Answer:
c. StringBuilder
Explanation:
An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing, and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.
Answer:
The function definition to this question can be given as:
Function definition:
void printAttitude(int x1) //define function printAttitude.
{
//nested else-if statements
if(x1==1)
//if block
cout<<"disagree"<<endl;
//message
else if(x1==2)
//else if block
cout<<"no opinion"<<endl;
//message
else if(x1==3)
//else if block
cout<<"agree"<<endl;
//message
else
cout<<" ";
}
Explanation:
In the above method definition firstly, we define a method that is "printAttitude". In this method, we pass an integer variable that is "x1". This function does not return any value because its return type is void. In this method, we use nested else-if statements. The description of these conditions can be given as:
- In the if block we check the variable x1 value is equal to 1 If this condition is true. It will print "disagree" otherwise it will go to else-if block.
- In the else-if block, we check the variable x1 value is equal to 2 if the condition is true. It will print "no opinion". otherwise, we will go to another else-if block.
- In this block, we check the variable x1 value is equal to 3 if this condition is true. It will print "agree".otherwise it will go to else block.
- In the else block it will print nothing.

The answer to this question is given below in the explanation section.
Explanation:
Almost all app that is doing online business integrated third party payment gateway and login/services. But some apps, don't integrate the third party login/signin services such as go ogle or face book login/sign in services.
But in the context of this question, for a parking payment app, upon reservation of parking space, the pay option connects a user to a third party/external gateway. This gateway will accept payment from the user and upon confirmation of payment, the parking space will get reserved.
so the correct option to this question is:
While the other options are incorrect because:
The sign-in option does not connect the user to a third pay/gateway in case if the app has self-registration and sign-in functionality. Rate and Time remaining are features of the app that does not force the user to connect third-party gateway.
