I'm reading in a string from the command line into a char array followed by a series of ints which are read into an int array.
The command line
Code: lab3 word word word 0 0 2 3 results in the following output:
Code: Word: .N=▒
Number of Words: 0
Word: .N=▒word word word
Number of Words: 3
Num: 0
Num: 0
Num: 2
Num: 3
Here is the source code:
int main(int argc, char *argv[]){
if(argc < 2){
//command line must have at least three arguments (one
//char, one integer)
printf("Error: invalid number of arguments
I'm having an issue with output, luckily everything else works!! I'm working with Mixed Numbers and operations on them. So, here's the code I'm testing with:
I have to convert a binary value from an input file (the name of which is given by the user) and then convert the binary to decimal value and print that in an output file.
Right now it is compiling just fine with no error messages, but when I run the program, it doesn't end or print to the output file.
I'm trying to make a simple temperature converter with a menu that lets users pick which conversion to perform. But, it won't seem to print the right conversion. It just prints the same temperature that I inputted.
for example:
#include <iostream> using namespace std; //prints the menu void userMenu(){ cout << "Temperature Calculator" << endl << endl;
I have managed to make a program that permutates a string with repetition.
I ran it to permutate "abcdefghijklmnopqrstuvwxyz1234567890" with a limit of 5 characters.
This took a little over 5 hours for my pc to process this and I ended up with a .txt 403MB in size. Needless to say I am unable to open this .txt in notepad without Notepad.exe not responding and me having to end the process.
So what I want to do is modify my code to break up the output in to several files rather than one. Possibly all permutations starting with a in one file, b in another, etc.
Here is my current code: #include <iostream> #include <string> #include <sstream>
[Code]....
As you can see it currently appends permutation.txt with all output. I would like it to make files like this permut_5char_a.txt, permut_5char_b.txt, etc.
// DEBUG3-4 // This program contains a class for a cylinder // Data members are radius and height // The volume is calculated as pi times radius squared times height // If no height is given, it's not a cylinder - it's a circle!
#include<iostream> using namespace std; //declaration section
To generate output data, I'm printing a bunch of vector contents to files. Because the type of variable can differ between vectors, I wrote a templated printing function to print out whatever the content of the vector is. It looks like this:
I added the fixed because some larger values were being printed in scientific notation. Everything works well. My test code includes 3 vectors of doubles and 3 vectors of unsigneds. All the unsigneds work well and two of the doubles work well, but the third doubles vector prints nonsense unless I disable the fixed.
The calling code is the exact same. I know the values in the vector are correct, because a) if I comment out the "fixed" flag it works, and b) one of the unsigned vectors is sorted based on the values in that double vector (after it is printed, so the sort cannot corrupt the vector print) and works perfectly.
The "nonsense" looks like chinese/weird characters, if that matters.
I have a big problem with a function, I wrote this function in order to get a line from an HTML (Or XML) file, until a specified delimiter (not always or ... It can be everything..)
Here is my code :
public static String GetLineUntilChar( String url , char delimiter , String postData, String referer, String cookie ) { try { Uri uri = new Uri("http://127.0.0.1//site.html"); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); request.ContentType = "application/x-www-form-urlencoded"; if (!String.IsNullOrEmpty(referer)) request.Referer = referer;
these are the errors that I'm getting from an online c++ compiler
// main.cpp:4:10: error: #include expects "FILENAME" or // main.cpp: In function 'void permute(char*, int)': // main.cpp:17:9: error: 'f' was not declared in this scope
I don't understand how to print full_string to a file!// otherwise, I know that it gives the correct output -- 90 strings.
#include <string> #include <iostream> #include <fstream> #include >ios> // line 4 error using namespace std; char full_string[] = "112233";

//iter_swap – it just swaps the elements pointed to by the respective pointers without changing the pointers themselves. so, it's basically equivalent to the function:
// min_element – finds the location of the minimum element that exists in the given range. in this case,
it is the char* pointer pointing to the location of that element. it can be implemented like:
char *min_element(char *start, char *end) { // end is 1 beyond the last valid element if(start == end) return end; // empty range char *min_pos = start; for(char *iter = start+1; iter != end; ++iter)
I'm having trouble printing the text in between separators like commas, periods, and at signs. I'm following Jumping into C++ Chapter 19 Practice Problem 2.
