Program to print Prime Numbers in a Range in C
If Prime Numbers should be printed between range then while loop must be iterated range-1 times. For this we have to declare low range and high range. Here is the example of Program to print Prime Numbers in a Range.
#include <stdio.h>
int main()
{
int l,h,i,j,set;
printf("Enter two numbers(intervals): ");
scanf("%d %d", &l, &h);
printf("Prime numbers between %d and %d are: ", l,h);
while(l<h)
{
if(l==1)//ignoring if first element is 1
{
l++;
continue;
}
set=0;
for (i = 2; i <= l / 2; ++i)
{
if (l%i==0)
{
set=1;
break;
}
}
if (set==0)
printf("%d ",l);
l++;
}
return 0;
}Enter two numbers(intervals): 10
30
Prime numbers between 10 and 30 are: 11 13 17 19 23 29
