C++ :: Function To Build Multiplication Table Of Arbitrary Dimensions - Unexpected Output
Nov 8, 2013
So the latest challenge from jumping into c++ is as following.
Code:
Write a function that builds the multiplication table of arbitrary dimensions This chapter also talks a ton about 2d arrays.
So I've built my program thus far as this.
Code:
#include <iostream>
using namespace std;
int drawTable(int,int);
int main()
[Code] .....
So basically, the idea is that I can use the arrays dimensions as a placeholder, and just multiple them to get that specific spot, so table[0][0] = 0, [0][1] = 0 and so on. However the output actually seems to be randomly generated numbers so I'd like to ask, what am I doing wrong? Am I on the right track? Or have I missed the bus stop completely.
I am currently trying to understand why this example for using an array as an argument in a function has a different result than what the lecture notes say it should be.
So supposedly sum should return with the value 28, but I get 27 no matter what. I also am not very good at reading and understanding what exactly the order of operations for this function are.
Code: #include <iostream> using namespace std;
int sum(const int array[], const int length) { long sum = 0; for (int i = 0; i < length; sum += array[++i]); return sum;
I want to declare a 2D 4*4 array, and fills the array with the multiplication table of an integer x from the user, for example: x*1,x*2,x*3, ....., x*16 and how to pass that array to a function to print the array and to another function that swaps a column with another column chosen by the user.
If a user enters a string of boolean algebra it will ouput the table.
I have input parsing, cycling through the combinations, and outputing working. However once i parse the input I am not sure what to do with it. I have thought of having it write the parsed input to a new file as a function and then use that function, but that seems bad.
How to dynamically create the function, how to implement it.
BTW This is a console function, if that changes anything.
I would like to print a multiplication table, with the dimension n given as input. I attached how the table looks like for n=7.
How do you output the character "-" in that sequence? The first and last numbers have 13 "-" characters before and after them, but the numbers in between have 8 "-" characters.
This program to find the multiplication table, need explanation this step : printf("%d * %d =%d ", n, i, n*i);
#include <stdio.h> int main() { int n, i; printf("Enter an integer to find multiplication table: "); scanf("%d",&n); for(i=1;i<=10;++i) { printf("%d * %d =%d ", n, i, n*i); } return 0;
i need the output to display the product of every whole number from 1-3 in a table format.
this is the code i have so far. i know some brackets are missing but i just pasted the meat of the code. when i run the program i keep getting the number 1 displayed in a straight line going on forever
This is the question; Write a function that builds a two-dimensional multiplication table with arbitrary sizes for the two dimensions.
This is what I have done. I have allowed the user to input whatever size table they want by arbitrarily choosing what value they can input. However I cannot get the board to have blank squares. I thought the char would do it.
Code: #include <iostream> using namespace std; char SQAURE_CHAR = {' '}; const int Board_Size = 14;
Write a program that prints a multiplication table using nested loops. In main ask the user for the smallest column number , the largest column number and the size of the increment. Ask the user for the same information for the row values.
In the example the column values entered are: 5, 15 and 2 and the row values 3, 6 and 1.
Given those numbers you would generate the following table.
Multiplication Table | 5 7 9 11 13 15 ___|___________________________________ | 3 | 15 21 27 33 39 45 4 | 20 28 36 44 52 60 5 | 25 35 45 55 65 75 6 | 30 42 54 66 78 90 Print the 24 values with the grey background. The other numbers show the values to be multiplied.
Code: #include<stdio.h> main() { int a,b,c,d,e,f; int i,j,total; printf("Please enter smallest column number: "); scanf("%i",&a); printf("
[Code] ....
Challenge: As an added challenge try to print out the column headings (5 7 9 11 13 15) and the row headings (3 4 5 6)
#include <stdio.h> #include <stdlib.h> int n; int m; char input[20]; int num; int main() { int num0;
[code]....
I'm supposed to write C program that will generate a 5 X 5 multiplication table starting with the number of the users choice. The program is supposed to operate within a loop and run until the user indicates that they no longer wish to enter any more numbers. I can get the program to run but am wondering what I need to do to get the program to ask for another number and how to make the program stop when the user no longer wants to play. Should I start with "Do you want to enter a number" if yes, run back through loop if no, goodbye?
I need to build an array in a function and return that array. Well, two arrays actually, which means I can't return it in the return statement.
Long term, this function/method is supposed to return two populated buffers for further processing. The buffers/arrays are loaded from a file. So, the size of the array is completely unknown until after the file is read. So, you can't have a fixed size array until the function is almost ready to return.
I'm hardcoding the arrays here for testing purposes, but eventually they will be loaded in from a file. That's the whole purpose of this.
Anyway, I need to pass the arrays that are created in this function/method to the caller. But I can't figure out how to do it. The code "almost" works, except that it's overwriting my array when it returns.
VertexListPointer returns the correct data structure (actually its an array of structures). The problem is that the first time I use the other variables it over rights the array. The pointer still points to the same spot, but VertexBufferDescription is next to the VertexListPointer and so completely overwrites it.
What I "think" I want is to allocate the array in a totally different area of memory. VertexListPointer should be a pointer, not a contiguous block of memory. It should point to the contiguous block of memory elsewhere.
This is where my weak understanding of pointers comes back to bite me in the posterior end.
In the end, I just want to pass back two arrays/buffers to be used by the calling code.
So when you enter the number 99 its supposed to quit the program and it wasnt so i fixed that then i noticed that if you don't hit the green its supposed to loop back to a certain point but it was going to far back so i put a goto statement in and now it wont output my data table.
I have a large hash table, where each index has a container that has a doubly linked list. Things work up until releasing the memory. Each record is created with malloc, and each record->data is also created with malloc and the associated string is copied in using strcpy(). The table itself is released in another part of the program and doesn't produce and error.

How to interpret valgrind. Error resolved on a small problem. Now running into issues on large (>10000 words to check) problems. It appears the virtual machine just can't keep up for some reason. Running the code on my local computer produces no errors, memory usage is minuscule, and profile tools don't report any issues.
Have everything working fine as far as input and functions.. I am supposed to output the information as a table. I started to write a void function in order to complete this task. I know how to output the information if i were to have an array for the months, but how to display the months when I am using a switch statement.
#include <iostream> #include <cstring> #include <iomanip> /* author: John Pierce Description: program reads in averages, then prompts user for current month. The program then continues to prompt the user for the rain fall amounts for the previous year. */ using namespace std; void printMonth(int month);
Write a program to create an output file containing a customized loan amortization table. Your program will prompt the user to enter the amount borrowed (the principal), the annual interest rate, and the number of payments (n). The payment must be rounded to the nearest cent. After the payment has been rounded to the nearest cent, the program will write to the output file n lines showing how the debt is paid off.
Code:
#include <stdio.h> #include <math.h> int main (void) {
void Arrival_MainThread::Body () { t1 = new boost::thread((Arrive_Fctor()), 2); t2 = new boost::thread((Arrive_Fctor()), 10000); t3 = new boost::thread((Arrive_Fctor()), 3000);
Code: class Arrive_Fctor { public: void operator()(int mean) { m_Arrivals = new Arrivals(mean); m_Arrivals->Activate(); #ifndef NO_RESOURCE
[code].....
The order of arrivals always appear as 3,2,1 it can't be 1,2,3 or 3,1,2 or something like that?
The body method is called when m_Arrival->Activate() is executed, and it is running as an independent thread.
