Answer:
The method definition to this question can be given as:
Method definition:
public void clear(int[] arr, int num) //define method clear.
{
if (num == 0) //if block
{
return 0; return value.
}
else //else block
{
arr[num - 1] = 0; //assign value in arr.
return arr[]; //return value.
}
}
clear(arr, num - 1); //calling
Explanation:
The description of the above method definition as follows:
- Firstly we define a method that is "clear" that does not return any value because its return type is "void". This method accepts two integer variables that are "arr[] and num" where arr[] is an array variable and num is an integer variable.
- Inside a method, we use a conditional statement in if block we check that num variable value is equal to 0. if this condition is true so, it will return 0 otherwise it will go to else block in else block it will assign value in variable arr[num-1] that is "0" and return arr value.
Answer:
Case
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
A Select Case statement can be defined as a conditional statement that avails software developers or programmers the ability to test a variable by comparing it with a list of values.
In a Select Case statement, each variable is referred to as a Case.
Generally, when a Select Case statement executes, the value of the test expression is compared with the values that follow each of the Case keywords.
Ex:
FOR Count= 1 TO 50
.......................
Body
......................
NEXT
Next keeps incrementing count by 1
