Hi, I have a problem with the function

i=(abcdario[g]+h)%27;

, because i need to add this, but it gives me the error "invalid operands to binary +"

The full code is the following

#include<stdio.h>     //fopen() ,fclose() 
#include<stdlib.h>    //malloc()

int main (int argc, char*argv[])

     FILE *entrada, *salida;

     int caracter2(unsigned char x);

     char k,*b;
     typedef struct  
     {
         char min;
         char mayus;
     }alfabeto; 
     alfabeto abcdario[] = {{'a','A'},{'b','B'},{'c','C'},{'d','D'},{'e','E'},

The array is an array of structs, so you need something like i=(abcdario[g].min+h)%27;

Hi again, I made a new change in it, and the compilator dosn't give me problems, but when I try to open it by DOS, it ruterns a error, can someone help me with this plz

Since there are over 400 errors that can be returned, could you please be less vague and tell us what the error is, and where?

[Ancient Dragon]

What compiler are you using because mine gives a couple errors about using uninitialized variables which you need to fix before attempting to run that program.
