Табулирование функций (Си)(Geany желательно)

[Alexey22rus]

Помогите пожалуйста, для зачета сделал программу, но она работает не так, как хотелось бы, подскажите ошибочку пожалуйста...
Само задание:


Моё решение:
main.c

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

int tab(float , float , float , float(*) (float));
float Rainmeter(float );

int main (int argc, char *argv[]){
	float a,b,h;
	printf("Vvedite otrezok ot a do b i shagom h\n");
	scanf("%f %f %f",&a,&b,&h);
	printf("%f %f %f\n",a,b,h);
	if (tab(a,b,h,Rainmeter)==0 ){printf("Programma zavershilas uspeshno");}
	return 0;
}

lab.c

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

int tab(float a, float b, float h, float(*f) (float)){
 float x;
 FILE *fout;
	if ((fout=fopen("Data.dat","w"))==NULL){
			printf ("\n Ne mogu otkrit %s\n","Data.dat");
			return 1;
			}
 	 for (x=a; x<=b; x=x+h){
 		 printf ("%f %f \n",x,(*f)(x));
		fprintf(fout,"%f %f \n",x,(*f)(x));
 	 }
return 0;
}

my2.c

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#define V 1
#define V0 2
#define a 3

float Rainmeter(float t){
	float S;
	S=((V*V)-(V0*V0))/(2*a);
//	printf ("Respons %f\n",F);
	return S;
}

Библиотека:
Makefile

# This is an Makefile example.
# make is useful utilite to easyly build executable file(s)
# from source files. If you have file named Makefile in
# current directory you can just type 'make' to create
# final executable files using libraries and so on.
# You can type something similar to 'make clean' to do cleaning
# your directory from old files or other things.
# Please, use 'man make' to get more information.

# First, we define some macros (it may be omitted)
# for example, the source files of our project
# SRC	= myfunc.c
# the object files
# OBJ	= myfunc.o
LIB	= libMy.a
LIBSRC = lab.c my2.c
LIBOBJ = lab.o my2.o
# MYLIB =	libMy.a
         
# the files what we are going to archive 
#ARCHIVE = $(SRC) Makefile
# the file where we want store the archive.
#ARCH_FILE = labs
# This is strangle way to get short library name from long one.
#LIBNAME	= `expr $(LIB) : '...\(.*\)..'`

# $1 2>$x.err
# -o $x $x.o -lsimul -L/home/zhur/SIMULATE/FORT>>$x.err

FFLAGS	= -Wall -c
# Next, we define the targets and their dependences.
# To get a correct target we need the up-to-day dependencies.
# The make utilite automaticaly cheks it and remades only
# files that were be changed after last building the target.
# The first target will be made in you typed 'make'.
# In this example the next line may be omitted or
# additional dependences may be set, for example
# all: lab1 lab2 ...
all:
	gcc $(FFLAGS) $(LIBSRC)
	ar vr libMy.a $(LIBOBJ)

# Other targets will be made (or remade) only if we specify
# the target name in command line or if target depends on
# other targets which should be remade.
# After this line you can put shell commands.
# NOTE: <TAB> must be put before command (not SPACES).
#nmslib:	$(LIB)
#	gfortran $(FFLAGS) $(LIBSRC)
#	ar vr libNMS.a $(LIBOBJ)

# The 'lab1' target needs up-to-date library 'libmy.a' (see macros
# definitions at the top of the file). The 'libmy.a' target
# needs up-to-date objects files. Note that 'make' utilite knows
# how to make library from object file (it even uses different commands
# 'a' or 'r' depend on existion object file in library) and
# object file from FORTRAN file. We remove object files 
# after putting in library to free disk space.
$(LIB): $(LIB)($(LIBOBJ))
	rm -f $?

clean:
	rm -f *.o lib*.a

# 'make tgz' used to make archive file. This file will be packed
# to reduce disk space usage. You must have path '/usr/local/bin'
# in your PATH environment variable (see your $HOME/.profile).
#tgz:
#	tar cvf $(ARCH_FILE).tar $(ARCHIVE)
#	gzip $(ARCH_FILE).tar
#	mv -f $(ARCH_FILE).tar.gz $(ARCH_FILE).tgz

После чего ввожу значение a,b и шаг h, но почему-то он просит ввести 4-ое значение.И далее мне выдает примерно такое:

1.0000000 0.0000000
2.0000000 0.0000000
3.0000000 0.0000000
4.0000000 0.0000000
5.0000000 0.0000000

Хотя во втором столбце должно быть не это(не знаю что должно быть, но точно не это).
Помогите пожалуйста решить.

Кстати в какой программе можно программы на Си писать на виндовсе? А то в универе Geany стоит, но качаю я какую-то левую /problem. Да и система там другая
