Parameters are the formal arguments of a function, as defined by the function. When you pass arguments to a function, those arguments are assigned to the function's parameters, either by value or by reference, depending on how the parameters are declared in the function. The following example explains both:
void foo( int param )
{
// param is a by value parameter, which is a copy of the argument passed to it.
}
void bar( int& param )
{
// param is a reference parameter, which references the argument passed to it.
}
int main()
{
int arg = 100;
foo( arg );
bar( arg );
return( 0 );
}
Note that passing a pointer is the same as passing an int by value: the pointer's value is passed to the function, not the pointer itself. To pass a pointer by reference, you must pass a pointer to pointer and the function's parameter must accept a pointer to pointer.
You can have a function with no parameters.
the basic parameters of transmission lines are R,L,C and G...........
a. Functions can have only one parameter. b. The order in which the parameters are defined matters. c. Parameters can be passed to a function in any order. d. Parameters have no order.
There is no builtin function 'counta' in C.
Any model can be linear/nonlinear. Linearity can be in parameters or in variables. In Y=a+ b*x1 + c*x2 + d*x3 the model is linear in both parameters (b,c,d) and variables(x1,x2,x3) In Y=a+ (b+c)x1 + c*x2 + d*x3 the model is nonlinear in parameters (b,c,d) and linear in variables(x1,x2,x3) In Y=a+ bx1 + c*x2*x3 + d*x3 the model is linear in parameters (b,c,d) and nonlinear in variables(x1,x2,x3) In Y=a+ bx1 + c*x2*x3 + exp(b+d)*x3 the model is nonlinear in parameters (b,c,d) and nonlinear in variables(x1,x2,x3)
Random example, function with two parameters: int main (int argc, char **argv) {...}
Manipulators are functions that change the formatting parameters on character streams.
int min (int a, int b, int c) {if (a
You can have a function with no parameters.
Is quite common. Example: int main (int argc, char **argv) { printf ("Number of parameters is %d\n", argc-1); return 0; }
I won't tell you, but maybe this example helps: int myfunction (int param1, long param2, short param3)

b+b+b+c+c+c+c =3b+4c
c + c + 2c + c + c = 6c
b + b + b + c + c + c + c = 3b + 4c
