I wrote a program that should check if phrase is in file and output the result.
File:
//////////////
Eat my shorts!
Ay Carumba!
Stupid Flanders...
////////
Why my program doesn't cout?
#include <cstdlib>
#include <cstdio>
#include <iostream>
#include <fstream>
using namespace std;
string checkData (char Input[], char dataB [], int nMAX){
[Code] .....
I get this error..In function 'main':
p6.c.text+0x6a): undefined reference to 'palindromeness'
collect2: 1d returned 1 exit status
This is program is suppose to check if a phrase is a palindrome or not.I need to write a function definition for _Bool palindromeness(char str[])but I am having a tough time figuring that part out. I am brand new to programming..this is my first class and I am just learning arrays and pointers.
So I have to write a program that outputs a check with correct spacing and everything.
Create a project titled Lab7_Check. Write a program that asks the user the check information and prints the check. The dialog should be as follows:
date: 2/23/2010
name: William Schmidt
amount, dollars: 23
cents: 30
payee: Office Max
your check:
William Schmidt 10/13/2013
pay to: Office Max $23.30
twenty three and 30/100 dollars
You may assume that a person always has the first name and last name (no middle names or initials). The payee name is also always two words. The dollar and cent amount are integers and the amount is always less than 100 dollars. Note that the dollar amount could be zero, in which case, when you spell the dollar amount, it should print "zero". The date is always a single (non-white space separated string). Your date, dollar amount in numbers and the word "dollars" have to vertically align.
This is the code I have so far.
#include <iostream>
#include <string>
using namespace std;
int main(){
string date;
string firstname;
string lastname;
[Code] .....
Code:
it = m_CoopTable->m_SparseMap.find(s);
if (it != NULL) //Error
{
return false;
}
This gives me compile-time error. it is an iterator to a hash_map
I have this simple code here:
Code:
#include <iostream>
int multiply (double x, double y) {
double result = x*y;
return (result);
[Code] ....
I get the answer 5.94 (which is what I'm looking for). I can't work out why the first example is not outputting a decimal number. I have set the variables as a double so I just can't see why this is not working for me.
I'm working on a CGI application. I'm trying to test my input with a switch statement and output the result with html tags to populate a web page. From within the switch, I've coded as follows:
HTML Code:
switch(mFunc) {
case 0:
cout << "<p><b>YOU ENTERED THE FOLLOWING TO BE CALCULATED:</b></p>" "<h2>"<< number1 <<"+" << number2 << "</h2>" << endl;
break;
case 1:
cout << "You've entered" << number1 <<"-" << number2 << "to be evaluated" << endl;
break;
I know that I'll need to put this in an html body with a content type as such:
HTML Code:
cout << "Content-type: text/html
";
cout << "<html><body>
";
Am I able to do that directly inside of the switch statement?
One of my class assignments is to create a program that receive a .txt file containing a students name and their grades as follows:
John K. 99, 87, 57, 89, 90, 95
Amanda B. Jones 100, 88, 76, 99, 86, 92
etc..
The number of students is unknown until run time. You have to take those grades and average them weighing the first (4) at 10% a piece and the last (2) at 30% each.
Then return an output file with the students name and their letter grade A,B,C,D,F based on their computed score. In addition, on screen it needs to display the average scores for each Q1, Q2, etc. as well as the minimum and maximum for each test on the screen. I am having a hard time in assigning the scores to a variable so that they can then be computed as an average and then used to determine a letter grade. I have begun to write the code and am a bit stuck..here's what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>

My project involves writing a c program to generate a set of 70 decimal numbers. I want to save the output (these 70 numbers) as a txt file. I tried the following:
1. prt scr of output screen and pasting it in notepad. NOT WORKING
2. going to DOS SHELL and doing the following:
c:TCBIN>output.exe>>output.txt
NOT WORKING. Text file is generated, but it does not contain output. It just says:
illegal command: output.exe
What do I do?
//code
ofstream outFile;
outFile.open("p4a.dat");
outFile << setw(8) << "90.0";
outFile << setw(8) << "75.0";
outFile << setw(8) << "36" << endl;

I am creating a program that allows the user to enter the number of days worked and calculates the amount of money gained by doubling the amount from the previous day, starting with .01 cents. The program works fine except for in day 3, the program adds .01 along with doubling the amount from day 2. Also I must use a List Box.

When the user selected this option, your program should be able to accept a character from the user and search for this character from the phrase. Your program should be able to identify the location of the character in the phrase. I've try the arrays but still can't go .....

The program adds 2 matrices that are 3x3 using arrays and then stores them into another matrix (array) and then it's edited to show a diagonal line of "0" through it, btw I'm pretty new to programming....

Code:
#include <iostream>
using namespace std;
int main() {
int x[3][3],y[3][3],c[3][3],i,j;

It works almost just fine lol, Except that the first portion of the diagonal line does not become zero and instead displays the normal addition result.....
The code below replaces lowercase characters by upper case and uppercase character by lowercase. Also, I should be able to break out of the loop when I enter 'exit'. It does what it is supposed to do. But I had to come up with a function to break out of 'the while loop'. Is there any shorter or more concise way to break out of the loop when 'exit' is entered?

Write a program to create an output file containing a customized loan amortization table. Your program will prompt the user to enter the amount borrowed (the principal), the annual interest rate, and the number of payments (n). The payment must be rounded to the nearest cent. After the payment has been rounded to the nearest cent, the program will write to the output file n lines showing how the debt is paid off.

#include <stdio.h>

The result it prints is 2684356604 on my 32-bit computer. The result I expect is as follows:
0xFF94 is 0000000000000000 1111111110010100 in binary.
Shift it right by 5:
0000000000000000 0000011111111100
Then take that result in shift it right by 27 (s is 32 and p is 5, so the difference is 27):
1111111110000000 0000000000000000
Now we use bitwise or:
0000000000000000 0000011111111100 | 1111111110000000 0000000000000000 = 1111111110000000 0000011111111100
That in decimal is 4286580732. So how does it come up with 2684356604?
