[FEATURE] Add character input to simc

[Chasmiccoder]

So far, simc deals with strings properly, but it still does not have support for C characters.
Implementation of characters:
simc code -
var c = input( "Enter a character: ", "c" )
print( c )

Corresponding C code -
char c;
printf( "Enter a character: " );
scanf( " %c", &c );
printf( "%c", c );

Note how there is a space in the scanf( ) statement in the C code. This is because if the previous line has a
newline character ( '\n' ), then scanf( ) will consume it immediately. This is why the space needs to be there.
