The difference between while structure and do structure for looping is--

In while statement the condition is tested at the end of first iteration

In do structure the condition is tested at the beginning of first iteration

The do structure decides whether to start the loop code or not whereas while statement decides whether to repeat the code or not

In while structure condition is tested before executing statements inside loop whereas in do structure condition is tested before repeating the statements inside loop

 ( and )

Question No: 11
      
Which of the following is not a reserve keyword in C++?

Mutable

Default

Readable

Volatile

Question No: 12

Identify the correct statement regarding scope of variables.

Global variables are declared in a separate file and accessible from any program.

Local variables are declared inside a function and accessible within the function only.

Global variables are declared inside a function and accessible from anywhere in program

Local variables are declared in the main body of the program and accessible only from functions.

Question No: 13

Both the inputs are stored in that variable

The second input overwrites the first one

The second input attempt fails since the variable already got its value

You can not use same variable for two getline statements
