Display Prime Numbers Between two Intervals
#include <stdio.h> int main() { int low, high, i, flag; printf("Enter two numbers(intervals): "); scanf("%d %d", &low, &high); printf("Prime numbers between %d and %d are: ", low, high); while (low < high) { flag = 0; for(i = 2; i <= low/2; ++i) { if(low % i == 0) { flag = 1; break; } } if (flag == 0) printf("%d ", low); ++low; } return 0; }
