What is the symbol for power?

What operator should we use to get a power of some no. Like I want to get 10^5. How can I get this in C++

C++ does not have an operator for that operation. Either you make yourself your own function, or use the preexisting pow() function: http://www.cplusplus.com/reference/cmath/pow/

cond() tests if a character is a digit, right? Why not use the built-in C++ function, saves you some work: http://www.cplusplus.com/reference/cctype/isdigit/ Same goes for num(), C++ has built-in functions for convertions from string/char to number: http://www.cplusplus.com/reference/cstdlib/ You should have a look in the different headers grouped in the STL, they can save you a lot of work in future projects: http://www.cplusplus.com/reference/ https://en.cppreference.com/w/cpp
