Thread: Single put routine to avoid overlapping words during iteration

I am trying to have a simple loop for random words that may be placed horizontally and/or vertically and/or diagonally depending on the allowed space and wordLength. Below, is what I came up with but there is significant overlapping and broken words. Is there a way to have the loop in a single 'put' routine for all direction?
All my attempts have resulted in buggier outcomes. Thanks

Code:

 //Check horizontal orientation and place the word if available spaces allow it
void putHorizzontalWord(char word[10])
{
    int rRow, rCol , ok , i;

    do
    {
        rRow = rand() % 10;
        rCol = rand() % 10;

        ok = 1;
        if(rCol + strlen(word) < 10)
        {
            for(i = 0;i < strlen(word);i++)
            {
                if(puzzle[rRow][rCol + i] == '*' ||
                    puzzle[rRow][rCol + i] == word[i])
                {
                    puzzle[rRow][rCol + i] = word[i];
                }
                else
                {
                    ok = 0;
                }
            }
        }
        else
        {
            ok = 0;
        }
    }
    while(ok == 0);
}

//Check vertical orientation and place the word if available spaces allow it
void putVerticalWord(char word[10]) //this, doesn't seem to work'
{
    int rRow, rCol , ok , i;

    do
    {
        rRow = rand() % 10;
        rCol = rand() % 10;

        ok = 0;
        if(rRow + strlen(word) < 10)
        {
            for(i = 0;i < strlen(word);i++)
            {
                if(puzzle[rRow + i][rCol] == '*' ||
                    puzzle[rRow + i][rCol] == word[i])
                {
                    puzzle[rRow + i][rCol] = word[i];
                }
                else
                {
                    ok = 1;
                }
            }
        }
        else
        {
            ok = 1;
        }
    }
    while(ok == 1);
}

//Check diagonal orientation and place the word if available spaces allow it
void putDiagonalWord(char word[10]) //this, doesn't seem to work'