This is what I have so far:
Code: #include <iostream>#include <string> usingnamespacestd; int findNeedle (char separator, string inputLine) { int needleAppearences = 0;
[Code] ....
And this was my test run output:
Enter the contact info. one, two, three, ,? , one two, th three, Program ended with exit code: 0
I am trying to save 5 persons names to a struct, and then printing them afterwards, shortly before the program ends. I tried to print the char string out right after it has been copied over, and it showed fine, but when i try to write it out right at the end of the program (its in a separate function) the terminal just prints gibberish.
the function looks like this:
Code: int printUser(){ printf("Following patients have been recorded in this session: "); struct database patient1; struct database patient2; struct database patient3;
[Code]...
the output looks like this(as you can se in under structest, that it shows the correct string, it also uses printf):
So I have an array of char called s.This array has many words inside, each one separated by ''.The words are sorted by length (from bigger to smaller).I have have a char matrix with random things inside (it was not initialized) caled mat.I want to copy the first word from the array s to the matrix mat.
Code:
int nlin, ncol; /*number of lines and collumns.*/ int c,l,a,q; char mat [1000][1000]; char s[1000]; }
[code]....
I can't see where this is wrong, but, when i test it, it clearly is not right. for example, if the input is 3 lines and 3 columns for the matrix and the word is crate, the output is :
I am trying to write a program for printing all the combinations of a string. Why this program is giving the error message.
"First-chance exception at 0x761bc41f in word.exe: Microsoft C++ exception: std::out_of_range at memory location 0x0026f6b4.. Unhandled exception at 0x761bc41f in word.exe: Microsoft C++ exception: std::out_of_range at memory location 0x0026f6b4.." when i try to run this in MVS 2010
How to print a string in reverse order(for example: "today is Wednesday " to "Wednesday is today"). My professor said we should begin with a null string and build it one word at a time.
#include <iostream> #include <fstream> #include <string> using namespace std; int nwords(string);
i couldnt solve the algorithm exactly. The program asks the user for a string. "Bugun h@v@ cok g'uzel" for example. then the program asks for another string. If that string doesnt exists in the main string program should say there isnt any substring. If it exist then the program should print the remaining part of main string. For example:
Write the first string: Tod@y weather is be'@utiful write the substring : ug >>ugun h@v@ cok guzel write the substring :wldnqwbdbj >>there isnt any substring Here where i came so far
#include <stdio.h> int main() { char mainstr[50],substr[50];
write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.) Does this follow the criteria? This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?
#include <iostream> #include <cctype> #include <cstring> using namespace std; int main() { char let[100]; cout << "Enter what you would like to be UPPERCASE: ";
For the last part of this problem, if player 2 loses the game of hangman, I need to display the letters they did get right. In order to do that, I believe that I need to traverse vector v for the elements that exist in the string hiddenword, and then print those characters that match.
I want to process data (using fstream) and print out the progress. This doesn't work with cout <<, only with puts, but this causes a line-break but I want a progress bar like this : [=====================].
I've already searched for an hour in the reference and with google and I dont manage to put a string without a linebreak:
while (ein.good()) // loop while extraction from file is possible { c = ein.get(); // get character from file if (ein.good()){
I am writing a small editor for RSL coding, and ive got an external program "3Delight" to compile the code.
Now i want the output from that exe to be captured in a string once the compilation is comlete, but all of the methods ive found online dont seem to work for me. Ive tried using _popen which works if i run a normal command like "dir", but not with the exe.
This is the function ive been using that works with the normal commands
std::string exec(const char* cmd) { FILE* pipe = _popen(cmd, "r"); if (!pipe) return "ERROR"; char buffer[128]; std::string result = "";
[Code] .....
and this is how i was calling it, but it just returned an empty string, even though the exe printed "Compilation successful"
I have a program that will convert a string of numbers into a barcode that consists of :'s and |'s. But the only issue I have is that the numbers are all being output backwards.
