Hi,

I want to count the number of characters of a string. Try to do it as follows.

C++ Syntax (Toggle Plain Text) 
  1. 	int iSpace = 0;
  2. 	int iLength;
  3.  
  4. 	string strTemp("This is a line                      of text");
  5. 	iLength = strTemp.length();
  6.  
  7. 	cout << iLength << endl;
  8.  
  9. 	for(int i = 0; i < iLength; i++)
  10. 	{
  11. 		if((strTemp.at(i) == ' ') || (strTemp.at(i) == '\t') || (strTemp.at(i) == '\0'))
  12. 		{
  13. 			iSpace ++;
  14. 		}
  15. 	}
  16. 	printf("\nNumber of characters %d", (iLength - iSpace));

Can you guys comments on my code, either this way is ok or bad attempt

yup...looks fine to me. How about modifies it for user inputs? See if it can manipulate with users' requirements

Dealing with the user inputs wont difficult. Anyway I'll check it. What I'm really worried about is the way I find the characters of the string.

Easy...Try to insert the characters into an array. That way, you can see what contains in it more clearly

Use isspace for a check like this.
cpp Syntax (Toggle Plain Text) 
  1. for(int i = 0; i < iLength; i++)
  2. {
  3.          if(!isspace(strTemp.at(i)))
  4.          {
  5.                   iSpace++;
  6.          }
  7. }

Correction to WolfPack post....

C++ Syntax (Toggle Plain Text) 
  1. for(int i = 0; i < iLength; i++){
  2.             if(isspace(strTemp.at(i)))
  3.             {
  4.                               iSpace ++;
  5.             }
  6.     }

if you meant by ignoring the white spaces, you can use a struct @ while(ws != '\t')
