Answer :

The value if process is 0 !

Explanation:

The function 'process' has 3 parameters - 1, a pointer to
another function 2 and 3, integers. When this function is
invoked from main, the following substitutions for formal
parameters take place: func for pf, 3 for val1 and 6 for
val2. This function returns the result of the operation
performed by the function 'func'. The function func has two
integer parameters. The formal parameters are substituted as
3 for a and 6 for b. since 3 is not equal to 6, a==b returns
0. therefore the function returns 0 which in turn is
returned by the function 'process'.

main() { void swap(); int x=10,y=8; swap(&x,&y); printf("x=%d y=%d",x,y); } void swap(int *a, int *b) { *a ^= *b, *b ^= *a, *a ^= *b; }

There is a lucky draw held every day. if there is a winning number eg 1876,then all possible numbers like 1867,1687,1768 etc are the numbers that match irrespective of the position of the digit. Thus all these numbers qualify fr the lucky draw prize Assume there is no zero digit in any numbers. write a program to show all the possible winning numbers if a "winning number"is passed as an arguments to the function.
