Answer:
Three ways to increase the value of variable are given below. To eleborate the answer, I am taking a variable x that need to be increase.
- x=x+1
- x++
- x+=1
Explanation:
There are three ways to increase the value of variable.
1. x= x+1
In this case, each time value of x (variable) is incremented and stored in that variable. This equation increase the value of x by 1 each time. For Example
if x=1
then in first iteration
x= x+1 = 2;
If we want to increase the value of x by more than 1, we can add that value with x, as x+2, x+3 and so on.
2. x++
This will increment the value of x by 1. If we use this equation multiple time in program, each time it will increase 1 in value of x.
3. x+=1
This also works same as equation 1. It will increment 1 in this form and can be changed with 2, 3 and so on.
user_in = str ( input ("Please enter a phrase: " ))
def reverse_str (string):
e = 0
for e in range (len (string)):
x = -1
print string[x]
x += (len (string))
Answer:
The solution code is written in C++
- bool STATUS = true;
- bool alternator ()
- {
- if(STATUS){
- STATUS = false;
- return true;
- }else{
- STATUS = true;
- return false;
- }
- }
Explanation:
We need a global variable to track the status of true or false (Line 1).
Next, create the function alternator (Line 2) and then check if current status is true, set the status to false but return the previous status boolean value (Line 5-6). At the first time of function invocation, it will return true.
The else block will set the STATUS to true and return the false (Line 7-9).
