How to convert a code ASCII to decimal!?

Question

in c++ ..
If I have an int x='10'
how to calculate​ the result !
as we know number 0 to 9 ASCII equal 48 to 57 decimal ... and after what !?

Answer 1

Yet another mind blowing request. You cannot calculate it lol. Refer to an ASCII table, or you can always do:

for (int num = 0; num < 100; num++) {
cout << static_cast<char>(num);
}

to take a look. If you have an int x = 10, do:

cout << static_cast<char>(x);

Answer 2

shannon formula. thats one if you know how to use it

Answer 3

I didn't get correctly what you are asking for it seems like you are asking for string to integer conversion. for string to integer conversion you can use standard library
include <stdlib.h>;
then use atoi function like this
int number = atoi("56");

Answer 4

I mean how can I calculate it without machine .. etc !
and thx for ur answer 😊
