Getting ASCII value

What function and header file does one use to get the ascii value of a character in a string?
For example
char st1[16] = "Hello, world.";
int t = 'ascii value of' st1[4];

Include iostream.h. You could also use printf(); if you prefer that.

To get the ASCII-value (in this case 111):

int t=st1[4];
cout << t;

To get the character (in this case the 'o'):

int t=st1[4];
cout << (char)t;

That works great, thank you.

Now I was wondering how to put the ASCII value back into a string as a character.

Such as~

int a = 65;
char st[16];
st[16] = 'character representation of' (a);

Oh, well, why not?

Code:

---


char Str[8]; //Create a string (array)
Str[0]='A'; //Set element 0 to A
Str[1]=45; //Set element 1 to ASCII-value 45

There is a simpler function that does this.
Ex:
#include <conio.h>
...............................
int ascii;
char ch;
ascii=getch();
This should do it.:)
