I am a beginner too, but try this: (Use #'s instead of a&Z)

#include <iostream>
using namespace std;

int main()
{
int sum = 0;
int number;
char ch;
do
{
cout<<"Please enter a number"<<endl;
cin>>number;

if(!(number>='1' && number<='100'))
sum = sum + number;
else
break;
cout<<"Do you want to enter another number(y/n)"<<endl;
cin>>ch;
}while(ch!='n');
cout<<"the total characters entered is "<<sum<<endl;
return 0;
}

We all start somewhere...

try changing the above loop to:

while (cout<<"Please enter a number"<<endl,cin>>number){
//or more simply
while (cin>>number){
sum+=number;
cout<<"Do you want to enter another:"<<endl;
cin>>ch;
if (ch !='n') break;
//I forget if you should use a cin.ignore to remove the newline
}

A more robust way of doing this would be to read the input as a string (or
char array) and parse it to extract the valid data (but maybe overkill.)

Of course, we all need enough sleep as well...
