>how can i identify that "are" existed in the *inputx ??
Code:
#include <string.h>

if ( strstr ( inputx, "are" ) != NULL ) {
  /* "are" was found */
}
else {
  /* Not present */
}
>main()
int main ( void )

>char xyz[20] = "hellohowareyoudoingthere";
This totally writes past the end of the array. Do this instead if you have trouble counting characters in a string literal:
Code:
char xyz[] = "hellohowareyoudoingthere";
>processinfo(xyz);
>}
Squeeze a "return 0;" in between those two lines.
