Write a c program to find out the prime numbers between 1 to 500?

Answer 1

To write a C program to find prime numbers between 1 to 500, you can use a nested loop structure. In the outer loop, iterate from 2 to 500, and in the inner loop, check if the number is divisible by any number from 2 to the square root of the number. If it is not divisible by any number other than 1 and itself, then it is a Prime number. Print out all prime numbers found within the specified range. Remember to include necessary header files, such as <stdio.h>, and use appropriate logic to implement the program efficiently.

Answer 2

Oh, dude, you wanna find prime numbers? Alright, here's a simple C program for ya: You loop through numbers from 1 to 500, check if each number is prime by dividing it only by numbers up to its square root (efficient, right?), and if it's only divisible by 1 and itself, boom, you got a prime number. Print those bad boys out and voilà, you're done. Like, easy peasy, lemon squeezy!

Answer 3

Oh, what a lovely request! To find prime numbers between 1 to 500 in a C program, you can use a nested loop. Start by checking each number from 1 to 500 if it's prime by dividing it only by numbers up to its square root. If a number is only divisible by 1 and itself, then it's a prime number. Happy coding and enjoy the process of discovering these special numbers!

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();

}

Answer 5

#include <iostream>

#include <math.h>

using namespace std;

int knum;

int i = 1;

int pt = 0;

bool is_prime;

int main()

{

cout << endl << endl;

cout << "This Program calulates the prime numbers between" << endl;

cout << "a given start and end number.";

start: cout << endl << endl << "Please enter a starting number (enter 0 to exit): ";

cin >> i;

if (i 0)

is_prime = false;

}// only when the "for" cycle is done we know for sure if "i" is prime

if (is_prime)

cout << i << ", ";

i++;

}

goto start;

close: cin.get();

return 0;

system("pause");

}
