6. Write a function to find whether a given no. is prime or not. Use the same to generate the prime numbers less than 100.

 #include <stdio.h> 

int checkPrime(int N) 

{ 

int flag = 1; 

for (int i = 2; i <= N / 2; i++) { 

if (N % i == 0) { 

flag = 0; 

break; 

} 

} 

return flag ; 

} 

int main() 

{ 

for(int i=1;i<=100;i++)

if(checkPrime(i)&&i!=1)

    printf("%d ",i);

return 0;

}
