Visual C++ :: Assignment Is Recursive Call And Placing Strings In Link List Notes?
Oct 30, 2013You need to write a permute class that will take first and second strings to rearrange letters in first, followed by second. For example, if the first is “CAT” string and second is “MAN” string, then the program would print the strings TACMAN, ATCMAN, CTAMAN, TCAMAN, ACTMAN, and CATMAN. The first and second strings can be any length of string or a null.
The permute class uses a Note class as link list note to link all letters arrangement. The permute class has Note pointers, firstNote and lastNote, to point to the beginning and ending Notes of the link list as private data members. There are three other private data members (total, firstString and secondString) to store the total possible number of arrangements and strings pass into the class.
Write a driver to test the permute class to pass in any two strings of any sizes.
Other than mention in the following, you can add more classes, functions, and private data members to this program.
Note class:The Note class needs to have two private data members and a constructor. The two private data members are data and p pointer. The data’s data type is string and p pointer is Note. The Note class constructor has two parameters, one is string and the other is Note pointer.
Permute class:The Permute class has five private data members (*firstNote, *lastNote, total, firstString and secondString). The firstNote and lastNote pointers are point to Note. The total has integer data type. The firstString and secondString have string data type.
There should have at least three public member functions, Permute, permutation and print. The Permute function is the constructor which takes strings to initialize the private data members. The permutation function does the recursive call to arrange the strings and setup the link list. The print function will print out the private data member information.
Driver file:The driver file should declare a Permute eight elements pointer array. Instantiate eight Permute object with the following eight set of data and assign the object to the pointer array. Use a repetition to call the object’s print function to print out the private data member information. If the total of the permute private data member is less than 100 then print out the permutated letters four in a row, otherwise print out 9 in a row.
first = "", second="",
first = "", second ="CATMAN",
first = "C", second ="ATMAN",
first = "CA", second ="TMAN",
first = "CAT", second ="MAN",
first = "CATM", second ="AN",
first = "CATMA", second ="N",
first 1 = "CATMAN", second ="";

C++ :: Adding Strings Of Integers
Jan 29, 2013I'm trying to write an algorithm for a larger project that will take two strings which are both large integers (only using 10 digit numbers for the sake of this demo) and add them together to produce a final string that accurately represents the sum of the two original strings. I realize there are potentially better ways to have gone about this from the beginning but I am supposed to specifically use strings of large integers as opposed to a long integer.
My thinking was to take the two original strings, reverse them so their ones position, tens position, and so on all line up properly for adding. Then one position at a time, convert the characters from the strings to single integers and add them together and then use that sum as the ones position or otherwise for the final string, which once completed will also be reversed back to the correct order of characters.
Where I'm running into trouble I think is in preparing for the event in which the two integers from the corresponding positions in their strings add to a sum greater than 9, and I would then have carry over some remainder to the next position. For example, if I had 7 and 5 in my ones positions that would add to 12, so I would keep the 2 and add 1 to the tens position once it looped back around for the tens position operation.
I'm not getting results that are in any way accurate and after spending a large amount of time stumbling over myself trying to rectify my algorithm, I am not sure what I need to do to fix this.

C/C++ :: Parsing Integers Values From Strings
Sep 30, 2014So I have this assignment to read a file in, malloc some arrays, run it through a perceptron and to display the final weights. I have the majority of it already written but this is only my third program in C and I'm more familiar with Java and Python than C.
The problem I'm having is when I read in command line arguments, I can't seem to parse integer values from the strings in argv[i] by using atoi().
I've included the piece of code where I'm trying to 'parse.' I understand atoi convers ascii to integer, but I don't understand if it just gives you the ascii code or the number that it actually represents. I attempt to use atoi on lines 33-35
The input arguments in the command line are:
bob in.csv 100 5 10
int main(int args, char* argv[]){
int ** ra; // array of array of pointers
FILE *ifp; // file pointer
char cc; // char var for reading input from file
int i = 0; // counter

C++ :: Getline With Integers / Double / Strings And Delimiters?

C++ :: Mapping Strings To Integers - How To Print String Zero
Dec 12, 2013I'm very very new to maps and am really just trying to hash them out by myself.
If you're mapping strings to integers:
map <string, int> myMap;
myMap[ "zero" ] = 0;
myMap[ "one" ] = 1;
How do I print the string "zero", for instance, from myMap?
cout << myMap.at(0) << endl;
doesn't work. Nor does:
cout << static_cast<string>( myMap.at(0) ) << endl;
I need access to the string using the int and the int using the string. Or just direct access to one or the other. . . It's just confusing that they're technically mapped to one another but I can't really access either of them.

View 8 Replies View RelatedC :: Reading And Printing In A Specific Format Strings Of Characters And Integers
Feb 23, 2015I have been skimming and searching but dont know how to word the search just right to find what I need to know. I have written simple stuff with the support of tutorials like weight conversion or loops counting up to a set number. Nothing amazing. The other day I found out how to input and print a string rather than a single text character which i though was bad ass. I even got it to read multiple strings on a single line and found a way to read multiple lines. I can even format it to read both integers and characters on the same line as long as I know the predefined format.
On to my question... How do I read multiple lines with both carecters and integers. for instance:
nissan 1996
toyota 1998
or more comples like
nissan gtr 1996
toyota markii 1998
I want to use
int year;
char make[10]; maybe need to use char make[10][10]; for an array i would guess.
char model[10]; optional for the extra data
but reproduce what i read in a different order. say...
1996 nissan
1998 toyota
vice the original format.
this is what I have tried.
Code: scanf("%s %s", &make,&year);
//The way I seen to read multiple lines was on here
scanf("%[^/t]", %make);
But this wont let me separate the two into two differnet definded data types. Let alone use printf to display them in reverse order.
C++ :: Reading From Console Multiple Strings Of Unknown Length In Combination With Integers
Oct 10, 2014I want to read a string of unknown length from stdin. I tried to follow the approach from this link.
[URL]....
My code is like this:
Code:
#include <iostream>
#include <string>
using namespace std;
int n;
cin >> n;
cout << "The value of n is " << n << endl;
string str;
getline(cin, str);
cout << "The entereed string is " << str << endl;
What I have noticed is that if I take integer input from cin (cin >> n in the above code before getline, the control does not stop on getline to take str as input from the console. If I don't do (cin >> n) before getline then the control stops on getline and takes the string as input.
What is the best way to read from console multiple strings of unknown length in combination with the integers?
