In c++ it show compression like x<=y<=z hv no mathematical meaning, what do i do to implement this type of conditions by if?

Answer 1

Dear Shuvam,

Expression x<=y<=z implies that x<=y and y<=z, thus it can be implemented in following manner

if (x<=y && y<=z){
//your code
}

I think this will help

Answer 2

You must write "x<=y && y<=z".
[EDIT:] && is the boolean operator that means "and".

Answer 3

The above expression is mathematically okay. But when it comes to programming, such expressions need to be broken into binary expressions and combined using logical operators.

Let us examine it

x<=y<=z say that x is greater than or equals to y and y is greater than or equals to z. Here we get two expressions
x <= y
y <= z

Now we need to combine them. Since both have to be evaluated as true to get processed, we will perform and operation on them and in C++ it is done by && operator.

Answer 4

No dear these cannot be use in switch clause as it evaluate expression only against fixed values

Answer 5

Let me implement by this

Answer 6

By the way can u explain how & & helping it out?

Answer 7

It work thank you

Answer 8

Can i use those relation operators with switch cases?
