Output:

enter N:3

enter integer value:1

enter integer value:2

enter integer value:3

 output:

1

2

3

 a=0x9f0eb0

 a=0x9f0eb0

enter float value:1.2

enter float value:3.4

enter float value:5.6

 output:

1.2

3.4

5.6

 b=0x9f0eb0

 b=0x9f0eb0

enter char value:a

enter char value:b

enter char value:c

 output:

a

b

c

 c=10425008

 c=10425008
