How to write a function that goes through an array of characters and eliminates any elements that ..

Answer / vivek

//This function returns true if valid character, else false
bool isCharacter(char unknownCharacter)
{

//Check whether the character falls between
// a ...z or A....Z
if( (unknownCharacter >= 'a' &&
unknownCharacter <= 'z') ||
unknownCharacter >= 'A' &&
unknownCharacter <= 'Z')
{

return true;

}
else
{

return false;

}


}

//This function removes non characters and returns array s
//effective size.
unsigned int removeNonCharacters(char *charArray, unsigned int arraySize)
{

//Lets decrement by non character as and when we identify
unsigned int effectiveArraySize = arraySize; .

//Algo: Traverse the array and in the mean time Identify
// non chars positions and move valid chars from right
// side of the array to fill those positions.

//used to traverse and mark valid chars.
unsigned int currentValidCharacterPosition = 0;

//Used to traverse and mark non valid character
unsigned int currentNonValidCharacterPosition = 0;


while( (currentValidCharacterPosition < arraySize) &&
(currentNonValidCharacterPosition < arraySize) )
{


if(isCharacter(charArray[currentValidCharacterPosition ])
{

//If we are here mean this is a valid character in
//the array, go to next character

currentValidCharacterPosition++;

}
else //This is a non character
{
//Mark the first non valid character position
currentNonValidCharacterPosition =
currentValidCharacterPosition ;

//move to findout valid character in the remaining
//array
while( (currentValidCharacterPosition <= arraySize) && (!isValidCharacter(characterArray[currentValidCharacterPosition]) )
{

--effectiveArraySize;

++currentValidCharacterPosition;
}//End While

//Check in the mean time whether we exhausted the
//array
if( currentValidCharacterPosition == arraySize)
{

return effectiveArraySize;

}//End If

//Move the valid character to fill the leftmost
//non valid character position.
characterArray[currentNonValidCharacterPosition]
= characterArray[currentValidCharacterPosition];

//Move on.
++currentValidCharacterPosition;

}//End Else (invalid character)


}//End While

return effectiveArraySize;
}
