in line 39 , the program state the error : "overflow in implicit constant conversion "
correct for me please, thank you

10000000 is an integer constant, and is probably too large to be represented in the int type supported by your compiler. [That presumably means you are using 16 bit compiler].

Also, as someone said in your other thread, "if ( 4000000 < ammwater < 10000000 )" does not test if ammwater is between 4000000 and 10000000. Refer that other thread and read the explanation of that.

I tried to count lines to see which one is line 39, and I managed it

case 'I' : case 'i ' :

Notice that second 'i ', do you see a difference between:

'i'
'i '

First is valid, second is invalid!
Change that first

Well spotted :)

sorry i DONT' KNOW WHAT YOU MEAN, you mean it was not my mistake right, and how to sove this problem .??

A 32-bit system can store from about -2 billion to 2 billion in an integer. Something like that, so 10,000,000 is within that range. A 16 -bit system can store some thing like -32,000 to 32,000 in an integer, so 10,000,000 is outside of that range. This line is incorrect regardless:

else if ( 4000000 < ammwater < 10000000 )

Change it to:

else if ( 4000000 < ammwater && ammwater < 10000000 )
