C++ :: Program To Find Smallest Real Factor Of A Number

Oct 10, 2013

I need codes for a program in C or C++ that will show the real factor (the smallest one, without the number 1) when an integer is given as input.

When the program is started, it will ask to enter a number and press enter. After entering a number, it will first check if it is a prime number or not. If prime, it will notice that it is a prime number, otherwise, it will print the smallest real factor of the given integer.

For example, if 12 is entered, it will print, the smallest real factor for this number is: 2

If 27 is entered, it will print, the smallest real factor for this number is: 3

...and so on

Mar 6, 2015

How to find the largest and smallest number entered by a user. So far I'm able to add, find the average and count how many numbers are entered.

I'm just having trouble with find the max and min. I tried if statements and it breaks the program will it wont let me exit the while loop or the program will do a force close after entering a value.

Code:

#include <stdio.h>
#include <stdlib.h>
int main(){

int maxNum=0, minNum=0, value, count=0, sum=0;

C :: Function To Round A Number To Give Integer Number That Is Closer To Real Value

Oct 9, 2013

I was told to use a round function to round a number to give an integer number that is closer to the real value. (for example if the number is 114.67 I need to print an int value of 115 instead of 114)

I am not exactly sure how a round function works, but I am told to include math.h library. What I try doesn't seem to work.

C :: Efficiently Multiplies A Number By A Factor 2

May 1, 2013

Write a C-program that efficiently multiplies a number by a factor 2 to the power n. The number to multiply and n are variables, which get a value at the start of the program.

Clue: 1 shift to the left is the same as multiplying by 2. 2 shifts to the left are the same as multiplying by 4. 3 shifts to the left are the same as multiplying by 8

C++ :: Finding Largest Prime Factor Of A Number?

Mar 10, 2013

I am trying to find the largest prime factor of a number. But when I am trying to determine if a number is a prime number in the function:

int is_prime(int number), I am unable to exit the loop.

Here is the code:

#include<iostream>
using namespace std;
int is_prime(int number) //the problem is in this function {
int num = number;
int factor=0;
do{
num++;
for(int i=1;i<(num+1);i++){

[code].....

So when the program runs, it first divides 20 by 2, to get 10, then divides 10 by 2 to get 5. Since, // condition 1 is not met, it passes 2 to the function int is_prime(int number). The function is able to return 3, but cannot exit the loop when num is 4.

I think the problem lies in the function: int is_prime(int number).

C :: How To Generate Real Number Between 0 And 1

Mar 1, 2015

I am a very very beginner at programming with C. Well, basically i have to generate a real number between 0 and 1 (which as the same as from 0 to 100 k and than dividing everything with 100 k).

Why I am constantly talking about 100 k? Because I would need approx 50 000 random numbers between 0 and 1. My code currently looks something like this:

Code:

int main(int argc, char** argv) { int min,max;
double number;
srand((unsigned)time(NULL));
number = 1 + rand()%100;
printf("The number is: %lf",number);
sleep(2);
return (EXIT_SUCCESS);
}

And If I am not mistaken, should generate numbers between 0 and 100. But I can't figure it out how to change to code in order to get enough numbers.

C :: Generate Pseudo Random Real Number From Interval (0,1)

Feb 6, 2013

How can I generate a pseudo-random real number from interval [0,1] ?

Can it be generalized to any interval? Like [0,a], where 'a' is a parameter?

I tried searching for it, I only found rand(), srand(), random(1), and randomize. None of it actually seems to work for me..

Later I actually succeeded with something like

srand( (unsigned)time( NULL ) );
printf( " %6d
", rand() );

but it only produces up to five digits integers and I cannot divide by 99999 to get it into [0,1].

C++ :: How To Generate Real Random Number From Normal Distribution

Jun 26, 2013

I want to generate random numbers of normal distribution and use scentence like

std::default_random_engine generator;
std::normal_distribution<double> distribution(0,1);
arrayX[i][j]=distribution(generator);

But I find that each time the array I got are the same. So how should I generate random numbers with different seedings with normal distribution?

C :: Find Smallest / Largest And Average Values In A Collection Of N Numbers

May 30, 2014

I seem to have reached a dead end in a program I am attempting to write.The purpose of the program is find the smallest, largest, and average values in a collection of N numbers. It needs to get the value of N before scanning each value in the collection of N numbers.I'm having trouble creating comparisons for each set. I have a feeling because of the way I structured my program, I'm unable to make a proper comparison. Maybe my approach was wrong as soon as I got to the for statement to loop N sets and N numbers.Here is my code so far:

Code:

#include <stdio.h>
int main (void)
{
int num_sets, num_of_integers;
int count, count2, set, sum = 0;
int num, avg;
}

[code]....

/* Here is where I would continue to attempt to make a comparison between sets to determine smallest to largest */

return 0;

C/C++ :: Determine Smallest Number Xmin

Jan 21, 2014

In a fashion similar to that in Fig. 3.11(shown below), write a short program to determine the smallest number, xmin, used on the computer you will be employing along with this book. Note that your computer will be unable to reliably distinguish between zero and a quantity that is smaller than this number.

C :: Function Call To Print Smallest Number?

Mar 15, 2013

C programming, make it use a function call to print the smallest number? this is a program which prints out the smallest of three numbers within the main function that I was asked to write.Now the other question i am asked,5. Re-write the program, uses a function call to print the smallest number?

Code:

# include <stdio.h>

main()
{
int a,b,c;
int temp, min;
a = 100;
b = 23;
c = 5;

C :: Program To Find The Square Root Of A Number

Dec 5, 2013

I am writing a program to find the square root of a number. I am using the Newton-Raphson method..Just to clarify a bit of the code.. fabs(1/(x+1)) < 0.001 is to check for relative error..

EXAMPLE: for user entry of 100 if the iteration process ends in 10.055 the answer will return as 10 which is correct. But it isn't doing that.

It compiles I then proceed to run it..prompts me "Enter a number to find the square root of: I type 100 then hit enter...

"The square root of 100 is -1077834936"

My first time writing a program from complete scratch.

And I know there is a sqrt() function...just wanted to write my own.

Code:

#include <stdio.h>
#include <math.h>
double mysqrt(double a);
int main()
{
double a, result;
printf("Enter a number to find the square root of: ");

[Code]...
