[Solved] how to create input like answer

by


some fundamental coding errors needs to be addressed here along with logical flaw.

before we proceed lets format to 4 spaces

int main()
{
    /* Lets simplify these two statements */
    // char ce[] = {"ceil"};
    // char fl[] = {"floor"};

    char *ce = "ceil";
    char *fl = "floor";

    /* format this into one line .. */
    printf("hello choose one ceil or floor : \n" );
    /* instead of accepting two values, you may want to accept one 
       as per the question asked above the input is either floor or ceil */

    /* lets declare a buffer to store the choice */
    char choice[255];

    /* scan choice */   
    scanf("%s", choice );

    /* Below wont work, ceil and floor are already char * 
       &ceil and &floor will make them char ** so this wont work */ 
    // scanf("%s", &ceil);
    // scanf("%s", &floor);


    /* some commentary on this code snippet below */

    /* 1. ce is an address, a positive integer hence the if statement 
          will always evaluates to true
       2. else has an expression else() that is wrong syntax .
       3. else ending with ; another wrong syntax.

       lets say the below snippet wont compile 

    if ( ce ) 

        testdovom();

    else ( fl );


        testaval();

    */

    /* instead we use strcmp function from string.h 
       and  check if choice is "floor" or "ceil" */

   if( strcmp(choice, ce) == 0 )
   {
        testdovom();
   }
   else if( strcmp(choice, fl) == 0 )
   {
         testaval();
   }
   else
   {
        /* we've got something we donot handle */
        printf("Invalid input");
   }


    return 0;
}
