I was curious about how my compiler would handle these
attempts (QC 2.51), so I tried it, and it caught them
all! Next I tried:
 
scanf( "%d %d", i, j );
i/=j
 
Would you believe it caught this too ("Warning: user may
accidentally enter invalid input resulting in a runtime
divide exception")?
 
 
 
 
 
I didn't think so :-)
