#include<iostream>

using namespace std;
int main()
{
double cuota,dscto, importe=0;
char colegio, categoria;
int sw=0;
cout<<"Ingresar colegio de procedencia (N)acional,(P)articular:";

        break;

        switch (categoria)
        {
            case ´a´: dscto=.50*cuota;break;
            case ´b´: dscto=.40*cuota;break;
            case ´c´: dscto=.30*cuota;break;
            default: cout<<"Opcion no contemplada";
            sw=1;

        }
        break;
        case ´p´:
            switch(categoria)
            {case ´a´:dscto=.25*cuota;break;
         case ´b´:dscto=.20*cuota;break;
         case ´c´:dscto=.15*cuota;break;
         sw=1;
            }
        break;
        default: cout<<"Opcion no contemplada";
            sw=1;

    }
        if (sw==0)
        {
        importe=cuota-dscto;
        cout<<"El importe a pagar es:"<<importe;
    }
        cout<<endl;
}

When compiling I get it:

[Error] ctype: No such file or directory compilation terminated.

What am I doing wrong?

The libraries inherited from C are in two formats:

old name, the same as in C: stdio.h
new name, the extension disappears and a c is added to the start: cstdio

Now, the library ctype , in C is with this name: ctype.h , then to use it in C ++ we can use:

#include <ctype.h> // Nombre C
#include <cctype>  // Nombre C++

On the other hand, your program has several errors in the code:

siwtch should be switch

siwtch (colegio) // <<--- MAL
switch (colegio) // <<--- BIEN

Characters are indicated with the character ' instead of ´ . The cases, in addition, also go with two points:
```
case ´n´  // <<--- MAL
case 'n': // <<--- BIEN
```
It is not recommended to nest instructions switch . It is preferable to divide the code into functions

Keep an eye on the keys. There is break and instructions case outside of switch :

switch (colegio)
{
  case 'n':
    break;
}

switch (categoria)
{
    case 'a': dscto=.50*cuota;break;
    case 'b': dscto=.40*cuota;break;
    case 'c': dscto=.30*cuota;break;
    default: cout<<"Opcion no contemplada";
    sw=1;

}
break; // <<--- Por ejemplo este
