Passing a string into a function
PostPosted: Fri Feb 04, 2011 9:52 am     Reply with quote
I was to do something like this.

Code:
foo( "This is a string" );

void foo( const char *string ) {
int x;
for( x = 0; string[x] != '\0'; x++ )
  print_char( string[x] );
}


Now most of this code is just for clarification this is not what I am actually attempting to do. I want to pass a string without having to declare it first with something like. string = "This is a string"; and then call foo( string );

I want to be able to pass a string using only one line of code. Secondly, I want to be able to step through the string one character at a time.

I know I can do something like this
Code:
void foo( char string ) { // code }

Although the problem with that is it calls that function for each individual character and doesn't include the terminating character '\0'.

Any ideas?

Look at the thread immediately in front of this one 'Passing a const string'.
