C/C++ :: Converting String Of Ints To A Vector Of Ints?
May 8, 2014
I am getting a string from the consle and that all works fine. I'm expecting a string of number, ie 123456.... I store that fine in my string object. I then need to take each individual number, ie 1, and put it in a vector then take the next number, ie 2, and put that in the next element in my vector.
Everything i've found and does eaither takes the entire string and stores it as an int, or takes the ascii representation of the number and stores that. How do I seperate each individual number and store them seperatly. below is a few different variations i've tried that doesn't produce my desired results.
cout<<"Please type the memory memory frames (numbers 0-9) to be used to simulate the input memory "<<endl;
cout<<"Your input: ";
string line="";
cin>>line;
cout<<"
Please wait while your input is processed and validated..."<<endl;
[code].....
the only thing i havn't tried yet is string streams and i don't necessarly like using them. Am i going to have to go that route? will that even work?
EDIT:I forgot to mention that this is being done on linux and then ported to unix.
I have saved the contents of an int vector to a txt file and the numerical data was converted into a c-string. Nov I need to import and read the contents back into my program but I have not been able to convert c-string numerical data back into ints.
The code is supposed to take either an int or a string (and their respective vectors) and insert a given int or string into the vector in ascending order. My code works properly for ints, but it's having a problem with strings.
The order I get with the strings given is
penguin banana great jungle
For some reason comparing penguin to banana/great doesn't give the expected result. The template attached only includes the function and the private vectors needed for the function.
template<class T> class orderedList { public: void insert(const T& item); private: vector<T> list; int total = 0;
I am working on an assignment to create a Complex number calculator. In this assignment I am to ask the user for input to the calculator. We are given a sample run output that looks like this.
Enter operand1: 3 4 operand1: (3, 4) Enter operation : + Enter operand2: 1 2 (3, 4) + (1, 2) = (4, 6)
My question is how would I take from the user: an integer followed by a space followed by another integer and convert that into two seperate accessible int values that I can save as real and imaginary values.
I have some paper work to do about a game I should be able to play with my class mates. We should be able to send and recive a struct concerning about the 'moves' of the pieces at the game. This struct is made of 4 ints, simple as that.
I had a previous paper work to do where I'd have to send ints and that was ok, but now that I have to send a struct I'm failing to do so. This is What I've tried:
//SERVER struct message{ int code; int piece; int x; int y; }send; bytes_sent=write(new_socket,&send,sizeof(message)); cout<<bytes_sent;
So far so good, I see 16 as bytes_sent's value.
On the other hand:
//CLIENT struct message{ int code; int piece; int x; int y; }recive; bytes_recvd=read(my_socket,&recive,sizeof(message)); cout<<bytes_recvd;
I have gotten it to record the date and I can printf it either on the same function, or in the main(). However, one of the requirements I must adhere to is to printf the statement in a brand new function, but when I do that, it just doesn't work. Heres what I mean:
Code:
#include <stdio.h> #define TICKER "LRCX" #define INVESTMENT_AMOUNT "10,000.00" //Prototypes int getdate(int* month1,int* day1,int* year1,int* month2,int* day2,int* year2); float getprice(float* BPrice, float* SPrice); void printdate(int month1, int day1, int year1); }
At first i had my int variables in global scope however i cant do the so im trying to pass my variables from my main to the void functions but cant.....
I am trying to generate some lists of permutations of ints but I can't make std::next_permutation work for me. The problem is I need to include permutations which don't use every number. For example take the array of numbers [1, 2]. I need an algo that will return:
I am trying to figure out the larger 2 out of 3 integers when i call them into a function from main program so far i have . How to write a simple function that will take 3 ints and find the sum of the higher 2?
Code:
int findsum(int a,int b,int c)// will find the highest int and return it to our main program { int max,max2;// this sets our local variable max // next we will find the larger of our first 2 variables if( a>=b)
[Code]....
How to get the second highest number and add it to max...
I'm supposed to create a program that will find the min/max values of two ints, doubles, and chars, It's not completely done but here's what I have so far.
It's giving me an Error 1 error LNK2019: unresolved external symbol "public: __thiscall MinMax<int>::MinMax<int>(int,int)" (??0?$MinMax@H@@QAE@HH@Z) referenced in function _mainC:UsersDerickDesktopCiss243Week3 Assignment2Week3 Assignment2Main.objWeek3 Assignment2

I don't know why the site is adding in extra bits of code like /> in certain areas, it's not there when I paste it in and it's not in my code ....
I have been trying to figure this out for a text based game. Lets say your money is 500. Then you save your game, but when you start the game the starting is 50, so when you load it, you still have 500 money, I tried lots of test, and im having trouble?
I'm able to convert an integer to a vector<unsigned char> and back. However, when I try to use a nearly identical function designed for the long long data type, the last byte or two is broken.
Program code:
long long num = 9223372036854775551LL; cout << "Before: " << num << endl; vector<unsigned char> data = getBytes(num); num = getLongLong(data); cout << "After: " << num << endl;
Code for converting between vector<unsigned char> and long long:
Code: vector<unsigned char> getBytes(long long value) { int bytes = sizeof(value); vector<unsigned char> data(bytes); for (int i = 0; i < bytes; i++) data.at(i) = (unsigned char)( value >> ((bytes-i)*8) );
I have a cpp app that reads in a number of files and writes revised output. The app doesn't seem to be able to open a file with a ' in the file name, such as,
N,N'-dimethylethylenediamine.mol
This is the function that opens the file :
Code: // opens mol file, reads in rows to string vector and returns vector vector<string> get_mol_file(string& filePath) { vector<string> mol_file; string new_mol_line; // create an input stream and open the mol file ifstream read_mol_input; read_mol_input.open( filePath.c_str() );
[Code] ....
The path to the file is passed as a cpp string and the c version is used to open the file. Do I need to handle this as a special case? It is possible that there could be " as well, parenthesis, etc.
I have to convert my netpay which is a float to a string So if I input a value of say, 356.26 it should output "the sum of three hundred fifty-six and 26/100 dollars" . My program function works for the sum of three hundred but after that it spits out garbage.
How will I add the existing content of the text file to the newly inputed date(hoursworked & minsWorked) to compute the total number of hours works. I'm just a beginner in using Visual basic C++.
I'm trying to find a way to accuratley convert a double in the form of a bank account number stored in a file into a string representing the number returned by a file.
BASICALLY, I have to convert netpay (float to string). Theoretically if I have 666.66, my program here should output the sum of "six hundred sixty-six and 66/100 dollars".
i think i need to convert a double to a string, we are working in visual studio doing a program. when i run the calculator i'm not getting the answer i need instead its giving me 0.0 when it should be reading 0.5, here is the code i'm using
{int width; int height; int area; double gop; String ^strWidth; String ^strHeight; String ^strArea; String ^strGop; strWidth=width1->Text;
