Difference Between Normal Executable Statement and Printf Statement

[Praveen Chandra]

What is the Difference Between Normal Executable Statement and Printf Statement?

For example what the difference between i++ + ++i in normal executable statement
z=i++ + ++i;

and printf statement
printf("%d",i++ + ++i);

[Sandhya.Kishannag]

In executable statements we always require a constant to output the values where as in printf the constants required for output are readily available.Printf also allows to display contents of several variables in formatted output and also to provide text labels.


In above example if i=2 then

z=i++ + ++i gives output as z=7
printf("%d",i++ + ++i); gives output 7
