Small looping problem

Sorry if you have seen this code already, but I have fixed it to almost work perfectly. My issue this time, is that, when A character is entered exceeding 9 characters, my program does not proceed to the appropreate loop.

Example of error:

Code:

Enter words no longer than 9 characters Enter your 1st word :Bill Enter your 2nd word :thiswillbemorethannine Enter your 3rd word :Enter your 4th word :

The character checking loop is as follows;

Code:

for (b=0; b<10; b++) { buff[a][b]=fgetc(stdin); if (buff[a][b]=='\n') { buff[a][b]='\0'; break; } if (b>=10) { printf("You have entered a word more than 9 characters\n"); while((buff[a][b] = fgetc(stdin))!='\n') { a=-1; goto A; } } }

Maybe I miss understand how loops work, but when 'b' gets increased to 9, the loop runs, then does it get increased to 10, and not follow through with the loop because b<10 is FALSE? Thats my logic of it, so since b = 10 now, it should do my ERROR loop.

I know for a fact the loop above doesn't remove all the information in the buffer, so I don't exactly know how to do that either. (I can't use fflush)

Here is my program;

Code:

#include <stdio.h> #include <string.h> char word[10][19]; char buff[10][19]; int a,b,c,d,e; int main () { printf("Enter words no longer than 9 characters\n"); A:for (a=0; a<10; a++) { if (a==0) printf("Enter your 1st word:"); else if (a==1) printf("Enter your 2nd word:"); else if (a==2) printf("Enter your 3rd word:"); else printf("Enter your %dth word:", a+1); for (b=0; b<10; b++) { buff[a][b]=fgetc(stdin); if (buff[a][b]=='\n') { buff[a][b]='\0'; break; } if (b>=10) { printf("You have entered a word more than 9 characters\n"); while((buff[a][b] = fgetc(stdin))!='\n') { a=-1; goto A; } } } for (b=0; buff[a][b]!='\0'; b++) if (buff[a][b] >='a' && buff[a][b]<='z') buff[a][b]=buff[a][b] - 'a' + 'A'; else if (buff[a][b] >='A' && buff[a][b]<='Z') buff[a][b]=buff[a][b] - 'A' + 'a'; b--; for(c=0; b>=0; b--, c++) word[a][c]=buff[a][b]; for(b=0; buff[a][b]!='\0'; b++, c++) word[a][c]=buff[a][b]; word[a][c]='\0'; } printf("Your unsorted list of words\n"); for (e=0; e<10; e++) printf("%s \n",word[e]); return 0; }
