have this program .. i tried to make it work to give me this result output:
Code:
input array {1,3,5,1,1,8,6,6,1,3,2,1,6,8,8}
[0]
[1] *****
[2]*

instead i'm having asterisks at the end of the output
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):********************************************

I am having problems doing the fourier transform:
[URL] .....
My code is:
esc = 2;
maxi = 0;
fu = 500;
fo = 3000;
for (f=fu;f<=fo;f + esc) {
[Code] ....
Don't worry about the exp and complex numbers because they work correctly. N is the number of samples of the input (2500). Esc is the difference between different frequences. So the samples of the output are (1250).
I'm taking a C++ computer science course right now, and one of the questions on my latest assignment is this:
"A partition of an integer n is a way of writing n as a sum of positive integers. For example, for n=7, a partition is 1+1+5. Write a program that finds all the partitions of an integer n using r integers. For example, all the partitions of n=7 using r=3 integers are 1+1+5, 1+2+4, 1+3+3, 2+2+3."
I've been struggling with this problem for a couple days now, and how to do it. I understand I need a recursive function to grab variables, and probably an array or vector to store them, but where to begin.
I've been reading documents on partition generating and the concept still eludes me, and any other questions on here or other programming sites using partitions don't seem to have a constraint on them.
I'm trying to create a program that will play scales at certain frequencies, but my arrays are not initializing correctly. I've read up to double check what i'm doing but it doesn't seem to be working. My only guess is my use of a global variable.
const int NotesInScale = 8;
class Scales {
private:
//all Major Scales
int CMajor[NotesInScale];
int GMajor[NotesInScale];
[Code] ....
i'm simply trying to put the frequencies in the scales (the numbers in the array) but I keep getting an error. I feel its a simple fix but i'm not seeing it.
I've got this assignment where I have to print every other number from 1 to 10.
so far I've got this.
#include <iostream>
using namespace std;
int main() {

wondering if its really counting from 1 to 10 and only printing every other number.
The program requires the user to enter 10 integers then print the total no. of even integer,highest even integer, lowest even integer then total no. of odd integer,highest odd integer, lowest odd integer
I already got the total no. of even integer and total no. of odd integer. But I don't know how will i get the highest even integer, lowest even integer and highest odd integer, lowest odd integer.
I have been trying to write a recursive function to print the permutations of a n-digit number. This is the logic that i am trying to use.
1.call the permutation function,
2.keep the first digit in the first place and send the remaining 2 digits back to the permutation function recursively.
3.keep one of the two digits received and send the remaining digit to the permute function.
4. keep doing this till only one digit remains. this is the smallest solution so return it.
how to make a program in which a user is prompted to input four numbers like 1234 and then print those four numbers one by one on screen using only one variable..??
For example:
1
2
3
4
in ascending order...
I've done that with two methods but i am not sure whether the methods were correct..
I write this program to print the number of days for the month when the year and the month enters. This is not giving any result and i think that problem is with calling functions.

int leap_year(int year);
string days(string mounth);
string feb(string fab1);
void main(){

Program that has the user enter 5 digits then asks the user what they want to know about the 5 digits. My issue is when the program goes to print the value, its a totally ill related number
10 34 8 17 50
program prints out:
2 for smallest
79 for largest
119 for sum
23.80 for average
Code:
#include <stdio.h>#include <stdlib.h>
int main(void)
{
int smallNum, largNum, count=0, sum=0, value, choice;
double avgNum;
printf("Enter 5 integers
");
printf("

Why my program doesn't work? Print number of vowels case-insensitively. For instance in the expression “come here”, there are 4 vowels.
#include <stdio.h>
#include <stdlib.h>
int vowels(char sentence[], char vowelletters[], int max) {
int vowelcounter=0;
int i,j=0;
[Code] ....
it just count one vowels not more.
I want to have one case of my switch statement to print out how many times the user has chosen other cases in the switch statement. Such as "You have pressed 2 6 times and 4 3 times."

