hi ppl,
im having a problem with this program.
The thing is that i need to enter the license, age and level of education of an amount of ppl, but dont know how many.
then i have to get the percentaje of runners and sellers, the average age, amount of ppl acording to education level, and who have the highest level of education (runners or sellers).
the code is below with some comments explaining it.
if dont understand something, just ask!

// licencias.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>

#define total_gente 20

using namespace std;


struct datos_persona     // stuff for one person
{ 
	char licencia;    // license
	int edad;         //age
	char educacion;   // education
}

void edades (int edades);  // this is for gettin the media for ages
void comparar_educacion (int &uni, int &tecnico, int &seccompleto, int &secincompleto, int corredor4, int corredor3, int corredor2, int corredor1, int vendedor4, int vendedor3, int vendedor2, int vendedor1); // this is to get the max average of education
void mostrar_totales_educacion (int &uni, int &tecnico, int &seccompleto,  int &secincompleto); // this is for showin all the data about education
 

int main(int argc, char* argv[])
{
	int gente, uni, tecnico, seccompleto,  secincompleto;


// gente is a counter for all ppl im entering
// uni means if the person has a university degree
// tecnico is if the ppl did a highschool oriented to technology
// seccompleto is for those who completed the highschool
// secincompleto is for all ppl who didnt finish highschool

thanks!!
gispe!!

It seems you have never seen such basic C++ construct as an array.
Please, take your text-book on programming then search and study "An array" part.
After that you will never write functions with v1, v2, v3, v4 and so on parameters.
Moreover, you will never invent the only global struct and horrible ifs cascade to solve so simple problem...

my question is how can i do to make the part to compare the max if dont know how many i have of any of them..

You store a copy of the very first value read in to your max_value variable.
As you read in every other data item, compare it to max_value. If the new value is greater, store that to max_value.

This works if you have just one input, or a billion. You don't need to know how many there will be.

yes, i know, but they asked to use a struct :S

Exactly! Think about an array (or vector) of structures.
