C Program to Display Prime Numbers Between Two Intervals

C Program to Display Prime Numbers Between Two Intervals


Input & Output:

Enter the interval:
2
15

Prime numbers between interval 2 and 15 are:
3               5           7            11            13

Implementation:

#include<stdio.h> #include<conio.h> int main() { int min,max,i,j,flag; printf("Enter the interval:"); scanf("%d%d",&min,&max); printf("Prime numbers between interval %d and %d are:\n",min,max); for(i=min+1;i<max;i++) { flag=0; for(j=2;j<=i/2;j++) { if(i%j==0) { flag=1; break; } } if(flag==0) printf("%d\t",i); } return 0; }
