I am reading a piece of C heap sorting code and encounter this:
do{
printf("\n\t\t1:INSERT\n");
printf("\n\t\t2:SEARCH\n");
printf("\n\t\t3:DELETE\n");
printf("\n\t\t1:DISPLAY\n");
printf("Enter your choise\n");
scanf("%d",&choise);
switch(choise)
{
case 1: printf("Enter value to insert\n");
scanf("%d",&val);
last=insert(root,val);
break;
case 2:printf("Enter value for search \n");
scanf("%d",&val);
search(root,val);
break;
case 3:delete(root);
delete(last);
break;
case 4:printf("\n\tHEAP\n");
display(root);
break;
default : printf("INVALID choise ... can't you see properly?\n");
}
Anyone knows whats \t1
and \t2
in the printf
s and how do they work? I tried google but did not get any useful information.
Thank you.
\t
denotes a tab character. The 1
and 2
are nothing to do with it; they are just literal 1
and 2
.
