in the first case it is pointer to a constant (i.e the
address can be changed ,where as the content/value in that
address cannot be changed).
In the later case it is a constant pointer (i.e the address
cannot be changed ,where as the content/value in that
address can be changed).

Answer / vignesh1988i
as for as i know.....
1) const char * :
here the character pointer is a constant which can point to
oly one character type memory location throught the program.
2) char * const :
hrere the pointer is not a constant , the character variable
used after it will be constant.. in that variable we cant
make any changes... but in pointer we can make
thank you

Write the program with at least two functions to solve the following problem. The members of the board of a small university are considering voting for a pay increase for their 10 faculty members. They are considering a pay increase of 8%. Write a program that will prompt for and accept the current salary for each of the faculty members, then calculate and display their individual pay increases. At the end of the program, print the total faculty payroll before and after the pay increase, and the total pay increase involved.
main() {int i=5; // line 1 i=(++i)/(i++); // line 2 printf("%d",i); // line 3 } output is 2 but if we replace line 2 and line 3 by printf("%d",i=(++i)/(i++)); then output is 1. Why?
