I have this problem and in the code that gives us example structures are handled but from what I understand a structure can not be compared, what I want to do is compare if register 1 is greater than 18 then increase a counter and so on for the rest.

You can compare the values of the elements of the structures by accessing the notation estructura.elemento or in the case that the structure is referenced with a pointer with estructura->elemento .

As an example if the structure and arrangement or vector are as follows:

struct persona{
    int sexo;
    int edad;
    int estado;
};

struct persona lista[15];

You can scan the list as follows:

// variables para almacenar los resultados
int hombressolteros = 0;
int hombrescasados = 0;
int mujeressolteras = 0;
int mujerescasadas = 0;
int totalsolteros = 0;
int totalcasados = 0;
int menoresedad = 0;

for (int i = 0; i < 15; i++) {

    // Comprobar si es mayor de edad
    if (lista[i].edad < 18) {
        menoresedad++;
    }
    // Comprobar si es hombre
    else if (lista[i].sexo == 1) {

        // Determinar si esta casado
        if (lista[i].estado == 1) {
            hombrescasados++;
        }
        else {
            hombressolteros++;
        }
    }
    // si es mujer
    else {
        // Determinar si es casada
        if (lista[i].estado == 1) {
            mujerescasadas++;
        }
        else {
            mujeressolteras++;
        }
    }
}

// Totales
totalcasados = hombrescasados + mujerescasadas;
totalsolteros = hombressolteros + mujeressolteras;
