While compiling i got this error,
C:UsersDervDesktopCensusQuestsAndAnswers.cpp|25|error: 'string' does not name a type|
I tried fixing it by adding #include <string>, using namespace std and by even using std::string but for some reason, it still gives the error.
Here's the code ^^
#include "QuestsAndAnswers.h"
#include <iostream>
#include <string>

Ok, so I'm writing this code and when I build it keeps saying cannot implicitely convert type int to string even though I declared my variables as string. Why is it giving me this error?
private static string Repair()
{
string result="";
string beep;
string spin;
Console.WriteLine("Does your computer beep on startup?:(y,n)");

I wrote a program that reads a list from a file and stores it in a string type vector. Now, I want the user to input a word so that the program can search the vector to see if that word already exists. I have used every possible way of reading input from the console and storing it in order to compare with the vector but it never results in a match. When I print the input string and the vector string they are exactly the same thing (or at least print to the console as if they were). I've tried using getline; using cin direct to a string var; using cin to a char array and then casting to string using string str(arr); I even added a newline at the end just in case and STILL I cannot get a match.
vector <string> currentSet; //read a list in from a file and has 9 items in it
cin.ignore();
string line;
getline(cin, line);
if(line == vector[0]){//if printed to console line is HEAT and vector[0] is HEAT
cout<<"match"<<endl;
}

I have an xml file with an IM node, i serialize it and get the property like:
public ImAddressDictionary ImAddresses { get; set; }
And then set the value like this:
contact.ImAddresses[ImAddressKey.ImAddress1] = sImAddresses; where the sImAddresses is a string.
I then get this error:

I am trying to make a program that can type a string into another window. I have gotten it to the point that it can type the string, just not correctly.

I want to use this array as part of my class. I have tried several different angles trying to get it to work but with out success. I have been checking to see if it works by simply using "cout << dayName[3];" It is printing nothing at all. What is the proper way to initialize this array of strings?
First I tried this:
const string dayName[] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
then I tried this:
const string dayName[7];
dayName[0] = "Sunday";
dayName[1] = "Monday";
dayName[2] ="Tuesday";
dayName[3] ="Wednesday";
dayName[4] ="Thursday";
dayName[5] ="Friday";
dayName[6] ="Saturday";

So Im working on my semester prject for my programming class. It is to make a roulette game. And Im working on getting my table set up but the intellisensor in my Visual Studio seems to not be working and recognizing the string variable type. Its not changing to blue when I enter it.
This program is a roulette simulation, designed to be used for online gambling.
#include <iostream>
#include <iomanip>
#include <Windows.h>
#include <string>
#include <ctime>
using namespace std;
//Function Prototypes
void welcome();
double getBalance();
[Code] .....
When I run the program it gives me an error as well sometimes. This one: Unhandled exception at 0x0f681f68 (msvcp100d.dll) in Roulette Final Project.exe: 0xC0000005: Access violation reading location 0x8bb59d35.
Which opens another tab named "iosfwd" and points to this bit of code:

How do I compare a string vector against an enumerated type? My code so far is:
void convertToLastFirst(vector<string>&names){
enum NameFormat{FIRST, LAST};
for (size_t i = 0; i < names.size(); i ++){
if (names[i] FIRST){
names[i] = LAST;
}
}
}
If we are using strcpy() for copying the string. As we are passing pointers to it It will copy the string & no need to return the string .This function will finely work with return type as void then why Ritchie has used it as char* strcpy()?

I have an assignment where I need to read in a phone number into any array and I can't use the string data type. Assuming I need to use the getline function, how do I do this? I'm guessing it's with the cstring or .c_str() functions? I don't know.

My assignment is : Please use C type strings ( array representation of strings). Write a program that will ask the user to enter a string. It will then regard that string as a worked-on string and allow the user to perform the following editing functions on it:
s – search
i – insert
a – append
d – delete
a – append
d – delete
r – replace
e – exit
s – search
This option will allow the user to search for a specified string in the worked-on string. If the string is
found, it will display the starting index (position) of the searched string in the worked-on string.
here is what i have so far.

I'm having some problems with changing an array of numbers of type char to type int. Every time i try to sum 2 array indexed values it returns some letter or symbol. Also, if i change the type of the array in the functions the compiler gives me an error message. I would also like to add that the problem requires that the first two arrays be char so each individual number gets assigned to a different value.
My current code is:
Code:
#include <iostream>
void input(char a[], char b[], int& size_a, int& size_b);
void convert(char a[], int size);
void reverse(char a[], int size);
void add(char a[], char b[], int c[], int size);
int main()

View 2 Replies View RelatedI have a function like this:

void f() {

list contains, in order: A, B and C in any order, D, E
I am thinking it is possible with some clever template and polymorphism combos, but maybe not. As a last resort I know how to make it work by storing static type information in each class, but I'd like to avoid that if possible.

I am getting error at the assertion points when i call to the class as follows:
osgOpenCL::Context *cxt = osgOpenCL::Singleton<osgOpenCL::Context>::getPtr();
I tried commenting assertion statements and then the debugger just exits at the point where getPtr() is called.
What is the efficiency of the two assignments (line 1 and 2), i.e. (function calls, number of copies made, etc), also the Big O notation. I know there are function calls for retrieving the size of each string in order to produce a new buffer for the concatenated string...any difference between line 1 and 2 in terms of efficiency?
String s("Hello");
String t("There");
1. s = s + t;
2. s += t;
I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code:
#include <stdio.h>
#include <string.h>
int main() {
char str[100];
int i = 0;
[Code] ....
Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0;
at the beginning of the code and then made
Code: count = strlen(str);
why wouldn't i have the same result? Is there a way to do it also?
I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main() {
string str = "3 J JD,K";
stringstream ss(str);
[Code] ....
Output of the code is
3 J JD
k
but I want
3
J
JD
K
Also after I split the string is there any way to put the split string into individual string variables.
