Veran tengo mi siguiente código pero no se que tan correcto este o si lo que hago esta permitido y número 2 también no sé si usar apuntadores seria mejor en este caso :S podrian ayudarme a revisar mi código y decirme mis errores al compilar me sale

ld: in tienda_mod, can't link with a main executable
collect2: ld returned 1 exit status

solo dos errores, programo bajo ANSI C en Linux su ayuda me podria ayudar :D

#include <stdio.h>
#include<string.h>
struct articulos {
char art[5][50];
float pre[5],tot[T];
int can[5];
char menu () {
char op;
struct articulos comp;
strcpy(comp.art[0],"papel");
strcpy(comp.art[1],"colores");
strcpy(comp.art[2],"libreta");
strcpy(comp.art[3],"carpeta");
strcpy(comp.art[4],"plumas");
comp.pre[0]=.50;
comp.pre[1]=5.43;
comp.pre[2]=20;
comp.pre[3]=10;
comp.pre[4]=4.5;
printf("\n\tARTICULOS\t\tPrecio");
printf("\n\t 1- %s\t\t%.2F",comp.art[0],comp.pre[0]);

total(con1,con2,con3,con4,con5);
return 0;
}
 
De entrada, lo que veo es que no has declarado las funciones... las estas "haciendo" pero no declarando....

otra que veo, es que en tu switch del main, estas evaluando la variable "op" cuando segun yo, deberias de evaluar a "p" que es el valor retornado de tu funcion "menu".

la ultima, es que tu struct esta medio raro... por que incluyes ahi un menu?


PD: Cual es el problema a resolver?
 
Bueno aqui esta lo que me marco el Codeblocks:
