While calling a function, if the arguments supplied are the original values it is called call by value.
e.g.
int sum(int a, int b)
{
return (a+b);
}
int main()
{
int a=10;
int b=20;
printf("Sum is %d",sum(a,b));
return 1;
}
In programming languages, call by value passes the value of a variable to a function, while call by name passes the name of the variable. Call by value evaluates the value before passing it, while call by name evaluates the value when it is used in the function.
You call it its value.
A value parted with is we call a Credit.
A value parted with is we call a Credit.
In call by value, the value of the argument is passed to the function, while in call by name, the expression for the argument is passed and evaluated each time it is used in the function.
The value of a call option on maturity is equal to its intrinsic value.For instance, a call option with a strike price of $10 on maturity and its underlying stock being at $15 will have a value of $5, which is its intrinsic value.

when the function is call by value,u are making any changes in formal parameter does not reflect the actuasl parameter.
By default, a copy of the argument's value is passed into the parameter variable. This is "call by value" semantics, and the called function can do whatever it wants with the parameter, but it cannot alter the original copy. Sometimes, in C and C++, you can pass the address of the value instead. This is "call by address" semantics, but the called function must be designed to handle it - in this case, the called function can alter the original value. (Actually, it is always "call by value" - what we call "call by address" is simply passing the value of the address, a subtle distinction which is important to understanding the language.)
Yes.
Call by value essentially passes a copy of an object's value whereas call by reference essentially passes the object itself. Pass by reference is the preferred method whenever possible as call by value will automatically invoke the object's copy constructor, which is often unnecessary, especially if the object is not affected by the function call (pass by constant reference).
Can I get the answer on line, or do i HAVE to call in? Where can i GET the cash value for my policy?
