It seem to store the entire line in userID including the ":". I want to ignore the ":"'s and store everything in between in respective varibles in the order specified above.
So first string in userID, then ignore the :, then second string in name, and ignore the next :, and so forth.

I am working on a text based RPG. As with most RPGs the character has attributes that grant modifiers. Lets take strength for instance. Suppose the character can have a strength score that ranges from 1 to 10. Based on strength the modifiers could be like the following:
Strength = 1 grants +1 to hit and +1 damage Strength = 2 grants +1 to hit and +2 damage Strength = 3 grants +2 to hit and +3 damage
I want to set these values at design time and be able to retrieve the modifiers based on the strength value from multiple places in my program.
What is the best method of designing this. I looked around online and saw references to Lists with Tuples and Dictionaries with Tuples but these did not seem to be a very efficient way of handling the scenario above.
So I have to read from a file, and store the information in separate variables. My problem is that for some of the information I need multiple words, and for others I don't, so I cant simply store 1 word into a variable and store the next in another in so on. To demonstrate what I mean let me give an example.
Dog Cat Blue Bird Snake White Horse
I am able to store "Dog","Cat","Blue","Bird"...etc in variables but I don't know how to make it so I can store "Dog" in one variable, "Cat" in a second variable. and "Blue Bird" in a third variable. "Snake" would be the 4th and "White Horse" would be the fifth. How can I read a file and manipulate the pointer to grab what I need?
I can't get my code to compile, i need to read in lines from a file and store them in variables. Then i have to construct instances of my class for how many lines there are in the file and take those variables into them.
I'm getting this error :
"a2.cpp:40: error: cannot convert `Employee' to `Employee*' in assignment"
#include<iostream> #include<string> #include<fstream> void displayInfo(); using namespace std; class Employee{
I want to store the address of a customer (with spaces) in a char variable (say cadd). First I tried to use "cin", as we know it reads until it sees any whitespace. So it reads only first word before a white space. So, I used "getline()" function, it will work. But when I used it, It did'nt wait for the I/P (it skipped it).
So I have to write a code for my C++ class, and I am having a problem trying to figure out how to get my code to read multiple int values. This is what my code should look like
Enter two times in military format (e.g., 1730 1520): 1730 1520 [1520<1730] Enter two times in military format (e.g., 1730 1520): 1520 1730 [1520<1730] Enter two times in military format (e.g., 1730 1520): 1730 1730 [1730==1730] Enter two times in military format (e.g., 1730 1520): 1760 1520 1760: [INVALID TIME 1] Enter two times in military format (e.g., 1730 1520): twelve 2 [INVALID NUMERIC INPUT]
This is a small program that reads a line from the screen, takes the ASCII values from the entered text, and edits it. Next, the ASCII values are reinterpreted (am i misspelling?) as text, and displayed. However, my final output has (allways?) at least 7 characters, even if you enter only one. I'm also trying to accomplish, that the part of the string which isn't filled, will be printed empty. In spaces.
compiled with -std=c99.
Code: #include <stdio.h> int main(){ int maxsize; printf("How long is your message?
I'm using fgets which will read a single line at a time, but unlike fgets I don't want it to return the new line char ( ) ?I want to be able to use printf to display the lines next to each other.
I need to read a text file which has various lines containing integers. I need to write those integers separately in a vector. Example, the first line of the text file contains 3 9 8 7 6 so vector[4]=3, vector[3]=9, vector[2]=8 and so on. Next read the second line 4 1 2 3 4 5 and write to another vector vector[5]=4, vector[4]=1...
I tried the code below but it will write from the second line, the whole line in one vector index.
int str; // Temp string to cout << "Read from a file!" << endl; ifstream fin("functions.txt"); // Open it up! string line; // read line count from file; assuming it's the first line getline( fin, line );
I have an external file with one column of data. If I have a counter value let say counter =1, and counter++ and so on. How I can write such a c++ code that if the value of counter and value from the external file are same then generate an action let say cout both values i.e. value of counter and value from external file.
for more information, here is an example:
data in file(in one column): 2 6 8 9 10... value of counter : 1 2 3 4 5 6 7 8 9...
then cout values only if value of counter and value from the file is same.
Here is my code so far, but it does not seem to work;
#include<iostream> #include<fstream> using namespace std; int main() { const int SIZE = 10; //Size declaration of array int hours[SIZE]; //Array declaration
I am reading my file (20GB) line by line using boost like this
PHP Code:
boost::interprocess::file_mapping* fm = new boost::interprocess::file_mapping("E:Mountain.7z", boost::interprocess::read_only); boost::interprocess::mapped_region* mr = new boost::interprocess::mapped_region(*fm, boost::interprocess::read_only);
I'm struggling with the whole stack/heap thing. I totally see the need to create objects on the free store to outlive functions, however, I don't see the purpose of "new" when working with classes.
Code: class Person{ public: Person(std::string strName, int number); ~Person(void);
Resource r;
[Code] .....
Now, what is the difference? Why would I need to create a Resource on the free store? Both variables named r live until the destructor runs, right?
I need to store the last 3 deposit that I have in my deposit. I have few option but i dont which would be easy
1.Store all deposit to the text file (store always in a new line), and display the last three deposit from the text file.
dep 1 - 60 dep 2 - 40 dep 3 - 100 print 100 dep 4 - 50 print 50 dep 5 - 50 print 50
2. I think this option is more difficult, when it reach deposit 4, to get rid deposit 1
So when i make a deposit 4, the deposit 1 get's ride dep 2 - 50 dep 3 - 100 dep 4 - 70
Right now i can only display one deposit (last one), then i close the program and run again and i make another deposit it overwrites a new deposit.
My code. To show sure my deposit that has been made. double depSave () { int option; float dep1,dep2,dep3;// Declare your variables dep1 = dep2 = dep3 = 0; // Set them all to 0
system ("cls"); string path = "deposit.txt"; // Storing your filename in a string
[Code] ....
Where is says "save deposit" in comment that where it saves to the deposit text file, that going to be output to the depSave function.
How to input two variables in the same line? Like when i type 12 and press enter, 1 must be assigned to a, and 2 must be assigned to b. I want it to be entered on the same line, and press enter only once. How do i do that?
write a c++ program that reads an unknown number of integer values and then print count, sum and average of odd values, even values, positive values, negative values!!
Are the objects in both vectors the same instance of the object? Like if I called vectorOne[0].setValue(somethingDifferent); would the value be changed for the object in both vectorOne and vectorTwo? If not, how do I make sure that I only have one instance of the object I'm trying to store in multiple vectors?
am trying to create a program that asks the user personal questions.
std::vector<std::string> name, age, favsinger; std::cout << "Hello, what is your Name Age Favorite_Singer? "; std::cin << name; //i want to store the user's info along with the sibling's
