Warning C6296

Ill-defined for-loop. Loop body only executed once.

Remarks

This warning indicates that a for-loop might unintentionally execute only once. A loop with an unsigned index counting down from zero or a mistaken use of == might cause this warning.

Code analysis name: LOOP_ONLY_EXECUTED_ONCE

Example

The following example generates C6296. Each for-loop shown executes exactly once.

int main()
{
    for (unsigned int i = 0; i < 10; i--) {}   // C6296
    // Use the following line to resolve the warning:
    // for (unsigned int i = 0; i < 10; i++) {}

    for (int i = 0; i == 0; i++) {}   // C6296

    for (int i = 0; i < 1; i++) {}   // OK

    for (int i = 1; i > 0; i--) {}   // OK
}
