The code shown below in the description runs here when I try it, but when I wrote it on code blocks it gave me 5 errors..
1. expected imitializer before '<' token. (line 19).
2. reference to 'pair' is ambiguous. (line 26).
3. expected primary-expression before double. (line 26).
4. expected ';' before 'double'. (line 26).
5. 'obj' was not declared in this scope. (line 27).
Any help please?
