Passing by value is where you pass the actual value (be it an integer, an array, a struct, etc.) to a function. This means that the value must be copied before the function is called and therefore the value in the caller cannot be modified within the callee. Passing by reference is where a reference/pointer to a value is passed to a function. The reference often takes up less space than copying the actual value (particularly when the value is a struct or an array) and allows you to manipulate the value in the caller within the callee.
Passing a single value to a function is often just a simple integer. But passing an array, character string or other data structure is typically "pass by reference", or in other words, the calling statement will 'point to' the place in memory where the data structure resides.When a function is called using a pointer to a data structure, both the calling environment and the called function are referencing the same data; any changes made to the data in the structure by the function will have changed the data that the original calling environment sees.However, when a value is passed to a function, the function creates it's own copy of the value, and can change it in any way without changing the original value.
Passing an argument by value means that the method that receives the argument can not change the value of the argument. Passing an argument by reference means that the method that receives the argument can change the value of the incoming argument, and the argument may be changed in the orignal calling method.
Both ++you and you++ have the same ending result. The variable you is incremented. The difference is that, if you use the combination in a larger expression, then you++ will have the initial value of you, while ++you has the incremented value of you.

The size (and value-range) of int is platform-dependent, whilst that of int32_t is fixed.
To some people, there is no difference.. both mean dying. To others, the difference is that "passing away" means simply dying and "passing on" refers to going to the afterlife.

Yes, there is a difference between passing out and falling asleep. Passing out is a sudden loss of consciousness, often due to a medical issue or injury, while falling asleep is a natural and gradual process of entering a state of rest.
Surplus value is the difference between the value that workers produce and what they are paid in wages.
the same as the difference between ct and k
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.
There is no difference because they are of equal value

The difference is the PLACE VALUE is the number in standard form and the VALUE is the name of the place spot the number is in.
