Explanation- Answer is, option four i.e Indicates that a variable's memory space is allocated upon entry into the block. “auto” variables are declared at the start of a program’s block i.e in the curly braces ( { } ). Memory is allocated automatically upon entry to a block and freed automatically upon exit from the block. The scope of automatic variables is local to the block in which they are declared, including any blocks nested within that block. For these reasons, they are also called local variables. No block outside the defining block may have direct access to automatic variables (by variable name) but, they may be accessed indirectly by other blocks and/or functions using pointers. Automatic variables may be specified upon declaration to be of storage class auto. However, it is not required to use the keyword auto because by default, storage class within a block is auto.

Answer is wrong Fourth option is the best description of auto! Sam 06-21-2014 03:49 AM

Auto specifier in C I find the given "correct" answer to be vague and missing the point. The fourth answer is closer to the meaning, though incomplete. An automatic ("auto") variable is a variable which is allocated and deallocated automatically when program flow enters and leaves the variable's context (e.g., function or block). Generally, all local variables are "auto" by default. gds 05-18-2014 03:15 AM

Auto specifier in C - auto storage-class specifier - It declares an automatic variabl which has a local lifetime. Aparna 07-5-2013 06:33 AM
