Simple int -> char conversion failing...
Hi,
I'm trying to convert an int to a char, just to see if the value entered is a alphabetic character. Here's what I have in my method:
Code:
void FillUserArray( int userArray[], int arraySize )
{
int i = 0; //array indexer
int j = 1; //counter for output format
int x; //holders for user input
while( i < arraySize )
{
printf( "#%d: ", j );
scanf( "%d", &x );
userArray(i) = x; //code pasting into forum doesn't allow [ ]
if( isalpha( (char)x ) )
printf( "no alpha" );
if( x < 1 || x > 47 )
{
printf( "\nThe number you are entering cannot be less than one, and no greater than forty-seven.\n\n" );
}
else if( HasBeenAssigned( userArray, arraySize, x, i ) == x )
{
printf( "\nPlease make sure the number you are entering has not already been assigned.\n\n" );
}
else
{
i++;
j++;
}
}
}
When scanf reads a letter into x, though, it just loops endlessly. How can I detect if the value entered is a character, and then print something if it is?
