Answer:Following is the c+ + code for the problem:

#include

using namespace std;

int main () {

int number;

cout<<"Enter the number"<
cin>>number;

int i=0, c=0, odd[500];

while (i<=number) / /loop for printing the numbers form 0 to number.

{

cout<
if (i%2!=0) / / storing in the odd array if the number is odd.

{

odd[c++]=i; //storing odd numbers ...

}

i++;

}

cout<
i=0;

cout<<"The odd numbers are "<
while (i
{

cout<
i++;

}

cout<
i=0;

int sum=0;

while (i
{

int div=2;

while (div
{

if (odd[i]%div==0)

break;

div++;

}

if (div==odd[i])

{

cout<
sum+=odd[i]; //updating the sum ...

}

i++;

}

cout<
return 0;

}

Output:

Enter the number

49

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

The odd numbers are

1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49

The prime numbers are

3 5 7 11 13 17 19 23 29 31 37 41 43 47

The sum of odd prime numbers is 326.

Explanation:

First I have printed the values from 0 to n and i have taken an array to store odd numbers. After that i have printed the odd values. And after that i have printed prime numbers among the odd numbers and their sum. These all operations are done using while loop.
