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?
