can we use any function to display our input

without using a " printf " function? does c support such this
possibilities?

Yes. Use the standard fprintf(), vprintf(), vfprintf(), puts(),
fputs(), putchar(), putc(), fputc(), or write your own.

Standard C includes puts, fprintf, fputs, putchar and fputc which can
be used to print text into stdout or other specifi file streams.

could you show me an example using
your own function?

As such custom functions are usually very platform specific, it would
not be topical for this group. However, if you _really_ want to see
such code, try asking Mr. Navia nicely. He's in a very OT mood right
now.

Yes, as many people know this topic is covered in detail in The C
Programming Language (2nd Edition) by Brian W. Kernighan, and Dennis
Ritchie, there is an example in the book and they explain how this
accomplished using a function.

void minprintf (char *fmt, ... )
{
va_list ap;
char *p, *sval;
int ival;
double dval;
va_start (ap, fmt);
for(p=fmt; *p;p++)
{
if (*p != '%')
{
putchar (*p);
continue;
}
switch (*++p)
{
case 'd': ival = va_arg(ap,int);
printf("%d",ival);
break;
case 'f': dval = va_arg (ap, double);
printf("%f",dval);
break;
case 's': for (sval = va_arg(ap,char *);*sval;sval++)
putchar (*sval);
break;
default: putchar(*p);
break;
}
}
va_end(ap);
}

void main()
{
.....
}

so this a code and what shall we write in the Main program?
