Doubt in understanding this problem

#1

Why do we need a loop. What task do I have to repeat?

#2

hello @yashsharma4304

first u will given a character.
this character can be some operator if it is operator then read two operands ,print the result and continue the same procedure again (reading character then operator)

if character is x or X then simply stop execution.

if character is neither operator nor x/X then for such case print invalid operation and repeat the procedure.

check sample example for better understanding

#3

Ok so the answer is printed in 1 case when the operator is given as input And program will stop only in 1 case when x or X is given otherwise we have to repeat the task. Right?

#4

yeah correct… …
