What is an ideal variable naming convention for loop variables? [closed]

Answer 1

@JustMike . . . A FEW C EXAMPLES: . . . to accompany the Java ones.

NON-NESTED loop: . . . limiting scope where possible

/*LOOP_DESCRIPTION*/ {

    int i;

    for (i = 0; i < LOOP_LENGTH; i++) {

        // loop body
    }  
}

NESTED loop: . . . ditto

/*LOOP_DESCRIPTION*/ {

    int row, column;

    for (row = 0; row < ROWS; row++) {

        for (column = 0; column < COLUMNS; column++) {

            // loop body
        }
    }  
}

One good thing about this layout is it reads badly without comments, thereby encouraging them.
It's verbose perhaps, but personally this is how I do loops in C.

Also: I did use "index" and "idx" when I started, but this usually got changed to "i" by my peers.
