C/C++ :: Stringstream Doesn't Pass Its Value Along

Dec 21, 2014

I just wanna have a very simple function that reads values from a text file row by row. The first value is passed along from the stringstream to my float data[] but after that it doesn't pass along anything. The strange part (for me at least) is that the stringstream contains the values it should contain, but they doesn't wanna end up in data[].

main.cpp
#include <fstream>
#include <iostream>
#include <string>
#include <sstream>

C++ :: Stringstream Consecutive White Space

Oct 1, 2013

So I have a text file named test.txt on the root of my c:/drive.

I finally managed to arrays working and reading into them, but when I started looking at the data in the array I noticed that stringstream was not "grabbing" a specified space. LINES 83-88

The text file contains the following (note that there is an intentional space after the first word):

I ' m s o r 0 y 4 D a v e , 5 12 12 12 3 7 f 11 2 i d 5 8 1 c 5 n 10 t 5 7 17 2 3 h 7 2 .

I need that space to be caught in the steam, there will always be only one space after a various first word, but I need it in my array and stringstream doesn't catch it.

if you need to run it, just copy the text to a file named c:/test.txt

When you run the code, you will see after the 3rd iteration it skips the space, is there a way to change this, so I can focus on the decryption algorithm??

#include <iostream>
#include <fstream>
#include <vector>
#include <string>
#include <stdio.h>
#include <sstream>
#include <cctype>
bool is_number(const std::string& s){
std::string::const_iterator it = s.begin();

C++ :: Read Text File To Stringstream But Keep Line Feed

Jun 6, 2013

I build this function in my C++ code. I run the on a UNIX box, build HTML file to use in Windows.

In HTML file building code, I have only a string variable hold the contents of this text file (from unix) & add it into HTML file.

The issue is that when I view the HTML file on windows, it shows all the lines in the text file as one line. I think it lost the CRLF.

My question is when I add lines from text file (reading one line at a time) in UNIX, how do I maintain CRLF ( ) in the stringstream variable so that it will display on HTML in Windows properly, all the lines as it is in unix.

I am aware UNIX uses for line end.

string TextFileToString(string filename) {
string line;
stringstream dosString;
ifstream inFile;

C++ :: Stringstream - Split User Input Into Words Separated By Space

Apr 20, 2014

I trying to get input from the user and split into words that separated by a space.

string s = "1 2 3";
istringstream iss(s);
int n;
while (iss >> n) {
cout << "* " << n << endl;
}

The code above works fine but i want to get the string from user. the code below only prints the first word and trashes rest of the words in the sentence.

string s ;
cin>>s;
istringstream iss(s);
string n;
while (iss >> n) {
cout << "* " << n << endl;

C :: Assign Integer Value To Unsigned Char Array But It Is Not Storing Integer Values

Oct 25, 2013

I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet

Code: uchar uc[100];
for(i=0;i<100;i++)
{
uc[i] = i;
}

The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.

C++ :: Changing Integer Into New Integer With Simple Mathematical Operations?

Jun 15, 2014

changing a 9 digit integer into a new 9 digit integer through simple mathematical operations. For example, I need to change 123456789 into the new digit 456123789. Sometimes I need to change a 9 digit integer into an 8 digit integer. An example is 789062456 into 62789456. I can ONLY use simple mathematical operations (addition, subtraction, multiplication, division and modulo).

C/C++ :: Converting 8-byte Integer To String Based Integer

Oct 15, 2014

Complete the function myitohex so that its converts 8-byte integer to string based hexadecimals.

Ex: printf("0x%s",myitohex(64,hex)); should printout "0x40" on the screen
char *myitohex(uint8_t i, char *result){
???
return result;
}

I wrote:

#include <stdio.h>
#include <stdint.h>
char *myitohex(uint8_t i, char *result){
*result = i + '0';

[Code] ....

0xp gets printed out which is wrong. I think *result = i + '0'; is wrong. What changes should i do on this row ?

C :: Integer Sum Using For And While Loops

Mar 6, 2015

I have an assignment that calls for a C program using a for loop AND a while loop that will receive an integer (called daNumba) and double it -- Using the integer the program will call the sumFor function and then the sumWhile function. These functions will both sum the values from daNumba to (daNumba * 2) ifdaNumba is positive. If daNumba is not positive it will add the values from (daNumba*2) to daNumba. Both functions will receive the value of daNumba and return a summed value. The only difference between the 2 functions is that sumFor will only use for loops and sumWhile will only use while loops. We are not to use arrays.

The program compiles without error. So far my while loop works for positive integers, but not with a negative integer (I have it commented out) I cannot get the for loop to work properly This is what I have so far -- I am stuck....

Code:
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
int main () {

C++ :: Factorize An Integer Into P And Q

Jul 8, 2013

i have the following problem to solve.... im unable even to start with an idea....can anybody help me giving an idea how to do this problem?

the problem is:
___*****____
Write a C++ program that factorize an integer n into p and q.
Step1. reads an integer n from the keyboard.
Step2. Write a for loop as below to check if there is any factor j > 1.

for (int j = 2; j <= square root of n; j ++)
{
If (n % j == 0)
{
factorizable = true;
break;
}
}

Step3. If there is no such factor, print the message n is not factorizable. If there is such a factor j,
check programmatically if j is a prime and n / j is a prime Also check if j and n / j are the same.

C++ :: Can Get Length Of Integer?

