int i=2; // using 2 because every no is divisible by 1
boolean prime=false;
loop : while(i<n){
if(n%i==0){
prime = true;
break loop;
}
i++;
}
System.out.println(prime); // prints true if no is prime, false if it's not

∙ 8y agoA single input (the number) would look something like...
public static void main(String args) {
try {
// Get an integer
int num = Integer.parseInt(args)
// Must divide by something... start at two
int denom = 2;
// Keep dividing by larger numbers until there's no remainder
// or there's nothing left to try.
// Could probably stop even sooner, but just a sample answer
while(num % denom != 0 && denom < num){
denom++;
}
// If the while loop finished early, it's Optimus!
if(denom < num) {
System.out.println("We have a prime!");
} else {
System.out.println("Not prime... must be Megatron");
}
} catch (ParseException pe) {
System.out.println("Not prime; only integers can be prime. Input an integer number.");
}
}

How can you Write a suitable pseudo code to check whether a number is prime or not?
Begin Read num for(i=2; i<num; i++) if(num%2==0) then print "the number is not a prime no."; else if print "the number is prime"; end if Stop
Write a c program to check whether a no is prime or not?
#include<stdio.h> #include<conio.h> int i=1, count=0,n; clrscr(); printf("Enter Any Number"); scanf("%d", &n); while(i<n) if(n%i==0) { count++; i++; } if(count==2) printf("Given Number is Prime"); else printf("Given Number is not Prime"); getch(); }
Write a c program to find out the prime numbers between 1 to 500?
Here is a simple program to generate prime numbers upto a given specific number /*Prime No. from 1 to 50*/ /*By-Himanshu Rathee*/ #include<stdio.h> #include<conio.h> void main() { int i,j,n; clrscr(); printf(" Enter the number upto which we have to find the prime number: "); scanf("%d",&n); printf("\n"); for(i=2;i<=n;i++) { for(j=2;j<=i-1;j++) if(i%j==0) break; /*Number is divisble by some other number. So break out*/ if(i==j) printf("\t%d",i); /*Number was divisible by itself (that is, i was same as j)*/ } /*Continue loop upto nth number*/ getch(); }
Prime number program in C using recursion?
//Program to check number is prime or not using recursive function #include<stdio.h> #include<stdlib.h> void prime(int num,int count) { if(count<num) { if(num%count==0) { printf("%d is not Prime Number\n",num); goto exit; } count += 1; if(count<num) { prime(num,count); } } if(num==count) { printf("%d is a Prime Number\n",num); } exit: return 0; } int main() { system("cls"); int gvar; printf("Enter the number = "); scanf("%d",&gvar); prime(gvar,2); printf("\nashokakhil@gmail.com\n"); system("PAUSE"); return 0; } I think this can be another solution #include<stdio.h> #include<conio.h> int prime(int); main() { int i=1,r; clrscr(); r=prime(i); if(r==1) printf("\n\n\tNo is prime "); getch(); } int prime(int i) { int n=1,ans,flag=1; i++; ans=n%i; if(ans==0) { printf("\t\t\n\nNo is not prime"); flag=0; return flag; } if((i!=n-1)&&(n!=1)) flag=prime(i); return flag; }
Shell program for finding prime number?
#!/bin/sh i=2 rem=1 echo -e "Enter a number: \c" read num if [ $num -lt 2 ]; then echo -e "$num is not prime\n" exit 0 fi while [ $i -le `expr $num / 2` -a $rem -ne 0 ]; do rem=`expr $num % $i` i=`expr $i + 1` done if [ $rem -ne 0 ]; then echo -e "$num is prime\n" else echo -e "$num is not prime\n" fi

A program to find that the input number is prime or not?
Use Wolfram|Alpha... go to the related link below, Wolfram|Alpha, and type in (is __ (number) prime) and then the program will compute that and tell you if it is prime or composite.
Program for print prime all number from 1 to 100 in foxpro?
Prime numbers are numbers that are only divisible by themselves and the number 1. You can write a program to print all prime numbers from 1 to 100 in FoxPro.
What is the largest prime no that is stored in 8 bit pattern?
Write your own prime number program and find out.
What is the code of a c program that will read in a positive integer value and determine If the integer is a prime number and If the integer is a Fibonacci number?

Prime numbers between 1 to 10 in microprocessor 8085?

Write a java program to display the number is prime or not?
Simply use a for loop (i) that runs from 2 to N-1. Checking if N % i 0 then its a prime number.
With a given big integer number which is the product of two prime numbers how do you find them?
First write a program to generate the prime number. After one prime number was generated, divide the big int number by the prime number. If the remainder is zero then quotient is the second prime number ( also it is important to check whether the quotient is prime number or not because sometimes you will get wrong answer). Repeat the process until you get the result.
What is the Program for composite and prime numbers in c?
#include<iostream.h> #include<conio.h> int main() { int i,n; clrscr(); cout<<"PROGRAM TO CHECK IF THE NUMBER IS PRIME OR NOT:"<<endl; cout<<"Enter a number:"; cin>>n; for(int i=2;i<n;i++) { if(n%i==0) cout<<"\nTHE NUMBER IS COMPOSITE"<<endl; else cout<<"\nTHE NUMBER IS PRIME"<<endl; } return 0; }
Shell program to generate prime number between 1 and 50?
There are several shell programs available for download on the Internet that will generate prime numbers. The best way to find a prime number is through calculation, however.
How do you program if it is a prime or composite?
The easiest, but not the most efficient way, to program this is to take your number "n" and test all the numbers from 2 to n-1 to see if they divide n, if none of them do, then n is prime.
How can I write a program to display prime numbers from 1 to 100?
Write a function that implements an algorithm that checks to see if a particular integer is prime (returning a boolean). Write a program that uses that function on each number from 1 to 100, and if true, displays that number.
