I need to input values for two arrays and then add the two with all of it being print visible. I have this so far but can not figure out how to add the two arrays.
#include <iostream>
using namespace std;
int main ()
{
{
int const ROWS = 3;
int const COLUMNS = 3;
int square[ROWS][COLUMNS];

You will have two file streams: an input file stream for the file to be normalized and an output file stream that contains the normalized file. You should issue an error message and exit the program if either file cannot be opened. Your program should prompt the user for the filename of the file to be normalized (the input file). The output filename should be the input filename with ".normal" added to it. For example, if the input file is "data.txt", the output file name will be "data.txt.normal".
Be careful to not leave an extra blank line at the end of your output file.
My question here is how do I rename the file that the user entered to have a ".normal" at the end of it? I was thinking along the lines of having to string names and changing the second string's name and use that as the output file. any examples cause I didn't exactly get that to work.

I need to add thevArr[I] and vArr1[I] and store in vArr2[I] but I cant figure out how to drop the value or replace with a 0 if vArr is bigger than vArr1. IE: 1st number: 123 2nd number: 4567
Ill get something like this:
1 2 3
4 5 6 7
5 7 9 -827349
I'd like to start out by adding an array to a C++ class. I'd like to be able to reference the array using a class object that I create, for example:
Class is Stone.
Stone Bob is an instance of "stone" that I name "Bob".
"Bob.array[1] = "granite";" tells the compiler that the second element in the array (with the first being the zeroth element) is a string containing "granite".
I'll eventually want to extend this to an n x m matrix within the "stone" class that can be referenced as: Bob.matrix[1][3]="lignite";
I tried to make this work using a text again and again last night to no avail. My code is below.
NOTE: Since I am dynamically allocating memory space, I'd like to avoid memory leaks when using this class with dynamically allocated arrays and matrices. Not sure how to do this. Also need some insight into "destructor", and why my simple version reduced to a comment below doesn't seem to please the compiler.

I am currently working on a program that uses a class to store integer arrays. I have most of the code done, but I am having trouble on the main.cpp part of my program. The program should display this:
OBJ 1:
2 3 4
OBJ 2:
1 4 -2
Addition:
OBJ 1 =
3 7 6
Subtraction:
OBJ 1 = 1 -1 6

I'm writing a program with two classes, one that contains a card's rank and suit and the other contains pile of these cards. I'm having trouble when it comes to adding a pile to another pile...here's what I have so far:
class Card //Card class declaration
{
private:
int rank; //invoking rank
char suit; //invoking suit
public:
void setCard(int r,char s); //determines card suit/rank
[Code] ....
I understand that I'm calling my pile arrays incorrectly, but I'm not sure why.
I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)
Code:
int _tmain(int argc, _TCHAR* argv[]) {
int comm = 10;

Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?

#include<stdio.h>

int arr[4][5];
for (int(&row)[5] : arr){
for (int &column : row){
} }
Why do we name it row instead column?
int arr[row][column]
Wouldn't this be like
int arr[4][5];
for (int(&column)[5] : arr){
for (int &row: column){
}
It just seems funny to me because we use row[5] which should be 4 if we meant row? Or did I read it wrong in C++ prime !?
I'm trying to write a function that takes a 32bit address and a data to store at this address.
I'm wanting to take the 32 bit memory address eg 0x12345678 and split it
into 4 x 2 bytes
12, 34, 56, 78
then each of the 4 entries is at most a 256 entry array.eg
FF, FF, FF, FF
So in this example, 0x12 points to 0x34 in the second array, which points to 0x56 in the third array, which finally points to 0x78 in the last array. This last array holds the actual data.
After successfully doing 0x12345678, say I might get a read for 0x1234AABB. So, the first and second pointers already exist, but I then have to create and write to dynamically created arrays.
The arrays need to have all entries set to NULL so that i know whether to follow the pointers to overwrite a previously entered value or create new arrays and pointers.
It all looks good and simple in the pseudo code I've written up but I'm having trouble coding it. I'm currently trying to deal with the first entry case, ie all array elements are NULL, but I'm getting confused with the pointers and creation of new arrays.
void cpu::store(unsigned int mem_add,unsigned int mem_val) {
int first = (mem_address&4278190080)>>24;
int second = (mem_address&16711680)>>16;
int third = (mem_address&65280)>>8;
int fourth= (mem_address&255);

