Answer:
Handle the exception in a catch block or throw the exception to the method that called this method.
Explanation:
The try and catch statements occur in pairs. The try statement allows the user to define a block of code to be tested for errors while it is being executed.
The catch statement allows the user to define a block of code to be executed, if an error occurs in the try block.
If an exception is checked by a method, the method either handles the exception in a catch block or throw the exception to the method calling it.

Answer:
Correct answer is option (2) that is "return".
Explanation:
In any programming language, a variable name can be made up of letters (lower and upper case) and digits. we can also use "_" underscore character for declaring the variables but we cannot use any special character like “$”.We cannot use digits in the beginning of variables name. And we also cannot use reserved keywords of the language like "new","return","while" etc. There should not be space between the variable names. Options 1, 3 and 4 are not violating any of these properties. But in option (2), "return" is a reserved keyword. That is why it is not a valid variable name.
Some example of valid variables name:
foo
BAZ
Bar
_foo42
foo_bar
Some example of invalid variables name:
$foo    ($ not allowed)
while   ( keywords )
2foo    (started with digit)
my foo  (spaces )

Answer:
#include<stdio.h>                        //header file
int main()                                      //main function
{
float num;                                   // variable declaration
printf("Enter a number to test:\n");   // getting variable for test
scanf("%f", &num);
if (num>45.6)                                    //Testing weather greater or smaller
printf("\n %f is greater than 45.6", num);  // Result if greater
else
printf("\n %f is not greater than 45.6", num);  // Result if smaller or equal
return 0;
}
Explanation:
- First of all , a variable will be declared in float (data type ). 
- User will input data in variable.
- The variable will be compared using logical operator with 45.6 
- If it is greater, A phrase will be passed that number is greater than 45.6
- Else if the number will not greater the phrase will say that the number is not greater than 45.6
