For, break, and continue

Why use this example

Use this pattern to isolate Solidity branching, looping, assignment, and function-call syntax before combining it with contract state. The entry isolates for, break, and continue so its input, result, and state changes stay easy to compare.

Solidity to run

function sumOddBelowSeven() public pure returns (uint256 total) {
  for (uint256 i = 0; i < 10; i++) {
    if (i == 7) break;
    if (i % 2 == 0) continue;
    total += i;
  }
}

sumOddBelowSeven()

Official Solidity reference

Compare this focused investigation with the complete language definition in the Solidity documentation.

What to expect

The loop skips even values, stops at seven, and returns the sum of 1, 3, and 5 as 9.

Continue the investigation

Change a value, add another expression, or open Inspect after the run. Accepted entries remain available to the next entry, and the clean replay keeps the complete result reproducible.
