Operator C Tutorial

You can combine multiple relations or logical operations by logical operation.
The logical operators are negation (!), logical AND (&&), and logical OR (||),

#include
main(){
  int c1 = 1,c2 = 2,c3 = 3;
  if((c1 < c2) && (c1     printf("\n c1 is less than c2 and c3");
  }
  if (!(c1< c2)){
     printf("\n c1 is greater than c2");
  }
  if ((c1 < c2)||(c1 < c3)){
     printf("\n c1 is less than c2 or c3 or both");
  }
}
c1 is less than c2 and c3
c1 is less than c2 or c3 or both
