C Practical and Assignment Programs-Prime Factorization

C Practical and Assignment Programs-Prime Factorization
It is the most common question asked in aptitude and interview.
In this video we are going to write a program to find the prime factors of given number. This program will print all the prime factors of the give number. But in this video we will also see how to organize code for better readability and re usability. Now this program is written in C programming language but will work in C++.Fell free to provide you suggestion.

can i put the prime factorization function inside the main function so that I dont have to put FindPrimeFactorization(n)

[isaacblue]

any way of doing this without having to put the primefactorization in the int main () function?

How to print the factors in descending order?
I tried this:
i=num;
and in the while loop, decremented the counter value i. Example: for 60, results are 30 2

[vijayboda]

why we should do { n=n/i } after printf.

[andytheodorko]

Why don't you use the for loop?
//My version
for (ull i=2; i<=number and i*i<=number; ++i)
{

// integer division
while (number%i == 0)
{

cout<<i<<" ";

number /= i; // number = 28/2 = 14; n = number * 2**1
}

}

if (number != 1) // n=6, i=3, number = 3
{

cout<<number;
}

Bro, can you tell us the code for SUM OF UNIQUE NUMBERS IN AN ARRAY
Ex:11, 12, 13, 12, 11, 11, 12
Sum:13
Thanks in advance

this is wrong, i tried to input 720, and there is 4 on the result, 4 is not prime factor

[mehedirafi]

Bro, how can I print like this:
1  2   3   4
5           8
9 10 11 12

will be grateful....

write a program to display first x prime numbers in reverse order displaying 10 numbers in row.Only the alternate prime number should be displayed and considered.I want this answer, this type of questions asked in interview as a system test
how to do it easily!

I don't see why your inner while loop is necessary... Here is my solution:
int N = 66;
int D = 2;
while(N!=1)
if(N%D)
D++;
else {
printf("%i ", D);
N = N/D;
}

would u print 
2
3       5
7       11      13
17      19      23      29
31      37      41      43      47

using for loops with a video explanation maybe.
