WhiteSpaces and Blank Lines

[GarnetHuynh]

Hi,

Need help for a ‘C’ Code to ignore WhiteSpaces (Carriage Return, Enter, etc) and Blank Lines while reading an input file.

Thanks,
Marconi.

I’m not sure what compiler your using but the include file ctype.h has a macro called isspace() that can be called on characters , like:

<br /> char ch = cin.get()<br /> if ( isspace ( ch ) )<br /> {<br /> cout &lt;&lt; &quot;read a space&quot; ;<br /> }<br />

1 2 3 4 5 6 7

<br /> char ch = cin.get()<br /> if ( isspace ( ch ) )<br /> {<br /> cout &lt;&lt; &quot;read a space&quot; ;<br /> }<br />

The definition is listed as

The isspace() function returns non-zero if its argument is some sort of space (i.e. single space, tab, vertical tab, form feed, carriage return, or newline). Otherwise, zero is returned.