Oct 3, 2013

The programming problem is supposed to take a decimal number from a user and turn it into a binary number. Here is my code:

for (int i=0; i< count; i++) {
binary[i] = decimal % 2;
decimal = decimal/2;
} cout << binary[2] << endl;

decimal is the number entered by the user.

binary [] is the char array and count is... you know how many times the for loop will turn. So my question is, how do i know the length of the number ? Any function that shows the integer length ? because its impossible to know what count is equal to. like 100 is 3.

C++ :: How To Specify 0 As Unsigned Integer

Mar 25, 2014

Is it really needed to specify 0 as an unsigned integer? I mean 0 is always 0 regardless it's signed or not, no? In the below example is the 0U really needed?

#include <stdio.h>
unsigned invert(unsigned x, int p, int n) {
return x ^ (~(~0U << n) << p);

Now I'm getting the value of id i.e "DisplayImages.aspx?id=3" from DailyDarshan.aspx and want to display the images of each respective link according id.. when I click on "DisplayImages.aspx?id=4" link so it has to show the if(id == 4) images...but The problem is int id its not taking value itself.on DisplayImages.aspx.cs page I must have to define the id. for e.g. I wrote int id =3; on DisplayImages.aspx.cs file so it shows the images of id = 3 on each and every link.. Tell me what should I do to take value from another page or else how int id takes value by itself...

C/C++ :: Integer And Float Value?

Feb 28, 2014

this is my code

#include<stdio.h>
main()
{

[Code]....

N=1st number M=2nd number(accrding to my prof we will name it N and M
ctr= increment of factorial of N, ctr2= increment of factorial of (N-M)

the problem is when i got the factorial of N / factorial of (N-M) i need to get the last non zero digit. so i use mod if it has zero in it. but mod can be only used with an int value. and when i change it to int value, the value of fact1 which is a float change

C :: Reading Integer From Stdin

Mar 26, 2014

I am aiming to read an integer from stdin(pointed to the uart) and echo it with the uart interrupt service routine. there is a simple retarget file along with the main code shown below. So far i can read chars (char x[32] but i am struggling with int.

I have gathered that i need to use the scanf function to read an int from the pointer defined in fgets.

My output is giving me weird values, i enter 8 and ill get a random 3 digits back. I have a feeling its a problem with the input buffer.

Code:
//------------------------------------------------------------------------------// Cortex-M0//------------------------------------------------------------------------------
#include <stdio.h>#include <time.h>#include <rt_misc.h>
#include <stdlib.h>#define AHB_LED_BASE
0x50000000#define AHB_UART_BASE
0x51000000void UART_ISR(){

C :: Setting Flags In 32-bit Integer?

Oct 18, 2013

I am trying to create the lparam for the WM_KEYDOWN message. I know this is the C programming forum, but my code is standard enough to apply here. According to Microsoft, the lparam must be formatted like this : lParam The repeat count, scan code, extended-key flag, context code, previous key-state flag, and transition-state flag, as shown following. Bits Meaning 0-15 The repeat count for the current message. The value is the number of times the keystroke is autorepeated as a result of the user holding down the key. If the keystroke is held long enough, multiple messages are sent.

However, the repeat count is not cumulative. 16-23 The scan code. The value depends on the OEM. 24 Indicates whether the key is an extended key, such as the right-hand ALT and CTRL keys that appear on an enhanced 101- or 102-key keyboard. The value is 1 if it is an extended key; otherwise, it is 0. 25-28 Reserved; do not use. 29 The context code. The value is always 0 for a WM_KEYDOWN message. 30 The previous key state.

The value is 1 if the key is down before the message is sent, or it is zero if the key is up. 31 The transition state. The value is always 0 for a WM_KEYDOWN message. ( WM_KEYDOWN message (Windows) )^ I'm troubled by setting it into the 32-bit value, and I get confused about what exactly happens when the logical or and the bitshift operators are used. I tried to use them below in my code by looking at Stack Overflow for setting a bit. I also don't know how to test for the endianess of my system, and how to handle it if it's big endian or little endian. Here is my code so far :

Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <math.h>

C :: Unsigned Integer Representation

May 15, 2014

Consider this piece of code from the following website: [URL] .....

Code:
unsigned intx = 50;
x += (x << 2) + 1;

The website above says the following about the code:

Although this is a valid manipulation, the result of the shift depends on the underlying representation of the integer type and is consequently implementation-defined.

How exactly would a legal left shift operation on an unsigned integer result in implementation-defined behaviour?

C :: Integer / Floating Conversions

Apr 27, 2013

I got the following to compile and execute, but I don't understand how this works. Here is the code verbatim:

Code:
// Basic conversions in C
#include <stdio.h>
int main () {
float f1 = 123.125, f2;
int i1, i2 = -150;
char c = 'a';

[Code] .....

Okay, so first we have some variables declared as integers, floats, (and that char what it's doing). On the same lines we have values assigned to some of those variables. At first the "f2" and the "i1" confused me, but I think they're just variables whose type has been declared but have not received a value. So far I think I'm good. Then we get into the routines

I think​ I understand the first one. i1 didn't originally receive a value assigned to it, so when it says f1 = i1, then f1 (123.125) just becomes an integer, simple enough.

Then we get to the next routine and I'm like what dafuq??? So first we have f1 (123.125) being set to i2 (-150). wtf? So does that mean f1 is now going to have the value of -150? Vice versa? How are they becoming equal? Or does it have nothing to do with the values of the variables at all and just the type??? I'm just totally lost.

The output of that line is "-150 assigned to a float produces -150.000000." Which makes perfect sense to me written in plain English, but I don't understand how the C code works ....
