Pull Request Overview

This PR introduces example code into daliadmin.cpp that dynamically allocates an unsigned integer, performs two summation loops, and prints results.

  • Adds dynamic allocation and initialization of myvariablename
  • Implements two summation loops (linear and nested) and prints results
  • Does not clean up allocated memory
Comments suppressed due to low confidence (1)

dali/daliadmin/daliadmin.cpp:151

  • [nitpick] The variable name myvariablename is ambiguous and doesn’t follow camelCase conventions. Consider a clearer name like maxIterations or limit.
    unsigned *myvariablename = new unsigned;

This dynamically allocated unsigned is never freed, causing a memory leak. Consider using a stack variable or managing its lifetime to ensure delete is called.

Suggested change
unsigned *myvariablename = new unsigned;
*myvariablename = 10000;
printf("%d\n", *myvariablename);
unsigned __int64 sum = 0;
// sum up all the numbers from 0 to 9999
for (unsigned x=0; x<*myvariablename; x++)
{
sum += x;
}
printf("%llu\n", sum);
sum = 0;
// sum up all the numbers from 0 to 9999 N times
for (unsigned x=0; x<*myvariablename; x++)
{
for (unsigned y=0; y<*myvariablename; y++)
unsigned myvariablename;
myvariablename = 10000;

[nitpick] Instead of dynamically allocating a single unsigned, declare it as a local variable (e.g., unsigned myVariableName = 10000;).

Suggested change
unsigned *myvariablename = new unsigned;
*myvariablename = 10000;
printf("%d\n", *myvariablename);
unsigned __int64 sum = 0;
// sum up all the numbers from 0 to 9999
for (unsigned x=0; x<*myvariablename; x++)
{
sum += x;
}
printf("%llu\n", sum);
sum = 0;
// sum up all the numbers from 0 to 9999 N times
for (unsigned x=0; x<*myvariablename; x++)
{
for (unsigned y=0; y<*myvariablename; y++)
unsigned myvariablename = 10000;
printf("%d\n", myvariablename);
unsigned __int64 sum = 0;
// sum up all the numbers from 0 to 9999

The format specifier %d is for signed integers; for an unsigned value use %u to ensure correct output and defined behavior.

Suggested change
printf("%d\n", *myvariablename);
printf("%u\n", *myvariablename);

Using %llu assumes unsigned long long; for portability with unsigned __int64, consider using the PRIu64 macro or matching the exact type’s specifier.

This nested loop results in O(n²) complexity and may impact performance for large values. Consider whether the double summation is necessary or can be optimized.

Suggested change
for (unsigned x=0; x<*myvariablename; x++)
{
for (unsigned y=0; y<*myvariablename; y++)
{
// nested loop
sum += x;
}
}
printf("%llu\n", sum);
// Calculate the sum directly using a mathematical formula
sum = *myvariablename * ((*myvariablename - 1) * *myvariablename / 2);
// The formula computes the sum of x repeated *myvariablename times for all x from 0 to *myvariablename - 1
printf("%llu\n", sum);
printf("%llu\n", sum);
