Oct 31, 2014I am trying to get a list of queries to work right now. I have it so that the user will input 1 of 5 things to compare twin primes in a list. I am just trying to get the queries working fully before actually determining the twin primes that need to be output. The console input will be something like "<= 61" and will display all twin primes from 3 to 61, inclusive.
Well, I thought I had it 100%... Then I realized I have a problem, though. So, I'm reading the string in until a space so I can read in the number after that. So that works fine, but then I also want the "all" and "random" console inputs to work, but they won't unless I put a space after them, which is what I'm trying to avoid...
So, I tried just simply asking for another console input after all of my if statements for the string compare after the first console input. That obviously doesn't work either, though, because it still only wants the first "getline" where it reads until the whitespace.
How to be able to do both on the same console input... The relevant code is posted below:
cout << endl << "What do you want to know about your list of twin primes?" << endl;
string qprompt1;
string qprompt2;
getline(cin, qprompt1, ' ');
string comp1 = ">";
string comp2 = ">=";

C++ :: Unable To Compare A String With A Char Pointer
Jan 28, 2013Ok, I'm having a few problems with strings, mostly string functions saying they're not able to compare a string with a char pointer.

My goal is to take in a command and store it in a string. Different commands have different amounts of information I need. One command is "new flight <flightnumber> <seats available>". First, I try to understand which command is being asked, using the first character to decide. Once I can assume which command is being attempted, I try to separate the string into smaller strings (words) using strtok. I then compare the words that should be constant (new and flight), to make sure the command is syntactically correct (which I use strcmp for). Then I'll go on to create a new flight, which is a class that takes in a char * and integer (which is why I need to convert a char * to integer).
C++ :: Compare String Vector Against Enumerated Type?

C++ :: How To Test A Compare Function With Parameter That Is Blank String
Feb 18, 2013Modify your code by adding your own tests to see if your functions work right. Include at least 6 separate tests, of your choosing.
For example, test the compare function with the first parameter as a blank string -- then with the 2nd as a blank -- then both. Test compare with the first string shorter than the second -- then the other way around. Test your copy function with long strings.
I am struggling with how to use the compare function with a parameter as a blank string. I tried leaving the first parameter blank but doing ("",text) but I don't think that is the correct way of doing this.
#include <cstring>
#include <iostream>
using std::cin;
using std::cout;
using std::endl;
int myStrLen(const char[]); // return length of null-terminated string stored in char array

C :: Bulls And Cows Program - Compare Table With Input String
Dec 14, 2013I'm having a small problem on comparing a table i coded with a string that I want to input. I'm actually building a Bulls and Cows program and this is part of my assignment. What i want to do is to input a string and from the table get the results compared to the string i inputted.
Few words about the Bulls and Cows program.
The game involves two players, a coder and a cracker. The coder (either a person or a computer) chooses the four-digit number with all different digits and keeps it secret. The cracker tries to guess the secret number. After a guess, the coder gives you information about number of digits which were correctly guessed but in the wrong place (they are called 'cows') and how many are both the right digit and in the correct place (they are called 'bulls').
For example, if the coder chooses the secret number 0419 and the cracker guesses 6039, then the coder scores this as 1 cow, since 0 is a digit in the secret number that's in the wrong place, and 1 bull (9 is in the right place.)
what i want to do is when i input a string it scans the whole table of possibilities and gives me the results based on the string. so each row of my table is (let's say the secret code) and based on the given string(the guess) it gives me the result. Here's my table code:
Code:
void initialize(int poss[1296][4])
{
int i=0;
int j, k=0;
int m;

C/C++ :: Enter String Into String Array Via Cin Or Getline
Mar 29, 2014Ok so I searched this site, and google string arrays, but I couldn't find anything on how to create an array to accept string input. In other words the strings are unknown, until the user inputs them..
so code would say input a name..user enters Tom, and its inserted into the array.. and if another name is entered ..lets say Lisa..Lisa is added to the array..so now in the array we have tom and Lisa..
Everything I read only shows the array already having the strings declared...
string n;
string name[n]={};

C# :: Making String Equal Many Different Values Then Compare Those Values

Here I would like to see if my speech had ended with any of the values i would have stored in the string "numbers". If it did, I would like to just take the value and add it to a new string called whatever

I have tried this a million different ways and I cant get it to work. I'm not even sure how I would go about storing tons of different numbers in one string, or if that's even possible.
Visual C++ :: Retrieving Size Of Each String In Order To Produce A New Buffer For Concatenated String

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?

C :: Program Where User Inputs A String And Prints Out Length Of String
Jan 29, 2014I 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?

string str = "3 J JD,K";

C/C++ :: Comparing Input String To Type String Vector
May 29, 2014I 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;
}
