Struct

[Maerle]

What's missing in this program? i'm with some details problems.
I think there's something wrong in the return of the function, but i don't know how to correct.

#include <cstdlib>
#include <iostream>
#include <conio.h>
using namespace std;
#define QUTY 12

int number_of_days (int);

struct months {
       int  num_mon;
       char name[10];
       char abrev[3];
       int  num_days;
};

struct months month[QUTY];

int main () {
    int i, mes;
    
    char *name[] = {"Janeiro", "Fevereiro", "Marco", "Abril", "Maio",
                   "Junho", "Julho", "Agosto", "Setembro", "Outubro",
                   "Novembro", "Dezembro"};
    char *abrev[] = {"Jan", "Fev", "Mar", "Abr", "Mai", "Jun", "Jul",
                    "Ago", "Set", "Out", "Nov", "Dez"};
                   
    for (i = 0; i < QUTY; i++) {
        strcpy (month[i].name, name[i]);
        strcpy (month[i].abrev, abrev[i]);
        if (i == 3 || i == 5 || i == 8 || i == 10)
             month[i].num_days = 30;
        else if (i == 1)
             month[i].num_days = 28;
        else
             month[i].num_days = 31;
        month[i].num_mon = i  + 1;
        
        cout << "Month: " << month[i].name << "(" << month[i].abrev << ")" << "     Number: ";
        cout << month[i].num_mon << "    Days: " << month[i].num_days << endl;
    }
    
    cout << "\nEnter the number of one month: ";
    cin >> mes;
    
    cout << "\n\nTotal days of the year until " << month[mes - 1].name << ": " << number_of_days(mes);
   
    getch();
}

int number_of_days (int a_month) {
    int index, days = 0;
    
    for (index = 0; index < a_month - 1; index++)
        days += month[index].num_days;
   
   return days; 
}

Details of the question:
Write an struct to describe a month of one year.
The struct should be able to store the name of the month, the three-letter abbreviation month, the number of days and the number of the month.
Define a matrix of 12 structs and initialize it with data from a not leap year.
Write a function that takes the number of months and returns the total days of the year until that month. Assume that the struct and the matrix were declared as external.

i noticed that you are not using string but you are inserting strings in a char array at each position at row 21 and 24 why?
also dont forget to include string if you are working with them.

Indeed, be sure to #include <cstring>

Aside from that, the program appears to work fine... what's the issue, may I ask?

I can't believe the problem was only this.
It's working fine now.
Thank you.

what's the issue, may I ask?

The question is under the program.

Do you know a better way to do it?

 char *name[] = {"Janeiro", "Fevereiro", "Marco", "Abril", "Maio",
                   "Junho", "Julho", "Agosto", "Setembro", "Outubro",
                   "Novembro", "Dezembro"};
    char *abrev[] = {"Jan", "Fev", "Mar", "Abr", "Mai", "Jun", "Jul",
                    "Ago", "Set", "Out", "Nov", "Dez"};

" A" this means it's a string, 'A ' means it's a char. Right now you are inserting strings in a char* array you might want to try
also string is an array of chars a char is a single letter

#include <string>

 string name[] = {"Janeiro", "Fevereiro", "Marco", "Abril", "Maio",
                   "Junho", "Julho", "Agosto", "Setembro", "Outubro",
                   "Novembro", "Dezembro"};
    string abrev[] = {"Jan", "Fev", "Mar", "Abr", "Mai", "Jun", "Jul",
                    "Ago", "Set", "Out", "Nov", "Dez"};
