$$ A session with the program:

$$

$$

$$ Enter operation code: i

$$ Enter part number: $528$

$$ Enter part name: Disk drive

$$ Enter quantity on hand: $10$

$$

$$ Enter operation code: s

$$ Enter part number: $528$

$$ Part name: Disk drive

$$ Quantity on hand: $10$

$$

$$ Enter operation code: s

$$ Enter part number: $914$

$$ Part not found.

$$

$$ Enter operation code: i

$$ Enter part number: $914$

$$ Enter part name: Printer cable

$$ Enter quantity on hand: $5$

$$

$$ Enter operation code: u

$$ Enter part number: $528$

$$ Enter change in quantity on hand: $-2$

$$ Enter operation code: s

$$ Enter part number: $528$

$$ Part name: Disk drive

$$ Quantity on hand: $8$

$$

$$ Enter operation code: p

$$ Part Number$$ Part Name$$ Quantity on Hand

$528$ Disk drive$8$

$914$ Printer cable$5$

$$

$$ Enter operation code: q

$$

$$

Steps:

$$ The program will store information about each part in a structure.

$$ The structures will be stored in an array $($global$)$ named inventory.

$$ A global variable named num$\_$parts will keep track of the number of parts currently stored in the array.

$$ An outline of the program$$s main loop:

$$ for $($;;$)\{$

$$ prompt user to enter operation code;

$$ read code;

$$ switch $($code$)\{$

$$ case $\text{'}$i$\text{'}$: perform insert operation; break;

$$ case $\text{'}$s$\text{'}$: perform search operation; break;

$$ case $\text{'}$u$\text{'}$: perform update operation; break;

$$ case $\text{'}$p$\text{'}$: perform print operation; break;

$$ case $\text{'}$q$\text{'}$: terminate program;

$$ default:$$ print error message;
