    Question C programming HELP

    Someone please help. I need help converting the following 2 algorithms into C.


    Dollar_Manipulator
    Set cash(index) to 10*
    Set num to 2
    Repeat
    Add 1.5 to cash(num)
    Add 2 to num
    Until(num == 10)
    Set num to 1
    Repeat
    If (num%3 == 0) Then
    Subtract 3.3 from cash(num)
    EndIf
    If (num%4 == 0) Then
    Multiply cash(num) by 2
    EndIf
    Until (num == 10)
    Prompt for num
    Get num
    Set lucky_num to (num%10)
    Set num to 1
    Repeat
    If (num == lucky_num) Then
    Do Nothing
    Else
    Add cash(num) to cash(lucky_num)
    EndIf
    Until (num == 10)
    Display cash(index)*
    End

    *Note that index = 10. You are declaring, initializing, and displaying the array of 10 locations numbered 1 to 10. Make necessary changes in C to reflect this.

    Misc_Program
    Set MAX to 10
    Set MID to 5
    Set MIN to 1
    Do index = MIN to MAX
    Set array(index) to 0
    Display array(index)
    If (array(index) == 2 Or 4 Or 6 Or 8) Then
    Add index— to array(index)
    Else
    Add index to array(index)
    EndIf
    EndDo
    Display modified array message
    Do index = MIN to MAX
    Display array(index)
    EndDo
    End

    what exactly do these algorithms do?

    for setting the flags here is what you do
    Code:
    int flag;
    //for the flag is set
    flag = 1;
    //for unsetting the flag
    flag = 0;
    //for conditions if flag is on
    if(flag)
    {
    	//...
    }
    else
    {
    	//...
    }
    //etc.
    what I mean by flags is the "action" or variable you used SET on.
    Asking the right question is sometimes more important than knowing the answer.

    This reeks of homework, so I'll offer tips instead of code. In the case of the Repeat..Until statements, consider using a while loop. cash(index) is an array, so you can simply change the notation slightly to cash[index] to convert it to C. You might want to make use of the arithmetic assignment operators that C provides, such as +=, -=, and *=. Perhaps a for loop would be appropriate for the Do construct. Everything else is simple enough for you to figure out with a little effort.

    My best code is written with the delete key.

    aha

    prelude---can you elaborate more
    " programming is 1% syntax and 99% logic "
