# C Program to Display Prime Numbers Between Two numbers

C programming is a preferred cause extensively used excessive stage programming language. Nearly all kinds of pc packages are written in this language. It’s far the simple programming language. Write a c program to find prime number among two numbers inputted by using person. We can additionally learn how to display prime quantity between 1 to n numbers. Now first we find out about prime numbers. Top no among no
write a c application to print all high numbers between 1 to n the usage of for loop. Write in c to print prime numbers among 1 and 100. Required knowledge

## c print f and scan-f capabilities

for loop in c
define top range in C Program
a prime number is a natural wide variety greater than 1 this is most effective divisible through both 1 or itself. All numbers aside from prime numbers are known as composite numbers. There are infinitely many top numbers, here is the list of first few top numbers
2 three five 7 11 thirteen 17 19 23 29 31 37…. Step 1. In step 1 processors are given to consist of header report for top numbers
step 2. We used essential characteristic

### step 3. We’ve declared variables

step four. Two numbers are inputted with the assist of print f and experiment f fiction. Step 5. In this step external loop is given here we for loop which increase their fee from 1 to subsequent and so on

### algorithm for prime no

we just write algorithm for 1 to n number you can exchange it in keeping with your want and requirements
algorithm. Algorithm to check whether or not quite a number is high or not
permit, n be a high-quality wide variety. For every number i, among 2 to n/2(2<= i <= n/2) check whether or not i divide n absolutely(take a look at if i is a issue of n). If (n % i == zero), then n cannot be a high wide variety. If none of the wide variety among 2 to n/2 divides n completely then n is a top quantity.

### Instance of software

#consist of<stdio. H>
#include<conio. H>
void fundamental()

clrscr();
long i,prime,j,n1,n2;
printf(“input start and cease numbers for high”);
scanf(“%ld %ld”,&n1,&n2);
for(i=n1;i<=n2;i++)

prime=1;
for(j=2;j<i;j++)

if(ip. Cj==0)

high=0;
ruin;

if(top==1)
printf(“%ldt”,i);

getch();

output

input numbers(intervals): 20
50
top numbers between 20 and 50 are: 23 29 31 37 41 43 47
