Logic & Control Flow Bugs

Errors in conditional statements, loops, and program logic that cause unexpected behavior

[6 examples] Array index out of bounds Program accesses invalid array indexes, causing crashes or errors. memoryundefined behavioredge case	6 examples
[8 examples] Buffer overflow Data exceeds allocated memory, risking crashes or security issues. memorysecurityc++	8 examples
[1 examples] Divide by zero Attempted division using zero, causing runtime errors or crashes. logicedge caseundefined behavior	1 examples
[1 examples] Uninitialized variable Variable used without an assigned value, causing unpredictable behavior. undefined behaviorlogicc++	1 examples
[2 examples] Variable shadowing Inner variable hides an outer one, leading to confusion or bugs. code qualitylogicdebugging	2 examples
