C > Chr() in C++??
For Chr() you can cast in C/C++.
For example:
will output:
For Asc()
C/C++ treat strings as a character array. Just index the string at 0, and cast it as an integer.
For example:
| Code: |
|
char x = 61; // ascii for "=" cout<<"x is: "<<x<<endl; cout<<"x is: "<<(int)x<<endl; |
will output:
| Code: |
|
= 61 |
For Asc()
C/C++ treat strings as a character array. Just index the string at 0, and cast it as an integer.

I don't know C++.
In C there is no concept of character as such; C only knows (integer) values.
Maybe you have something input from the user and you want to transform it into uppercase
| Code: |
| /* assume ASCII, will not work otherwise */
char * p = name; /* 'name' is the user input */ while (*p) { if ((*p >= 97) && (*p <= 122)) { *p -= 32; } ++p; } printf("uppercased is '%s'\n", name) |
Hi,
You need casting in C/C++
for example
I hope it'll help you.
You need casting in C/C++
for example
| Code: |
|
int i = 65; cout<<char(i); // It'll print character representing Ascii value of 65 i.e 'A' char a = 'A'; cout<<int(a); // It'll print ASCII value repreented by A, i.e 65 for(i = 65; i <= 90; ++i) cout<<char(i); |
I hope it'll help you.
oh.. thanks guys.
