(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.
",password);
        else printf("<%s> is acceptable.
",password);
    }
    return 0;
}
