C++ homework exercise:

Remove leading and trailing blank spaces from a map.

Write a C++ function prototyped as

void blanksOut(map & data);

Function blanksOut takes a map. It removes all leading and trailing blanks from the string values in the map. Function blanksOut must not add or remove any keys from the given map. For example,

map m;

m[33] = x y ;

m[40] = aaa;

m[51] = zzz;

blanksOut(m);

cout << m[33] << endl; //prints x y

cout << m[40] << endl; //prints aaa

cout << m[51] << endl; //prints zzz

How should this be done?

Thank you for any help.
