You pass arguments to functions because that is how you tell the function what you want it to do.

In this case sqrt is the function name, b is passed as its argument, and the return value is assigned to a.

Can a variable name can be passed to a value parameter in c plus plus?
No. Pass by value always receives a copy of the value being passed. Even if it were possible to physically pass a user-defined identifier into a function by value, the compiled code would not recognise the name since all identifiers are stripped out by the compiler and replaced with memory addresses. Strictly speaking, even pass by reference does not pass the variable name, as the function argument is simply an alias, an alternate but informal name, for the formal name you actually pass. In essence you are passing the memory address of the variable, rather the value of the memory address as you would with pass by value.
