I'd like to know how the following programme on pointer written in C can be written in C#, especially how to use the keywords in the C programme like &i and *p in C#. Please clarify.
#include <stdio.h>
void f(int *p, int *q)
{
p = q;
*p = 2;
}
int i = 0, j = 1;
int main()
{
f(&i, &j);
printf("%d %d \n", i, j);
return 0;
}Jump to PostThis is presumably all about passing params as references rather than values (the default in C#)
To pass a parameter as a reference use therefkeyword.

The function f appears to put the value 2 into the second argument.
You can test that out as need be. No conversion appears to be required as I would toss function f and set j to 2. Done.
