AIM: Write a program to covert C to C++ for Prime Number.
SOURCE CODE:
IN C:
#include<stdio.h>
main()
{
int i,n,f_count;
printf(“Enter the value of n:”);
scanf(“%d”,n);
for(i=1;i<n;i++)
{
if(n%i==0)
f_count++;
}
if(f_count==2)
printf(“it is a prime number”);
else
printf(“it is not a prime number”);
}
In C++
#include<iostream>
using namespace std;
int main()
{
int i,n,f_count=1;
cout<<“\n enter a number:”;
cin>>n;
for(i=1;i<n;i++)
{
if(n%i==0)
f_count++;
}
if(f_count==2)
{
cout<<“\n it is a prime number”;
}
else
{
cout<<“\n it is not a prime number”;
}
}
OUTPUT:
Enter a number: 97
it is a prime number
Enter a number: 972
it is not a prime number
AIM: Write a program to convert C to C++ for Even or odd.
SOURCE CODE:
In C:
#include<stdio.h>
void main()
{
int n;
printf(“Enter a number: ”);
scanf(“%d”,&n);
if(n%2==1)
printf(“Given number is ODD\n”);
else
printf(“Given number is EVEN\n”);
}
In C++:
#include<iostream>
using namespace std;
int main()
{
int n;
cout<<“\n Enter a number: “;
cin>>n;
if(n%2==1)
cout<<“Given number is ODD\n”;
else
cout<<“Given number is EVEN\n”;
return 0;
}
OUTPUT:
Enter a number: 96
Given number is EVEN
Enter a number: 87
Given number is ODD
