Read a $2-$character string from input into variable inputString. Declare a Boolean variable isValid and assign isvalid with true if inputString contains an uppercase letter. Otherwise, assign isValid with false

Ex: If the input is D$1,$ then isValid is assigned with true, so the output is:

Valid string

Ex: If the input is $8,$ then isvalid is assigned with false, so the output is:

Invalid string

Note: Use getline $($cin$,$ inputstring$)$ to read the entire line from input into inputString. $($I need the answer in C$++)$
