Allocate output memory buffer Byte[] INBuffer = new byte[65]; //Allocate input memory buffer
if (setmSpeed == true) { OUTBuffer[0] = 0; //Not used, must be set to 0 OUTBuffer[1] = 0x85; //Command mode
[Code] ....
I've put in red the area where I'm having issues. I've tried different methods and have not been able to get this working yet. It only works if I speciffy the value manually as with OUTBuffer[1] = 0x85;, but I want byte 2 of OUTBuffer[] to be set with what I put in the text box.
I'm creating a program that should create a structure of a list of people entered by the user; the only problem I'm having is with the %c. When I have it, the loop only occurs once; if I put a %s, the loop occurs up to 25 times, but it doesn't write to the text file. Here is the code:
So im working with forks and creating 2 fork processes. One child and parent. What im trying to get the child to ask me for a value. Then the parent would start to figure out the value and keep trying. Once it figures it out its tells them you got it and simply stops the program. I cant seem to get the program to keep guessing and stop when the number is found which sends a sigint. Here's what i have so far.
I have this code here that counts the number of alphabetic letters the user's input,the number of characters total, the number of words and the number of "the" that was used. However now I need to alter the user's input to have two spaces after the end of each period, no spaces between a word or comma and each sentence has to have a capitalized letter and display them at the end. And I'm stuck on the altering part. I briefly started the 2 spaces after each period but it won't display anything.
#include <cstring> #include <iostream> using namespace std; int main ()
I have written a program and i had to pass an array into a function and now i have a variable for the subscript of the array and i was the user to input data, specificlly a string, more specifically first and last name without having to create two arrays, i have to do this with other things in the program as well, here is part of the program:
int addFunc(const int totNum, string city[],string state[],string street[],string name[], int addNum[],int zip[],int telNum[],double bal[],int dateLp[], int addCount, int accNum, int usNum)//function will add a new account { int countAf = 1; if (usNum < 20)
[Code] ....
it should be able to take firstname space lastname
