    void main(void){
        int no;
        int ir, hr;


        no = -1;

        if (no > 0);       /*  ; here means end of statement so the printf immediately below is not part of the if */
            printf("positive!\n");


        no = 0;

        if ( no  = 1)       /* == means test for equality = means assign. If no is assigned 1 that means true in C.   */
             printf(" equal!\n");
        else
             printf("not equal!\n");
  

         no = 2;



         switch(no){
             case 1:  printf("one ");
