Simple Game C++

Hello, i got a simple question, im making a C++ console game, and i got a whole function(void) for each map of the levels, and they look very similar. in the source code the functions have these names...

m1();
m2();
m3();
m4();

if you look the differences between each void you look it only changes a few times the char of each map, like char Map, char Map2 etc...

I want to make just a void for all maps, and that some other variable changes the Map each time a map is loaded......

Also i think it would work to put an int between a line like this

char Map"here should goes the int"[10][10];

that way i just change the int value in every map loading to make it work......

Thanks

BTW here is the whole source code....
