Becouse it's beging. I'm study recently in university this language C. and i'm mistaken it's C++. sorry, but thanks for all help. it's relly very fast ansver

I can do it

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


float menor(float lista[], int n);
float maior(float lista[],int n);


void main()
{
	int i,g;
	int b1,b2,b3,b4,b5,b6,b7,b8,b9;
	int frab[10]={0};
	float frel[10]={0};
	float inf, sup, p, a, c;
	int nlinhas;

	FILE *pfile;  // Apontador para uma estrutura de um ficheiro
	char nome_ficheiro[]= {"C:\\Users\\Vladimir\\Desktop\\(1)\\Ficha1\\DOC\\Teste.txt"};  // String com o nome do ficheiro
	float * valores;// Apontador para o Array dinamico que guarda os valores lidos do ficheiro

	pfile= fopen(nome_ficheiro, "r");

	if(pfile == NULL)
		printf("ERRO NA ABERTURA DO FICHEIRO");
	else
	{
		fscanf(pfile, "%d", &nlinhas);
		valores = new float [nlinhas];



		for (i=0; i<nlinhas; i++)
		{
			fscanf(pfile, "%f", &valores[i]);
		}



		p=(maior(valores, nlinhas) - menor(valores, nlinhas))/10;

		b1=menor(valores, nlinhas) + p;
		b2=b1 + p;
