Question

Int fun( char *str1)

{

char *str2=str1;

while(* ++str1); || here it accesses the data then increments or increments and then checks the data?

return(str1-str2);

}

main()

{

char * str = "Ravindran";

printf("%d",fun(str));

}

a)10

b)9

c)8

d)random number

Answer 1

In while(*++str); see both ++ and * is having the same precedence but assosciativity is from RIGHT to LEFT so first it will increment and then check the data and loop will terminate when it will find NULL.
