Using Data Types and Type Coercion (Casts)

printf string [, exp1 [, exp2, ... ] ]

Print the value(s) of the speciﬁed expression(s) in the format

speciﬁed by the string, string. The printf command supports

all formats of the IRIX printf command except “%s.” For a

list of formats, see the printf(3S) reference page.

Using Data Types and Type Coercion (Casts)

You can use data types for type conversion (casting) by including the name

of the data type in parentheses before the expression you want to cast. For

example, to convert a character into an integer, use (int) to cast the value:

(dbx) print (int) ’b’

To convert an integer into a character, use (char) to cast the value:

(dbx) print (char) 67

’C’

This is standard C language type casting.

Displaying and Changing Program Variables

You can use the value of program variables in dbx expressions. You can also

change the value of program variables while running your program under

dbx control.

Qualifying Variable Names

You can use the same name for different variables multiple times in the same

program. For example, you can use a temporary counter named “i” in many

different functions.

During program execution, this potential ambiguity presents no problem.

The scope of each variable is local; space is allocated for it when the function

is called and freed when the function returns.
