printf("The value of process is %d !\n
",process(func,3,6));

}

process(pf,val1,val2)

int (*pf) ();

int val1,val2;

{

return((*pf) (val1,val2));

}



func(a,b) int a,b; { return( a= (a==b) ); } main() ..

Answer / susie

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'.

You are given any character string. Find the number of sets of vowels that come in the order of aeiou in the given string. For eg., let the given string be DIPLOMATIC.
