Hi ,
I included math.h file in two of my .c files and it gives me an error
| Quote: | | Function definition different from previous definition y != float |
when I delete one of the two includes it's works perfectly but when there is more than one in my program it's writing the above error
what should I do in order to fix it?
Thanks

Delete all of them except one:
Include math.h in your main source file, and put it above any other
#include statements for other source files. |

If you look at the file, it shouldn't matter if you load it twice. The file tests right at the start for 'math_h' being defined, and if it is, the rest of the file doesn't load. If not, it defines this, and loads.
A number of possibilities exist:
1) The file has been modified.
2) A second file with the same name is present.
3) A very old version.
4) Something else is modifying the math_h define.
etc...
