Pass by Reference in C

[Humble]

hmmm.. C does not have “strict pass by reference” concept. Even-though everyone says it exist , in reality “pass by reference” does not exist in C .

pass by reference is an illusion 🙂 .. That said, ‘pass by reference” examples are mainly carved with the help of below format.

int f1(int *p)
{
.....
return ...
}

int main()
{
int i = 5;

f1(&i)
}


Here the actual passing of argument to f1() happens with "pass by value" , how-ever we tend to say "it is pass by reference" being the address is passed to f1.. Here the "address" is passed/copied to "p",so again its pass by value..
