How to Convert an Integer to an ASCII Character in C/C  ?

Converting an Integer to an ASCII Character

In C/C , converting an integer to an ASCII character can be achieved using several methods:

Straightforward Approach:

char digits[] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9' };
char aChar = digits[i];
Copy after login

Safer Approach:

char aChar = '0' + i;
Copy after login

Generic Approach:

itoa(i, ...);
Copy after login

Handy Approach:

sprintf(myString, "%d", i);
Copy after login

C Approach:

std::ostringstream oss;
oss << 6;
Copy after login

Other Notable Approaches:

  • Boss Way: Creating a custom converter function.
  • Studboss Way: Directly assigning the character representation to a char variable.
  • Peter Pan's Way: Using a switch-case block to handle individual digits.
  • Gravity's Way: Expressing incredulity at the simplicity of the task.

Regarding Random Number Generation:

To generate a random number and convert it to a char, you can use rand() to generate the number and then follow the conversion methods described above. To access a file with the extension .txt, you can use ifstream in conjunction with the converted character.
