C++ :: Program Outputs Extra Lines Of Garbage
Mar 22, 2013The program works, other than if I place the cursor below the last line in my merch file, the program outputs a line of garbage. The only solution I could find is to leave the cursor on the last line.

Visual C++ :: Detecting Garbage Chars In CString
Feb 1, 2013How do I detect garbage chars in a CString. Actually I'm reading some data from COM port. In some certain condition it will give some garbage as a version no. Now I need to show _T("N/A") in case of there is any garbage.
My solution is to check for a Valid char or integer. If found its correct else Garbage.
C++ :: Program That Inputs A File / Performs Binary Division And Outputs Remainder
Sep 30, 2013For class I need to write a program that inputs a file (the dividend), performs binary division on the file (using 0x12 as the divisor), and outputs the remainder(checksum).
I have researched binary division algorithms and I get the general gist, but I'm still unsure where to start. How would I store the dividend and divisor? As two arrays of bits?
Then, I need to figure out how to perform shifts and XORs on the the binary numbers. Maybe I should use bitwise operations?
C :: Compiling Warning - Output Is Garbage
Mar 23, 2013I'm working on my program that takes input of the employees' first and last name, their payrate, their deferred from check and also the amount of hours they have worked which then the gross is calculated and also the taxes are calculated by an external function. In the program design it is necessary to put arrays which I have done, but when i compile I receive warning messages
Code: warning: format '%s' expects argument of type 'char*', but argument 3 has type 'double'
Warning: format '%f' expects a matching 'double' argument [-Wformat] which I believe is causing my program to just give me garbage when I run it. What do those warnings mean?
Code:
/* Name: Arturo
Date: 03/22/13
Purpose: To learn
*/
extern void calculate taxes(float gross,float deferred, float *ft, float *st, float ........i);
void ovtHrs(float *hrs_wrk, float *ovt_hrs, float hrs, float *gross, float payrate);
void netPay(float gross, float deferred, float ft, float st, float ssi, float *net);

C++ :: Arrays Of CStrings - Garbage Output?
Mar 20, 2013Here's my code:
struct Member {
char *name;
char *address;
char Interests[][10];//<------problem
int numofInterests;
Numbers digits;
[Code] ....
Now the Program:
newMember.Interests[numofInterests];
newMember.numofInterests = numofInterests;
for(int i = 0; i < numofInterests; i++) {
printf("Enter %s's %i interest: ", newMember.name, (i+1));
[Code] ....
it's a array of cstrings, but i can't figure out how keep it from outputting garbage, i'm assuming it's because i didn't end it with a null terminator but when i did, it didn't work.

C/C++ :: Integer Division As Opposed To Real Division?
Sep 28, 2013I have the following details
double x= 1.5
double y= -1.5
int m= 20
int n= 4
my question is 5 * x - n / 5 at which what would n / 5 equal to, I think its zero since its integer division? or would the 5 be considered a real number?
C :: Convert Scanf Output To Long Double And Discard The Last Newline
Apr 18, 2014My goal is to read a one line file of a comma separated numbers into a floating point array. The numbers have up to 25 positions after the decimal. I'm having two issues with the following code.
1) atof() seems to be returning zeros every time. Why?
2) The last number includes the new line character. How do I get rid of it?
Note that I adapted the scanf command from here: The power of scanf() - [URL], and don't completely understand it.
Code:
#include <stdio.h>
#include <math.h>
//The following will be calculated in the real program.
#define DIM 1
#define N 8
int main()
[Code]......
In the "real" program, N is calculated and known before reading in the file and the file will always have 2 times N numbers.
C++ :: Using Vectors And Strings / How To Output Name With Lowest Age
Nov 5, 2013I have to write a program in C++, without using a selection sort, that outputs the name you enter with the lowest age. You input 5 names with ages and at the end it outputs the youngest person. This is what I have so far:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
int main()

I Know for the second for loop there has to be if statements in it but I am so stuck on what to write next.
C++ :: How To Reverse Nibble In A Long Long Int Variable
Apr 1, 2015I have a long long int k=0x0000888804eaad0e
And i need the reverse of this (nibble wise) in other long long int variable.
That is i want the result to be = q=0x0000e0daae408888;
Or the result also can be like this = q=0xe0daae4088880000;
How to accomplish the above?
C++ :: List Of Vectors (vector Of N Vectors Of M Elements)
Mar 19, 2014I create a list of vectors (a vector of n vectors of m elements).
std::vector <std::vector <int> > vsFA (n, std::vector<int>(n));
How I assign values? I try below, but not worked
void armazenaFA( std::vector <int> &vFA) // this function only knows about vFA
{ vsFA[n] [m]= simTime().dbl();
OR
vsFA[n].push_back(simTime().dbl());
}
C++ :: Create Two Vectors And Then Loop Through The Vectors
Sep 19, 2014This is probably a very basic question, but I need to create two vectors and then loop through the vectors and output each pair that is found.
The user will input min1 and max1 with step1 for the first vector and min2 and max2 and step2 for the second vector. Then the loops will go through and return the combinations will return each pair of the two vectors.
So if I input min1=1 and max1=10 and step1=1 and same for vector two the return would be:
[1,1]
[1,2]
.
.
.
[10,10]
This is for part of a homework assignment, but I can't continue on the assignment without first getting this simple part to work.
C :: Cannot Get A Division To Work

