C :: Do While Loop Error
Feb 19, 2015
While trying to redo everything in c i have an error on a do while loop and i don't understand i've corrected everything else but i don't understand why the error occurs even though it says how to fix it it says error expected ) before token -line 18 part of code
Code:
int main(){
Beep (523,1000); // sound at 523 hertz for 1 000 milliseconds
char cPresent;
do
}
[code]....
this is just extra bits i've added on to the assignment but I've worked on the c++ code for a week now i have less than a day to redo it

I am just starting out with loops and I have run into an syntax error and for the life of me I cant find out the issue. Before it has been an issue of me forgetting to close my brackets but I am pretty sure I did that this time. I am trying to have the program keep looping the main menu until the user inputs a correct number.
float total_Bal = 0.00;
char user_Choice;
do
{

The purpose of this program is to unscramble the user's input. for example if the user entered 'ftooabll' the program would print 'football'. find the error that I am making....
Now, this only works for strings that are contained in the file wordlist. That being said, I would like this to repeat this search multiple times. Currently, the process is being repeated 7 times, but it only works on the first iteration. The code and sample input/output is below.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define NUMLOOP 6
void sort_string(char*);
[Code] ....
Sample input/output: (note: all data has been verified to be in the wordlist)
Enter string:
4132dcba
abcd1234
Enter string:
4132dcba
Enter string:
4132dcba
Enter string:
4132dcba
Enter string:
4132dcba
Enter string:
4132dcba
Enter string:
4132dcba

In a record I have IDs of type int but some may repeat. These IDs also got sales of type float. I wish to compare the IDs number of times they appear and of match found accumulate their sales and put it in another struct. However if an ID is found which is new I pass it to a function to initiate sales..but my code never reach second ID, given I am trying with two IDs.. given IDs in transFile
ID Sale
12345 870
90909 100
I enter these two in transFile and match it with masterRecord. 12345 is matched and updated likewise but 90909 is never executed or matched in checkID function..
void sync_trans_files(unsigned short int count, master masterRecord[], char transFile[]){
const short int weeklyemployee=25;
//read number of records from transFile;
struct trans{

My loop is outputting data incorrectly. I have inbound web data that come in sets of 7. I am trying to in insert the 7 records into a vector and then display the vector content followed by a new line.
Code:
char buff[BUFSIZ];
FILE *fp = stdout;
char * cstr = buff;
vector<std::string> vrecords;
while(std::fgets(buff, sizeof buff, fp) != NULL){
for(int i = 0; i < 6; ++i){
[Code] ....
expected output:
Found buy!

I have a working lab project with a loop error. Code posted in second post. Here's the requirements:
*
- program has to be able to handle file failure
- must loop (prefer to use a while loop here), read in the data, calculates values, etc. and then output the results.
*
The input data file includes
1. a 1 or a 0 indicating that there is a set of employee data following
2. the hourly rate of the employee
3. the humber of hours worked
4. the number of dependents
5. a 1 or a 0 indicating whether the employee is full time (1=full time).
Problem: At first I wouldn't loop back... so I moved the curly brace above the return0;

I am getting an error with my while loop(feels dumb) when running this code that I am allowed to modify. It is to remove all instances of an element within the list.
The loop is whithin this function:
void arrayListType<elemType>::removeAll(int location)
I have attached both the header file and main function file in .txt format.
void arrayListType<elemType>::removeAll(int location)*
Attached File(s) :
header.txt (12.23K)
main function.txt (2.95K)

#include <string.h>
int Menu ();
int ValidInt(int , int );

We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.

I have tried to submit this topic before but i didn't submit my whole code and it was removed. So here it is. All I am trying to do is load form2 from form1 then back to form1 from form2 for a certain number of times the get out of the loop. I am new to C-Sharp and it seems as though I cant seem to figure out a way to do this.
Here is form1 and form2 code. I have commented out a few things I have tried.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;

Given a for loop:
int i;
for(i = 0; i < 1000; i++)
;
How many nanoseconds, or microseconds or milliseconds does it take for each iteration? And why do some use it as a timer mechanism?

I already made a nested for loop into a while loop (below this) and now I'm trying to make the outer for loop into a do while loop, but it's not working.
#include <iostream>
using namespace std;
int main () {
int len;
int j;
int i;
[Code]....
And I can't make this code do the same thing. It stops after one loop, instead of continuing to the end. Why won't the loops continue?
#include <iostream>
using namespace std;
int main(){
int len;
cout << "Enter a number: ";

I need to convert the following while loop:
count = 1;
while (caloriesForItem != 0, count != numberOfItems )
{
cout<<"Enter the calories: ";
cin >> caloriesForItem;
totalCalories += caloriesForItem;
count++;
}
This is what I have come up with:
totalCalories += caloriesForItem;
for (count = 1; caloriesForItem != 0; count != numberOfItems)
{
cout<<"Enter the calories: ";
cin >> caloriesForItem;
count++;
cout << "Total calories eaten today = " << totalCalories << endl;
}
However the output is not the same?

I for the life of me can't get my logic straight. I have 2 lists, 1 a list of text, and the other a list of int.
Here's my main list: List<string> ListNeedToADD = ListOfSPSExt.Except(ListOfReportExt).ToList();
Here's my second list:IEnumerable<int> result2 = Enumerable.Range(1, Convert.ToInt32(myValue)).Except(hostList);
I need to loop through my main list, ListNeedToADD, and for each item in that list, grab 1 value from the 2nd list and send those 2 items to a method. Something like this:
foreach (string myString in ListNeedToADD)
{
foreach (var item in result2)
{
intSort = item;
insertReportLimits(attribTable, myString, intSort, con);
}
}
The problem with doing it the way I am above is it loops through ALL the items for each myString.
For my method, it needs to look like this: insertReportLimits(attribTable, "34257", 22, con); then it would move on to the next: insertReportLimits(attribTable, "34854", 27, con); etc etc.

I can't get out of my loop to fill the array. This array should stop and print after 10 inputs. but it keeps asking for input.
This is what my code is supposed to do. Use 0 as sentinel for an array. Only positive ints will be entered into the array. A negative int should result in an error message, then input will continue. The numbers will be inserted into the array in ascending order. Do not insert them then sort the array.
#include <iostream>
#include <cmath>
using namespace std;
const int arraySize =10;

What I need to do to get rid of the infinite loop?

");
}
while (test< 0 || test>4);

So I have a programming assignment.
Code:
#include <stdio.h>
int main(void)
{
int input;
int sum;
int i;
int t;
[Code] .....
So you input an integer ex) 30
the printing of t =(i+i)+1 and i++ is carried out until i=30, which is when the sum of all the t's is printed.
If the value you entered is not an integer, the loop ends.
I'm supposed to do this with one while loop, and no more. I can't use the for loop either.
How can I do this?
