Write C programs to compare the execution time & compilation time for all the four storage classes variables

Variable Storage Class tells us:

1. Storage (location)
2. Default Initial Value of the variable
3. Scope of the variable
4. Life of the variable

1. Storage: Where the variable would be stored.

2. Default Initial Value: What will be the initial value of the variable, if initial value is not specifically assigned. (i.e. the default initial value)

3. Scope: What is the scope of the variable: i.e. in which functions the value of the variable would be available.

4. Life: What is the life of the variable: i.e. how long would the variable exist.

Automatic Storage Class Variable

Output:

0.293000

Register Storage Class Variable

Output:

0.053000

Static Storage Class Variable

Output:

0.282000

External Storage Class Variable

Output:

0.305000

So the Winner is Register Storage Class