I have following code to create histogram, but it gave wrong output. In the program input_vector read 100 double numbers. I want to create a histogram with bin size=5. Output is [0;0;0;0;0].

I'm trying to code one of the problems but it really is hard to catch errors for a novice like me at first.
I have to Write a single C function for computing the histogram of a list of nonnegative integers into 4 bins.
The main() function first initializes a positive integer array called List of size N, takes 3 inputs from the user A, B, C (assume 0 < A < B < C), and declares a second integer array Bin[4].
The doBinning function should count the number of elements of List in the interval [0, A) and store it in Bin[0], count of [A, B) in Bin[1], count of elements in [B,C) in Bin[2], and the number of elements >= C in Bin[3]
Code:
#include <stdio.h>
#define N 10
#define M 4
int *doBinning (int source[], int dest[], int a, int b, int c);
int main (){
[Code] ....
Somehow I keep getting error from ptr = doBinning(List[], Bins[]. What am I doing wrong? Code might contain some errors.
I need a C code for generating a Histogram with intensities at X-axis and number of pixels at Y-axis from a PGM format image.
View 5 Replies View RelatedScaling the yaxis on my histogram for one of my class projects. I've gotten mostly everything but stuck on scaling. I'm pretty sure it's something simple to do, but I'm having trouble, and I've tried everything to my knowledge to get it scaled from 0.1 - 1, like this:
Here is my code:
#include<stdio.h> //include all preprocessor directives
#include<Windows.h>
int main(void) {
int MAX = 0; //initialize and declare variables
int allcounts [10] = {0}; //store an array of integers for

I'm close, but every time I try and change my y axis in the for loop from 1 going down to 0.1, it doesn't give me a right output.
I have a text file which consist of several values. These values represent distance from origin to any point in the triangle. How can I create histogram from these values? Is there any functions in OpenCV which can create histogram from these values?
Below my sample values are given:

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 have an assignment on image processing and amongst other question one of them specifies:calculate the equalized histogram of a grayscale image and show statistical data of your choice between the input and output images.
I am having trouble equalizing the histogram. Either I am missing the whole picture or minor details that cause problems.
Code:
// original histogram
for (i=0; i<lines; i++)
for (j=0; j<columns; j++)
hist[image_in[i][j]]++;
//histogram max and min
int hmax=-1,hmin=257;
for(int i=0;i<256;i++) {

I am thinking that my equalization formula is wrong, i might have incorrectly translated the mathematical formula from wikipedia to C code but i cant figure out why.

I am doing Histogram using pthreads and after long struggle on it.. finally it says 'Segmentation Fault (Core Dumped)'. I knew that error means something somewhere I am accessing to a wrong memory location.

#include <pthread.h>
void Usage(char prog_name[]);
void Gen_data(void *p);

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.
I want to create a vertical histogram in my code. I already made it go vertical but not the way I want it.
Example:
I want it like this:
Range1 Range2 Range3 Range4
And asterisks under each one, depending on the user input. (My code is below and doing it on here doesn't make it come out correctly)
But what I've managed to do is this:
Range1
*
*
*
Range2
*
*
Range3
*
*
*
*
Range4
*
*
Which I don't want. I want everything else to stay pretty much the same since I can only use some features such as Arrays and really basic functions.
Here is my code: (Worked fine last time I used it and I am doing it on Visual Studio 2010 (at uni) and 2013 (on my laptop)).

//Counter variables for ranges in While Loop
int counterlow; //Counter for low range
int countermidlow; //Counter for mid-low range
int countermidhigh; //Counter for mid-high range
int counterhigh; //Counter for high range

Write a program to print a histogram of the lengths of words in its input. It is easy to draw the histogram with the bars horizontal; a vertical orientation is more challenging.
See [URL] ....
I'm trying to do this exercise from K&R on my own (with my own code), but I'm receiving a signal (Illegal instruction (Core dumped)) when the input is too large.
#include <stdio.h>
#define MAXWORDLENGTH 10
int main(void) {
int c; /* Character read */
long length[MAXWORDLENGTH + 1];
int reading_word = 0;
int word_size = 0;
