In unix if you create and open a file by using 9 digits numbers in the open function it seems to work but in C++ you only don't have a parameter to do that rather you have ios_base. Just wondering if there are owner,group and world settings that can be …

O_RWDR opens a file for read and write and pmode allows you to specify permission for each of the users? WHAT DOES IT MEAN BY WHAT PMODES AND O_RDWR ARE AVALABLE ON YOUR SYSTEM? CONSIDERING I AM USING VISTA I HAVE NO IDEA. I HAVE THE ABILITY TO READ AND …

and how i would go about fixing it? main [code] #include <iostream> #include "Format.h" #include <fstream> using namespace std; int main() { Format format; //string word; char in; ifstream infile; bool a=true; bool b=true; bool c=true; while(b==true) { cout<<"to quit type 'q'\n" <<"enter 'c' to get from console\n" <<"enter 'f' …

Random numbers appear and i have no idea where they are appearing from. Problem is in << operator. Not sure how to fix it. Main #include <iostream> #include "Format.h" using namespace std; int main() { Format format; format.setJustification('l'); format.add_word("one"); format.add_word("two"); format.add_word("is"); cout<<format; return 0; } Implementation #include "Format.h" #include <vector> …

Here is a link to the actual project. I could easily use getline for the phrase. Don't need to overload it to read in phrase. [url]http://home.earthlink.net/~craie/122/projects/framed.phrase.html[/url]

Please explain. Does it automatically include the default constructor?

I understand the concept but i don't know when to use and what my teacher expects when he says overload certain operators.

When you use getline(input,inputline) and you delete part of the inputline does it also ignore from the input file?

IT is defined in the back of my book but can't be found in my program.

ITS ALL THE WAY AT THE BOTTOM OF MY IMPLEMENTATION FILE. MAIN [code] #include <iostream> #include <fstream> #include "line_test.h" using namespace std; int main() { //open up file to be read string input; ifstream in; cout<<"enter file name which needs to be opened\n"; cin>>input; in.open(input.c_str()); while(!in) { in.close(); cout<<"the input …

why do i get undefined reference to error in my main with regards to isvalidname. It says undefined reference to... in my isvalidname i check if they enter in first name, char ws and then last name. Then i want to print out everything that i have deleted on that …

gives me error main /* The purpose of this lab is to open a text file and then make a copy of it */ #include <iostream> #include <fstream> #include "Interface.h" using namespace std; int main() { //open up file to be read from string input; ifstream in; cout<<"enter file name …

i am supposed to make 2 functions called find and they are supposed to find a character or string if they are similar when i do this progam gives me weird error: "use of search ambigious" "first declared as class search here. //main [code] #include <iostream> #include <cstdlib> using namespace …

it needs to make sure numbers aren't duplicate and are ordered. maybe change my cout statements to arrays? Thanks. This is what program is supposed to do input Q 1,2,3-5,6-7 output do problem 1,2,3,4,5,6,7 of Q. [code] #include <iostream> #include <cstdlib> #include <sstream> #include <string> using namespace std; int main() …

here's my code, don't see why it doesn't print out [code] #include <iostream> using namespace std; int main() { cout<<"enter a passage into input to find out how difficult it is to read\n"; string passage; cin>>passage; char letter; int space=0; while(letter!='\n') { if(isspace(cin.peek())&&letter=='\n') { cout<<"from space"; space=space++; } } cout<< …

so input would be Q1,2,3-5 output would be do problems 1,2,3,4,5 of Q [code] #include <iostream> #include <cstdlib> #include <sstream> #include <string> using namespace std; int main() { cout <<"enter the problemset and number""\n"; //problems represents name and numbers string problems; char quote; char num; string number; //gather name if(cin.peek()=='"' …

i have created a C string of my variables and guessing i need some king of loop to check each character after it gets it?

so i find the period or whatever the sentence ends in. Then I create a substring from that and delete the part which contains the end character. Then i keep count of it.

if it contains quote it cuts it out, then i am stuck on part when i just enter in a problemset without a quote or single quote. Then it doesn't gather numbers correctly but stores the entire string [code] int main() { cout <<"enter the problemset and number""\n"; //problems represents …