No matter what I input for the values of 'Start', 'End' and 'Interval', the value of 'SizeL' always seems to be -2.
C++ :: How To Check If A Vector Contains Garbage
Jan 29, 2015So i have this code:
if (get_brick_at(Position(row, column)) == NULL)
Where get_brick_at is defined like this:
>Brick& get_brick_at(const Position & p) {
return board[p.get_row()][p.get_column()];
}
Now, of course this does not work since the compiler cannot convert from long int to a Position. So how do i know if the return value of get_brick_at is garbage?
I also have a couple of other situations where i want to return some kind of NULL-like value under certain circumstances.
My question is: How do i handle situations like that?
C :: How To Find A Remainder Of A Division
Jun 11, 2013I want to find the remainder of the division between a and b, but without using the reminder operator a%b.I thought to subtract b from a as long as a>b, that will give the remainder, but I don't know how to write it in code.

C :: Writing Garbage Data To File
Mar 21, 2013Im programming client/server app that client provide the file name then the server send it to client then the client will save it ..this is part of code in client
Code:
char buffer[1024];
printf("FIle is being downloaded ...

So i have 2 problems ::
1st one is when i write to file the file permission i cant define it with data type mode_t ,so the file does not open at all after creation...
2nd one is: the data in buffer is less than 1024 ,the data wrote to buffer but with garbage data . How to make the file read only the real data with garbage ??

Jun 27, 2013Code:
#include <stdio.h>
#include <stdlib.h>
// Define doubly linked list structures
typedef struct link singleLink;
typedef struct trashLink singleTrashLink;
struct link {
[Code] ....
Alright, my code is almost complete, I just can't get the clearFromList function to work correctly.
Here's what the program does, in a nutshell:
- Create two doubly-linked lists, one to hold numbers 0 through i, the other to hold a randomly generated list of numbers no greater than i to be "trashed". The same number cannot be "trashed" twice.
- Go through the main doubly-linked list and "skip over" the numbers that are listed the trash doubly-linked list (i.e. "delete" them without actually freeing them).
- Free both lists at the end.
I still have to free the trash list, but that's easy. I'm just stuck getting the clearFromList function to "skip over" each number in the main list that is added to the trash list.
C/C++ :: Vector Of Class Outputting Garbage Values
Jun 21, 2014I have a class that uses std::vector. I push back class objects onto the vector but when I try to cout the data members (with get functions) I get garbage values.
Here is the class:
#ifndef JOBS_H
#define JOBS_H
#include <iostream>
#include <iomanip>
#include <vector>
#include <string>
using namespace std;
class Jobs{
[Code] ....
I know I am missing the implementation of several functions but I'm just testing my vector to see if it is working and it isn't. The getBlockValue() function should output 0 for each job. When I push back one object the output is 0. When I push back 2 objects the output is 0. However when I push back 3 objects I get random values. Why is this? I thought vectors were dynamic?
C/C++ :: Tokenize Mathematical Expression - Garbage Value In String
Feb 14, 2014I wrote a program that tries to tokenize a mathematical expression, inserting the tokens in a list of strings. The list is as follows:
typedef struct listOfStrings {
char **array;
int size;
} ListOfStrings;
There is even a function to initialize the listOfStrings. The thing is: I'm printing a token every time it is complete and every time it is inserted in the list. The output is okay. However, when all tokens are processed and I call function print_list_of_strings to print the tokens again, the first token is printed with a leading garbage value if the input for the program is "3 + 4 * 2 / ( 1 - 5 ) ^ 2 ^ 3". How is this possible? The code for printing the list is as follows:
void print_list_of_strings( const ListOfStrings *const lPtr ) {
int i;
int numberOfElements = lPtr->size;
if ( numberOfElements != 0 ) {
for ( i = 0 ; i < numberOfElements ; ++i ) {
[Code] ....
The list just prints --- if it's empty, although this isn't the case for the program I'm writing. Also, if the input is "1 + 2", everything goes fine. The code for inserting at the list is:
int insert_at_end_of_list_of_strings( ListOfStrings *lPtr, const char *const str ){
int lengthOfStr = strlen( str );
int numberOfElements = lPtr->size;
if ( ( ( *( lPtr->array + numberOfElements ) ) = ( char * )malloc( ( lengthOfStr + 1 ) *
