D tab that is the key you would need to use in order to do that
Answer:

Explanation:
Given

Required
The result when
and
Analyzing the given instruction
a*=(++a)/(6)+(b++3)
Single out and solve the expressions in bracket
(++a) = a -- When the ++ operator appears before an operand, it is called pre increment. meaning that the operation will be done before the operand will be incremented.
So: in this case: ++a = a

The operator, as used in that statement is the same as: b + 3.
So:





The above expression is calculated as:

So:

Answer:
Explanation:
The following code is written in Java. It asks the user for an input and saves it in a String variable. Then it loops through all the characters in the string and counts the spaces. Finally, it prints the total number of spaces in the String.
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter Line Now:");
String userInput = in.nextLine();
int spaceCount = 0;
for (int x = 0; x < userInput.length(); x++) {
if (userInput.charAt(x) == ' ') {
spaceCount++;
}
}
System.out.println(spaceCount);
}
