C++ :: Longest String Does'n Print On Same Line

Aug 4, 2014

I try to learn string class, resolving some problem, but i have some dificulties.The is ok, but when i print the longest string it does'n print on the same line.I enter the number of string, after that i enter the first string until i introduced from keyboard "#" character. I enter the second string and so on.Look at these example :

For i = 3;

Text[0] : I learn class String#
Text[1] : I dont learn class String#
Text[2] : String#

It print me like that : Text[1] :

I dont learn class String More than that look at the next example :

For i = 3;

Text[0] : I learn class String#abcdef
Text[1] : I dont learn class String#
Text[2] : String#

You see that in the first sentence i have continue to introduce some characters after # character and look what is happened :

Text[1] : abcdef
I dont learn class String

#include<iostream>
#include<string>
using namespace std;
int main() {
string text[100], cuvant;
int i, j, m, lung = 0;
cout << "

C++ :: Program To Print Longest Common Subsequence?

Sep 12, 2014

I found this implementation on a website for printing the longest common subsequence. But it gives wrong answers for some reason even though the code seems right to me.

Here is the code:

#include <iostream>
int lcs(char *X, char *Y, int m, int n)
{
int L[m+1][n+1];
for(int i = 0; i<=m; i++)

[code].....

What is wrong with this code?

C++ :: Read Line By Line From Text File To String

Jul 5, 2013

I have a text file (test.txt) with the following data:

01,05,25,20130728
01,06,25,20130728
01,07,25,20130728
01,08,25,20130728
01,05,25,20130728
01,05,25,20130728
01,05,45,20130728
01,05,65,20130728
01,05,85,20130728
01,05,35,20130728
01,05,25,20130728
01,05,35,20130728

I want to read this to one string called line. So far I have this code:

string line;
ifstream myfile ("/home/Test.txt");
if (myfile.is_open()) {
while (myfile.good()) {
getline (myfile, line);
for (int a = 0; a <= 335; a++) {
cout <<line.at(a);
} }
myfile.close();
}

so far its only printing the first line and then throwing an instance of 'std::out_of_range'

C++ :: String Operation While Reading Line By Line From A File

May 12, 2014

I have to read the information about logic gates from a file. The file format is shown below:

Code:
gateOne = NAND(inpA, inpB)
gate2=NAND(1,2)
3 = NAND(23,25,26)

As, it can be seen from the above structure that whitespaces are not same everytime. So, to deal with this situation, i am using boost library to remove all whitespaces from the line which is being read and then try to find the name of gate and its input. My code is given below which is able to correctly find the gate names and its first input...but my code is not able to find the second, third and so on input names.

Code:
//C
#include <stdio.h>
//C++
#include <iostream>
#include <sstream>
#include <fstream>
#include <string>
#include <cstring>
#include <boost/algorithm/string/erase.hpp>

C/C++ :: How To Print New Line Without Carriage Return

Jul 28, 2014

I am using C++ to write data into a (.ini)file. However, when I try to print the value '0A' I am getting '0D 0A'. (this is what I see when I copy the output to HexEdit). From what I can figure out, '0A' is the ascii for 'new line' so write function automatically adds the '0D' which is 'carriage return'. What I want is to print 0A alone. how can I do this?

Note: Windows it is working fine, but linux it is not working...

unsigned char arrRes[4];
int N = 10;
memcpy(arrRes,&N,4);
std::ofstream Output(LUT_OUTPUT_FILE_BINARY,std::ios_base::binary | std::ios_base::out);
Output.write((const char*)arrRes, 4);

here 10 means 0x0a but it is printing 0d,0a...

C++ :: How To Enter And Print X And Y Coordinates On One Line Separated By Comma

I'm trying to enter an 'x' and 'y' coordinate on only one line separated by a comma. But I keep getting a syntax error. Here are the lines of code I'm using. This has to be simple. What am I doing wrong with this code?

Code:
cout<< "Please enter the x and the y coordinates of the first point,"<<endl;
cout<< "use a comma to separate them. " <<endl<<endl;
cin>> "You entered: " >>x1>>",">> y1 >>"for the first point" >>endl;

C :: Print Listing With Line Numbers - Cannot Execute / Run Program

Feb 18, 2013

The problem is with the first "Type and Run," where the code looks like this:

Code:
/* print_it.c--This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>

void do_heading(char *filename);
int line = 0, page = 0;

[Code] ....

I am using the gcc compiler in Ubuntu 12.04 LTS and I get the following error:

Code:
print_it.c: In function "main":
print_it.c:36:15: error: "stdprn" undeclared (first use in this function)
print_it.c:36:15: note: each undeclared identifier is reported only once for each function it appears in
print_it.c: In function "do_heading":
print_it.c:49:16: error: "stdprn" undeclared (first use in this function)

I was told that "stdprn" can be recognised by a DOS based compiler and the book says I can try using "stdout" instead. It looks like this now:

Code:
/* print_it.c--This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>

void do_heading(char *filename);
int line = 0, page = 0;

[Code] .....

It compiled OK with the gcc compiler but I only get this when I run the program:

Code:
Proper Usage is:
print_it filename.ext

I am not sure whether I should continue looking into this but even when I tried compiling and running it on Windows, the .exe file won't even launch. The other ones do but this first one doesn't.

Questions:

1. What should be done to make this program run?
2. Even though the book says "don't care" if the reader does not understand the items (It's Day 1/Lesson 1), I would still like it to run as I don't want to experience compiling and running problems in the future. Should I even bother doing this section of the book or is it obsolete and should be skipped?

C++ :: Finding The Longest Path In A Graph

Dec 29, 2013

I was asked to find the longest path in a graph. I was thinking about using Dijsktra's algorithm after multiplying all the weights with -1 and run the program in normal way and find the shortest path. And then I'll multiply with -1 again and get the longest path. I think this should give me the longest path, do you think it would work? And also, I'm dealing with considerably big data, such as 1.000.000 nodes and many more edges. etc. and I have a time limit of 2 seconds and memory limit of 128mb. Any other data structure instead of Adjacency Matrix? Because I'm pretty sure it will exceed the limits.
