parameter-passing

Consider the following C program: #include< stdio.h > void fun1(char *s1, char *s2){ char *tmp; tmp = s1; s1 = s2; s2 = tmp; } void fun2(char **s1, char **s2){ char *tmp; tmp = *s1...

In which one of the following cases is it possible to obtain different results for call-by-reference and call-by-name parameter passing methods?

Indicate the following statement true or false: Although C does not support call by name parameter passing, the effect can be correctly simulated in C.
