char - Switch Statement Not Executing Cases (c) -


i made switch statement, however, works constants set. if try use user input, 1 of cases work, every other 1 doesn't. no matter enter, uses default case. tried adding getchar() clear \n character buffer isn't making difference. ill post entire switch statement here :

      char option=' ';       option=getchar();       switch(option){          //parallel resistance calculations         case 'p':             clear             //presistance();             printf("resistance");             getchar();             break;          //ohm's law calculations         case 'o':             clear             printf("ohm");             //ohm();             break;          //exits program         case 'q':             printf("good bye! stay safe in laboratory! :)\npress key exit");             getchar();             exit(0);             break;          //error checking         default :             printf("invalid input, try again");              break;      }   } while (option!='q');

i commented out functions use print statements test if working.

whenever input character or string stdin in c, make sure there no \n in input buffer. this, getchar() after taking integer or float inputs.

in case, maybe you've inputted integer before inputting character. try write getchar() before taking character input.
