char c[15];
//Funzione per codificare una stringa
char encode(char *c){
int i,n;
char f[((strlen(c))*2)+1];
char a;
for(i=0; i<strlen(c); i++){
n=c[i];
n=126-(n-33);
a=n;
c[i]=a;
f[i*2]=c[i];
printf("%d\n",c[i]);
}
for(i=0; i<strlen(f); i++){
}
}

What do you mean by "doesn't work"?
Do you compile with C++ or with latest version of C? Only the latter supports (officially) VLA (variable length arrays) that the line 5 requires.
Also how do we know that c is actually a string and not just an array of char?
By the way the current C standard makes the "feature" on line 5 optional. The only standard that mandates this "feature" is C99.
