PJ 5 – Simple CalculatorPlease write a C++ program that can perform the following 6 operators for 2 numbers: N1 and N2. Youneed to prompt the user to enter a number, an operator, and another number. To simplify your program,please declare N1, N2, and result as double-floating numbers, and operator as char. Please see the sampletest below to design your application program properly. This program is a simple calculator for users toenjoy. Please let your program keep running to accept more data for the next operation until the operatorreceived is @. In other words, the operator @ is the only way to stop your program and thank the user.6.Thevalid operators for this simple calculator are as follows:1. + for addition of N1 and N2. Therefore, result = (N1 + N2).- for subtraction of N2 from N1. Therefore, result = (N1 – N2).3. * for multiplication of N1 with N2. Therefore, result = (N1 * N2).4. / for floating-point division of N1 by N2. If N2 is 0, please say “The second number cannot be zero",else result = (N1 / N2).5. ^ for power N2 with base N1 (i.e., N1N2). Therefore, result = pow ( N1 , N2 ). // power functionpow(N1, N2) is a function call to compute N1 power N2.6. % for integer division remainder (i.e., modulus) of N1 by N2.

Please write a C++ program that can perform the following 6 operators for 2 numbers: N1 and N2. You
need to prompt the user to enter a number, an operator, and another number. To simplify your program,
please declare N1, N2, and result as double-floating numbers, and operator as char. Please see the sample
test below to design your application program properly. This program is a simple calculator for users to
enjoy. Please let your program keep running to accept more data for the next operation until the operator
received is @. In other words, the operator @ is the only way to stop your program and thank the user.

The
valid operators for this simple calculator are as follows:
1. + for addition of N1 and N2. Therefore, result = (N1 + N2).
- for subtraction of N2 from N1. Therefore, result = (N1 – N2).
3. * for multiplication of N1 with N2. Therefore, result = (N1 * N2).
4. / for floating-point division of N1 by N2. If N2 is 0, please say “The second number cannot be zero",
else result = (N1 / N2).
5. ^ for power N2 with base N1 (i.e., N1N2). Therefore, result = pow ( N1 , N2 ). // power function
pow(N1, N2) is a function call to compute N1 power N2.
6. % for integer division remainder (i.e., modulus) of N1 by N2. If N2 is zero, please
say “The second number cannot be zero", else result = ( int(N1) % int(N2) ).
int(N1) is a function call to convert N1 to an integer. % operator accepts only two integers.
2.
7. @ for stopping this calculator after printing a friendly thank-you message.
8. Otherwise, please say “Sorry, the operator
is not valid!". // Please show this invalid operator.
Your test case #1 must look exactly as follows including the data. You must also do test case #2 and test
case #3 with different sets of data. Each of your test case must cover all the 6 valid operators (at least once
for each) plus an invalid one, Each test case or test run must begin with a welcome message, and must end
