char aChar = digits[i];

Safer Method:

char aChar = '0' + i;

Generic Method:

itoa(i, ...);

sprintf(myString, "%d", i);

C Method:

std::ostringstream oss;
oss << i;

In addition to these basic methods, you can also use various creative approaches, such as:

Joe's Way:

char aChar = '6'; //int i = 6;

Boss Way:

char aChar = '6';

Nasa's Way:

//Waiting for reply from satellite...

For more complex scenarios involving random number generation and file access, you can utilize additional functions:

srand((unsigned) time(NULL));
int i = rand() % 10;
char aChar = '0' + i;
std::string fileName = aChar + ".txt";
std::ifstream inFile(fileName);

No matter which method you choose, converting an int to an ASCII character is a straightforward task that can be accomplished using a variety of techniques.
