I need someone to give me the best solution on using a Static variable and a boolean function to keep count of how many times a user made an invalid input in my program

This is such a simple requirement that all solutions are likely to be very similar in composition. Selecting the "best" will depend on your definition of best. As you are aware a static variable when included in the body of a loop for example is only referred to when within the first iteration of the loop so.....
for( ; ; )
"enter an integer less than 50 or greater than 500 (-99 to quit)"
enter integer n
while(n)
static count =0
if(n>=50 && n <=500)
count++
if(n=-99)break
"you entered " count " integers outside the range"
All you have to do now is turn the while loop with a boolean condition into a function of your choice. some condensation might also be appropriate.
