Write a class named ParkingMeter containing: An instance variable named timeLeft of type int, initialized to 0. A method named a

dd that accepts an integer parameter. If the value of the parameter is equal to 25, the value of timeLeft is increased by 30; otherwise no increase is performed. add returns a boolean value: true if timeLeft was increased, false otherwise. A method named tick that accepts no parameters and returns no value. tick decreases the value of timeLeft by 1, but only if the value of timeLeft is greater than 0. A method named isExpired that accepts no parameters. isExpired returns a boolean value: true if the value of timeLeft is equal to 0; false otherwise.

(5 pt.) The name of a variable in the C programming language is a string that can contain uppercase letters, lowercase letters,
lilavasa [31]

Answer:

The different variable in C is 21213316700.

Explanation:

Given value:

Total value  = letters + underscore value

Total value  = 52 + 1

Total value =53

choice for first character = 53 letters +10 digits

first character = 63

choice for remaining characters

So,

Variable number With one 1 character = 53

Variable number With 2 character  = 53 × 63

Variable number With 3 character = 53 × 63²

Variable number With 4 character  = 53 × 63³

.

.

.

Variable number With 7 character  = 53 \times  63^{7}

Total difference variable = 53 + 53 × 63+ 53 × 63²+ 53 × 63³+....+ 63^{7}

Total difference variable = 53(1 + 63 + 63²+ 63³+ .... + 63^{7})

Formula:

1+x+x^2+x^3+x^4+........x^n\\\\\Rightarrow  \frac{x^{(n+1)} -1}{x-1}

Total difference variable

53 \times \frac{63^{7+1} -1 }{63-1}\\\\53 \times \frac{63^{8} -1 }{63-1} \\\\ \therefore 63^8 = 2.48 \times 10^{14}\\\\53 \times \frac{2.48 \times 10^{14} -1  }{62}\\\\53 \times \frac{1.48 \times 10^{14}}{62}\\\\21213316700
