Why is it that i can not use the clrscr() in SoloLearn code playground?

Question

Clear screen

Answer 1

How do you think your code is executed? On your device? On their servers? Which screen do you want to clear if your results are displayed in an Android display widget or the web browser (or accordingly depending on the device you use)?

Also, C does not come with builtin support for attached display devices. There is thus no clrscr function in C.

Answer 2

I saw this program in another Apps.. I noticed some functions were not discussed in SoloLearn

Answer 3

conio.h was part of the Borland Turbo C suite that contained functions to control an integrated console. Turbo C is out of commission for several decades now and should not be used.

Way back 1998 i learned about this turbo c but not all were taught. It's just now i go back learning programming.. Thanks for info.

Answer 5

#include < stdio.h >
#include < conio.h >
void main ( ) {
int n , r , sum = 0 , temp ;
clrscr ( ) ;
printf ( " enter the number = " ) ;
scanf ( " % d " , & n ) ;
temp = n ;
while ( n > 0 ) {
r = n % 10 ;
sum = ( sum * 10 ) + r ;
n = n / 10 ;
}
if ( temp == sum )
printf ( " palindrome number " ) ;
else
printf ( " not palindrome " ) ;
