(string process, fgets, scanf, neat utilization of switch clause)

simple problem, simple code.

#include <cstdio>

#include <algorithm>

#define MAXLEN 22

char password[MAXLEN];

int main() {

    //freopen("input.txt","r",stdin);

    int nc,nv,vcnt, invalid;

    char *p;

    while(scanf("%20s",password)==1 && strcmp(password,"end")!=0) {

        nc=nv=vcnt=0; invalid=0;

        p=password-1;

        while(*++p) {

            switch(*p) {

            case 'e':

            case 'o':

            case 'a':

            case 'i':

            case 'u':

                ++vcnt; ++nv; nc=0; break;

            default:

                ++nc; nv=0; break;

            }

            if(*p==*(p+1) && *p!='e' && *p!='o') { invalid=1; break; }

            if(nc>2 || nv>2) { invalid=1; break; }

        }

        if(invalid || vcnt==0) printf("<%s> is not acceptable.\n",password);

        else printf("<%s> is acceptable.\n",password);

    }

    return 0;

}
