Step 1: void fun(); This is the prototype for the function fun().
Step 2: fun(); The function fun() is called here.

Question :
The following program
main()
{ int abc();
abc();
(*abc)();
}
int abc()
{ printf("come"); }
Step 1: void swap(char *, char *); This prototype tells the compiler that the function swap accept two strings as arguments and it does not return anything.
Step 2: char *pstr[2] = {"Hello", "GPLgtests"}; The variable pstr is declared as an pointer to the array of strings. It is initialized to pstr[0] = "Hello", pstr[1] = "GPLgtests"
Step 3: swap(pstr[0], pstr[1]); The swap function is called by "call by value". Hence it does not affect the output of the program.
If the swap function is "called by reference" it will affect the variable pstr.
Step 4: printf("%s
%s", pstr[0], pstr[1]); It prints the value of pstr[0] and pstr[1].
Hence the output of the program is : Hello GPLgtests
