Templates are the generic data type. It converts into any type of data type automatically. We do not have to write float, int, char, string etc.
Note: For both the header files iostream and conio you can write constream(common for both).
#include<constream.h> template void fun(t n) { cout << n << endl; } void main() { clrscr(); fun(10); //integer fun(10.48); //float fun('A'); //character fun("tanmay"); //string getch(); } Output: 10 10.48 A tanmay
