Order of execution of command

#1

does the command gets executed from left to right or right to left?

#2

hey mayank, it will be left to right.

ans= factorial(n)/(factorial®*factorial(n-r));

first factorial(n) is called
than (factorial® is called
and than factorial(n-r)

Please help me understand above link’s code then.

Hii mayank

Your doubt is genuine as anybody gets confused in such cases. Remember that when we are storing value in a variable or returning it,then statements go left to right.
If we are doing a cout<< then statements are executed right to left.

If you still have doubt then you can check for b=a++ + a++. It will be clear to you.

#6

I get what you say but I’m unable to understand output value for ‘b’.

#7

In the case I told you the value of b would be 3 . Is this your question?

#8

but the value is 5. also look that a=;

#9

a=1; b=++a + a++; from left to right execution, a is first incremented to 2 and later it is also used as 2(for a++), so the output should be 4.

#10

I was telling 3 as the answer of this.

For your doubt, as you are assigning answer to b it is because unary operator will have higher precedence
