construct when you are initialising a group of variables. The last statement illustrates that it possible to actually do some calculations to arrive at the value which will be assigned to all three variables.
The program has no output,so compiling and executing this program will be very uninteresting. Since you have already learnt how to display some integer results using the printf function,it would be to your advantage to add some output statements to this program to see if the various statements do what you think they should do.
this would be a good time for a preliminary definition of a rule to be followed in
C. the data definition are always given before any executable statements in any program
block. This is why the variables are defined first in this program and in any C program. if you try to defined a new variable after executing some statements, the compiler will issue an error
