Multiple messages
This program works okay except it prints the same messages more than once for unmatched letter. Can anyone give a solution to this?The programs very easy....
Code:#include<stdio.h> int main(void) { int tries = 0; char pass; for(tries = 0;tries<=5;tries++) { printf("Enter a letter to pass"); pass = getchar(); if(pass == 'b') {printf("welcome aboard"); break;} else {printf("try again \n");} } return 0; }
Perhaps add
Code:else if ( pass == '\n' ) { // ignore newlines }
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
I would change the getchar() line to
scanf(" %c",&pass);
Note the space before the %c - that will eliminate your troublesome newline, each time.
Well it removed one of the messages...but the first message "Enter a letter to pass" pops up twice as before...
I used scanf but the program stops by giving the message "This program has stopped working" message...
