I'm writing a program to display a histogram of 1000 Gaussian distributed numbers. I've generated the numbers using rand and now need to transform them. I have found the following formula to use
f(x) = exp(-x^2 / (2*sigma^2)) / sqrt(2*pi*sigma)
And I am unsure how to implement this into a function.
Create a program that will display all the composite numbers from 0 to 1000 and has a maximum column of 5 . A composite number is a positive integer that has at least one positive divisor other than one or itself. In other words a composite number is any positive integer greater than one that is not a prime number.
SAMPLE OUTPUT:
4 6 8 9 10
12 14 15 16 18
20 21 22 24 25
26 27 28 30 32
....and so on.

Sum up all the numbers between start and end. Lastly compare this sum to 1000.
--so i got the first part, but how to compare the sum to 1000.
I am doing my assignment that will calculate total tax amount per day and per week and finally sum those up.
One of the requirement is to filter out any number in the array that is less than 1000 to be assigned a value of zero instead of the stored value so as not to add it in the calculation. How to fulfill this requirement.
Write a function that generates 1000 normally distributed (Gaussian Probability Distribution) random numbers. Range should be between -3 and +3. Numbers should be double floating point.
There's more to it than that, but I've got it from there.
I am writing a piece of code that requires me to display the last 1000 lines from a multiple text files (log files). FYI, I am running on Linux and using g++.
I have a log file from which - if it contains more than 1000 lines, I need to display the last 1000 lines. However, the log file could get rotated. So, in case where the current log file contains less than 1000 lines, I have to go to older log file and display the remaining. For e.g., if log got rotated and new log file contains 20 lines, I have to display the 980 lines from old log file + 20 from current log files.
What is the best way to do this? Even an outline algorithm will work.
I have to make program which can generate a lot of random numbers and than prepare histogram with each number. Histogram must look that:
0 ( 50):*****************************************
1 ( 59):********************************************** ***
2 ( 42):***********************************
3 ( 49):****************************************
4 ( 41):**********************************
5 ( 53):********************************************
6 ( 60):********************************************** ****
7 ( 47):***************************************
8 ( 54):*********************************************
9 ( 45):*************************************
Given a random number generator to generate a number between [0,N), how to prove this number is uniform distributed.

I need to construct Truncated Gaussian distribution in the range of (5-20 microns), specifyed by initial standard deviation.
Particularly i need input which comprises of minimum value(5 microns), maximum value(20 microns) and standard deviation of (5,10,20 etc..). In this regard i tried with Box-Muller but it doesn't fulfuil the goal.
i want to to apply a validation for an field which is Vehicle number in that the last four should be digits for ex:
AP1234 something like this it and it shldnt have 0000 at the last ...
float put;
put = 6/120;
cout << put;
This outputs 0. Why is it so and how can I make it output 6/120 in a more precise way?

Your table must display 6 numbers per row and use a spacing of 10 for each number. Don’t forget to include the header file “iomanip” at the top and use “setw()”. You will need to turn in an algorithm, source code and output.

We were asked to make a program which displays the prime numbers within the range you inputted... like for example i entered 20 as the upper limit and 1 as the lower, then the program must display all prime numbers within 20 and 1..
and so my problem is, i get to display the prime numbers, but 2, 3, 5, and 7 can't because it think it's with the if statement i made within the loop? (Code below)
#include<iostream.h>
#include<conio.h>

This code is suppose to display arithmetic sequence after it has to add all the numbers together without a formula.
for example: the starting number is 5, common difference is 3, the term is 9
the sequence would display as: 5, 8, 11, 14, 17, 20, 23, 26, 29
the sum is: 153
with my code I've managed to get 8,11
To get the sum, I am restricted to using a "for" loop. For sequence, I am using a while. I am trouble developing the while loop to display the sequence and getting the sum for the for loop.

I have everything down except for the highest # and lowest number being displayed.
The arrays are 23, 4, 76, 89, 12, 43, 37, 67, 21, 14.
I have the average which is 38.6 but i stuck getting highest number and lowest.
What shall I learn in order to send values from 0.00 to 5.00? I'm working with they Hitachi 16x2 LCD display.I've been sending/displaying literal values on it all day.
Code:
SendCharater(unsigned char val)
where the variable val corresponds to the LCD character table.I can also send Hello World to the display, like so:
Code:
void putsXLCD(unsigned char *buffer){
while(*buffer) // Write data to LCD up to null
{
while( BusyXLCD() ); // Wait while LCD is busy
SendCharacter(*buffer); // Write character to LCD
buffer++; // Increment buffer
}
return;
}
I could type in putsXLCD("5.00") in order to display it on the LCD, but how do I implement this automatically for values, e.g. 0.00 to 5.00?It appears I can only pass literal values through the function SendCharacter, meaning that in order to display "0" I have to pass the value 0x30 (the hex value of "0" on the LCD Table).
My current thought process:Much like passing "Hello World" in the function putsXLCD(), I need to assign a pointer that points at each value in the "array" that I need to send. E.g., I need to send 3.24, so I need to point to "3", fetch the corresponding hex value in the LCD table, in this case 0x34, and the pass this 0x34 into the SendCharacter function, and so on. So, if this is the case, how can I fetch the corresponding hex value?
