1.In c++,I/O is performed using I/O operators instead of I/O
functions.
2.In c,when a function takes no parameters,its prototype has
the word void inside its function parameter list.But,in
c++,the void is optional.
for instance,char f1(void)[in c]
char f1()[in c++]

3.In c++,local variables can be declared anywhere but in
c,local variables can be declared only at the start of a block.
