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.
So I'm supposed to write something that will output a multiplication table from two user input integers between 2 and 10.
For example it should display like this is the user inputs 4 and 5
1 2 3 4 5
2 4 6 8 10
3 6 9 12 15
4 8 12 16 20
I was hinted to used two for loops and this is what I have thus far, what I can't figure out is how to display it like the example.
#include <iostream>
using namespace std;
int main() {
int num1;
int num2;
cout << "Enter two numbers between 2 and 10." << endl;

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.

Remember using "Functions" e.g Multiplication(int x)
{ }
int main{
then call the function}
I have to build a multiplication table in c++ and Im close but it still isnt formatted properly...
// multiplication table

I wanted to make a multiplication table.
Here's the code:
#include<iostream>
#include<conio.h>
using namespace std;
void initArray(int arg1[50][50], int r, int c) {
int val=1;
for(int row=0; row<r; row++) {
[code]....
I want the output to be like this:
1 2 3
2 4 6
3 6 9
If the user inputs 3 rows and 3 columns.
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
int multiply1 = 1;
int multiply2 = 1;
while(num1<=3)
{ // num1*num2;
//num1 = 0;
while(num2<=3)
{ Console.WriteLine(multiply1*multiply2);
if(num1>=3)
{ Console.Write();
}
}
num1++;
}
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("

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;

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?
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'm trying to write a program which prints a table of ASCII chars, I'm not really done with my thoughts on it but I already

Here's my code so far:
# include <iostream>
using namespace std;
int main() {
char asciiTable = new char[8][16];
int nextSign = 0;

I am unable to input the correct form for matrices multiplication. I have an exam tomorrow in which I need to use this.

I'm having trouble printing the text in between separators like commas, periods, and at signs. I'm following Jumping into C++ Chapter 19 Practice Problem 2.

usingnamespacestd;
int findNeedle (char separator, string inputLine) {
int needleAppearences = 0;

I'm having a small problem on comparing a table i coded with a string that I want to input. I'm actually building a Bulls and Cows program and this is part of my assignment. What i want to do is to input a string and from the table get the results compared to the string i inputted.
Few words about the Bulls and Cows program.
The game involves two players, a coder and a cracker. The coder (either a person or a computer) chooses the four-digit number with all different digits and keeps it secret. The cracker tries to guess the secret number. After a guess, the coder gives you information about number of digits which were correctly guessed but in the wrong place (they are called 'cows') and how many are both the right digit and in the correct place (they are called 'bulls').
For example, if the coder chooses the secret number 0419 and the cracker guesses 6039, then the coder scores this as 1 cow, since 0 is a digit in the secret number that's in the wrong place, and 1 bull (9 is in the right place.)
what i want to do is when i input a string it scans the whole table of possibilities and gives me the results based on the string. so each row of my table is (let's say the secret code) and based on the given string(the guess) it gives me the result. Here's my table code:
Code:
void initialize(int poss[1296][4])
{
int i=0;
int j, k=0;
int m;

But the square needs to be hollow like this. So if the user enters 5 then the following square will be shown.

I am having an issue with my sort function. This is one part of the Hash table program. The main issue is that I am trying to sort the pointer table after all of the values have been entered. The ptr_sort function is not a class function and so I am therefore unable to use the class variables psize and pTable. Is there another way I should be trying this? it is a Vector should I use the sort() function from the vector class in STL?

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 have written an SQL statement that would:
1) Count the number of rows in the table booking that are open and where the booking.postcode is "MK",
2) Take a note of the plot (in booking.plot_id), and then update the table plot.jobs with the value count.
For example running the SQL query when booking table has the following rows:
Would see the following highlighted values in plot.jobs being updated to 1:
I managed to resolve it with this code so far (note I am using Connector/Net):
public void RefreshPlot(){
string query =
"SELECT Count(*) AS count, plot_id FROM booking WHERE postcode='MK' AND status='open' GROUP BY plot_id";
var cmd = new MySqlCommand(query, _connection);
var da = new MySqlDataAdapter(cmd);
var dtCounts = new DataTable();
da.Fill(dtCounts);
[code]....
Currently, my code only checks for existing rows in the booking table and updates the plot table. However if the row gets deleted in the booking, then the changes are not reflected in the plot table.
Example: If we delete the row with plot.id=1 and plot.plot_id=4, then booking.plot_id should go back to being 0, if it was initially 1. At the moment, it doesn't. How would I update my SQL statement to better reflect this? In a sense, it should check for "non-existent" rows, i.e. the impact that the row plot.plot_id=4 & plot.id=1 has on booking.plot_id when deleted?
