# Prime Show

Best Prime Example Is Availble in my another post. Kindly check.

problem:
Write a program to show prime from 0 to N  where N will be taken from user.
code:

```#include<stdio.h>
int main()
{
int i,j,count=0,N;
printf("Enter N:");
scanf("%d",&N);
printf("prime = ");
for(i=1; i<=N; i++)
{
for(j=1; j<=i; j++)
{
if(i%j==0)
count++;
}
if(count==2)
printf("%d\t",i);
count=0;
}
return 0;
}```

Another Logic:

```#include<stdio.h>
int main()
{
int i,j,N,isPrime;
while(1){
printf("enter value:\n");
scanf("%d",&N);
for(i=2; i<=N; i++)
{
isPrime=0;
for(j=2; j<=i/2; j++)
{
if(i%j==0){
isPrime=1;
}
}
if(isPrime==0 && N!=1)
{
printf("%d\t",i);
}
}
printf("\n");
}
return 0;
}```

Another Logic collected from this link:

Understood the implementation of the code.

It would be a great help, if you support by sharing :)
