The replace does not search anything. You must tell the exact position that you want to modify.
http://www.cplusplus.com/reference/string/string/replace/
Furthermore, it replaces only one position.

If you want to replace each 'a' with '1', then look at each character in turn:

for ( auto & c : nume ) {
  if ( 'a' == c ) c = '1';
}
