Volatile is to inform the compiler that not to optimise
code.
for ex:
int a = port1;
int b = port1;
int c = port1;

compiler may convert it as
int a=b=c=port1;

so avoid it , u have to use volatile keyword.

Basically, it is a type qualifier.
a volatile data type is used at optimizer level.
Generally, in the embedded coding, When the optimizer is Set
on "favor size". The data type declaration as volatile
declares to compiler that the value of this data type can
change beyond the program flow(like interrupts.
Otherwise if the optimizer is enable, the program malfunctions.

Function shall sum members of given one-dimensional array. However, it should sum only members whose number of ones in the binary representation is higher than defined threshold (e.g. if the threshold is 4, number 255 will be counted and 15 will not) - The array length is arbitrary - output the results to the stdout
