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,
Instead of using:
Code:
x=x+k
y=y+k
z=z+k
Is there a more elegant method of adding the same constant to many variables?
Something like: Code: (x, y, z) = (x, y, z) + k ??
I tried to add 2 or more strings together but failed.
eg I would like to add "KK" & "LL" together by adding but it couldn't work.
string string_B = "KK";
string string_C = "LL";
string_A = string_B + string_C;
Every time I run if(color=="1") it's supposed to add 1 to redTotal. However, every time I run if(color=="1") if get 1 for redTotal every time.
(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.
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....
How would one add each value from an array? I'm working from a string but I was wondering if there was a way to loop through the string and add each value. This is what I have so far:

std::string numbers;
int sum;

I have the following code in sourceFile.cpp. functionA() is first called and inserted entires for key1, key2 and key3. Then functionB() gets called to use the vectors for the 3 keys. I want to free all memory after exiting functionC(). Among the three ways to put an entry into the map for the 3 keys, which is correct / better?
Class ClassA { ... }
ClassA *key1 = new ClassA();
ClassA *key2 = new ClassA();
ClassA *key3 = new ClassA();

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].

/* This program asks the user for 2 matrices called A and B, as integers, and displays their sum, C. The max dimension of each matrix is 100. */
#include<stdio.h>

int m, n, i, j;// Variables
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'd like to add a 'command' to my C program. For example if someone types 'get out' it closes the shell and quits. I want the 'get out' command to work like 'exit'. How do I write a code like this

if (entry = "get out")

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". I am thinking of using strtok to split the string into be " ". and then cast to (unsigned char *) . But for that I''ll have to prefix every element with 0X Is there any convenient way and elegant way to do this?

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.

I'd like to use the Big Integer Library [URL], but I have issues to use it. I'm using Xcode as compiler and I don't know how to include the library in my project files. When I drag all the files in the project directory and write the statement #include <BigInteger.hh> on the top of the declaration of the main function, even whiteout any other code, I get lots of build error on the .hh and .cc file.

I have a basic question regarding 2d vectors. The following code makes a 2d vector and fills it with a matrix of integers. The vector tempVector3 gets added as a new row to the matrix. But what if I wanted to add the tempVector3 as a new column instead. How would this be done in the simplest way?

I am writing a program to list the 8 planets, then you select which planet you want. it gives you the mass of the planet, the radius, then you use the mass and radius of the planet to find the surface area (sphere formula) and the density of the planet. Along with those options, you have to add and delete a planet from the list and then sort them alphabetically. All i am having trouble with is the adding and deleting part. The code the adding and deleting from the list would go in cases 9 and 10.

View 9 Replies View RelatedCalculate the reversed numbers from the input. Reversed number is a number written in arabic numerals but the order of digits is reversed (e.g. 543 reversed would be 345). You need to add two reversed numbers and output their reversed sum. Of course, the result is not unique because any particular number is a reversed form of several numbers (e.g. 21 could be 12, 120 or 1200 before reversing). Thus you must assume that no zeros were lost by reversing (e.g. assume that the original number was 12).
Input
The input consists of N cases (equal to about 10000). The first line of the input contains only positive integer N. Then follow the cases. Each case consists of exactly one line with two positive integers separated by space. These are the numbers you are to reverse and add together.
Output
For each case, print exactly one line containing only one integer - the reversed sum of two reversed numbers (Get the sum of the 2 integers that have been reverses, then reverse that sum also). Omit any leading zeros in the output.

I'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.
