String

[JTan]

May I know how to pass in a string parameter and to declare a string return-type?

 

[icici]

try out this

#include <......> // header files as
#include <......> // required by
#include <......> // application

void main(void)
{char mystring[21];
int ret_value=0;
memset(mystring, 0, sizeof(mystring));

ret_value=Get_Input(mystring, column, row, length, .....other para)

{...
...
code to check return value
}
}


int Get_Input(char *txt,int col, int row,int length,int type)



the function Get_Input would have to be written explicitly by u to accept the character values and check the length. U can also set the row, column, foreground and background colors and any other validations if required.

use the return type as char*

char* function()
{
return &quot;hello&quot;;

thanks a lot!

you may use char * as the data type for passing in returning a string, example:

char* func (char * a)
{
char b[5] = &quot;halo&quot;;

//codes are here

return b;
}

Trying and exploring is adventuring

I disagree with Andrew and Ion. You should never return a local (automatic) char* variable because the pointer is defined only for the function scope. At least, set the pointer returned by the function to static memory:


char * foo(void)
{
static char a[6] = &quot;hello&quot;;
return a;
}



Ion and Andrews code, for example, does not work on my machine.
