What input you will give to write a basic program to find prime numbers between 1 to 100 using if and else?

Answer 1

#include <iostream> void main() { using namespace std; int num, rem, sum=0; //Declaring variables cout<<"Enter a number :"<<endl; cin>>num; //Loop to calculate the sum of the digits of the given number. while(num!=0) { rem=num%10; num=num/10; sum=sum+rem; } cout<<"Sum of the digits is "<<sum<<endl; cin.get(); }

Answer 2

class prime

{

public static void main(String p[])

{

int i,j,s=0,d=0;

for(i=1;i<100;i++)

{

s=0;

for(j=1;j<=i;j++)

{

if(i%j==0)

s=s+1;

}

if(s==2)

{

System.out.println(i);

d=d+1;

}

}

System.out.println("the no. of prime no. are = "+d);

}

}

Answer 4

There is nothing needed as input.

But if "input" as the argument passing to a routine, it depends on the routine.

It can be a function to determine any given integer (here's the input) is a prime or not, or it can be a function to return all the prime numbers within a range (1 to 100 in this case).

• the smallest Prime = 2, the only even number as a Prime number!
• any other prime number other than 2 is a POSITIVE ODD INTEGER
