    charFreq[index]++;

}

cout<<"\n****************************************\n";

cout<<"\nSentence : "<<mystr<<endl<<endl;

cout<<setw(12)<<"Character"<<setw(12)<<"Frequency"<<endl<<endl;

for(int i=0;i<26;i++){

    if(charFreq[i]!=0){

        cout<<setw(6)<<char(i+'a')<<setw(10)<<charFreq[i]<<" times \n";

    }

}