(Write a program that provides the option of tallying up the results of a poll with 3 possible values. The first input to the program is the poll question; the next three inputs are the possible answers. The first answer is indicated by 1, the second by 2, the third by 3. The answers are tallied until a 0 is entered. The program should then show the results of the poll—try making a bar graph that shows the results properly scaled to fit on your screen no matter how many results were entered.)

I am new to c and I have come across a problem when adding other functions to a programme and printing the values. The question I am attempting to solve is :
The following function computes ex by summing the Taylor series expansion to n terms. Write a program to print a table of ex using both this function and the exp() function from the math.h library, for x = 0 to 1 in steps of 0.1. The program should ask the user what value of n to use.
double taylor(double x, int n) {
int i;
double sum = 1.0;
double term = 1.0;
for (i=1; i<=n; i++) {
/*Or we could have written: */
term = term * x / i; /* term *= x / i; */
sum = sum + term; /* sum += term; */
}
return sum;
}
My code is
Code:
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
/*Taylor series for e*/
[code]....
code prints out the values for exp, but it gets stuck in the Taylor function and I'm not sure how to solve it.
So here is what i need i need a way i can add 3 variables one after the other example:
int a = 1;
int b = 2;
int c = 3;
//Here comes my problem
int d = a + b + c;
When I write it like thet d = 6 ,
but I need it to be 123,
int sum=82;
for(int i; i < sum.length; i++)
{
final=sum[i]+final;
}
I need getting the sum and adding the numbers together. for example 82 would be 8+2. I keep getting an error on this piece of code....

Currently in development of a cookie clicker clone (for fun)
I am stuck at the idea of the "Cookies Per Second" thing.
Is there a way to implement a per second adder thing that doesnt actually effect the game play (eg even though the player may not be pressing C every second a cookie (or more) will be added, or if they can press C more than once a second, every second a cookie will be added... If you get what I mean).

This is my code without malloc. I need to change the array size so there is no max size for each matrix. I must dynamically allocate space for all arrays used. So I need to use malloc to create my arrays. So I cant use int A[rows][cols].

int first[100][100], second[100][100], sum[100][100];// Matrices variables

Im having a hard time understanding/using malloc. Should first, second, and sum be single pointers or double? How do I scan the matrix correctly? And how do I add them properly? Do I have to change my for loops?

I am currently working on a program and Originally I was to create a bash program to extra information from youtube and create a table of users, views, titles, duration, etc. (I sent each to a txt file)..Then I was to create a C program to use the extracted information. In this case Users and read in the conents of user.txt and construct a linked list to hold the information. Then print from the Linked list.I managed to do that,
Code:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#define LINE_LENGTH 100
void build_a_lst(), print_a_line(), print_lst();
void insert_at_end();
}

What I have to do now is start reading in The other files and construct a table. And radix sort it by views. But to get to the radix sort part I get stuck on reading in all the files correctly and having the linked list hold them. I keep getting seg faults when I change my code.

I am trying to convert a string Input by user into an unsigned byte array.The data would be in hex form like :- "AE 1F 2C".

View 3 Replies View RelatedI was trying to solve a problem that required to add one hundred 50 digit numbers. Since there is no way to hold such a huge number. I read that storing them in strings is the way to go. I was caught midway while trying to do the same.

And the text file is this. Code: 123465789 321654987 This isn't the exact huge number, but I wanted to try it out with lower number before trying out with the original huge ones.I am trying to store the numbers in a two-dimensional array. However when I and try to pass the single number as an parameter to the AddTwoStrings() method, It actually passes the entire number as such.
When I pass string[0],string[1] it should pass the first and second number from the files as the two numbers instead of the whole number as such.The function AddTwoStrings() doesn't do anything as of now, I encountered this error when I was testing the code till this part.
