Question

i need help with this program, I am stuck at it

/* My typedef structures from a different file */

Typedef struct {

                             Char name[21];

                             Double attempts[N_ATTEMPTS];

                             Double personal_best;

                             Double deviation;

                             }jumper_t;

Typedef struct {

                             Double average_of_best;

                             Double winning_jump;

                             }stats_t;

Pseudocode

/*-------------------------------------------------------------*/

main   

out_file = open_out_file ();                     

get_data(IN_FILENAME, jump_list);                

get_stats(jump_list, &jump_stats);             

print_all(out_file, jump_list, &jump_stats);

    stats_t *jump_stats )                                  /* in & out */         

                      {   

Zero out the average_of_best. (HINT: use the -> notation)    

Zero out the winning_jump.      

Loop from r=zero to r< NCOMPETITORS increment by one   

{        

set the jumper's personal_best to the jumper's first jump        

loop from c=one to c< N_ATTEMPTS increment by one         

{             

figure the jumper’s personal_best jump(use an IF)      

   }         

add the jumper's personal _best jump into the running total average_of_best         

loop from c=zero to c< N_ATTEMPTS increment by one         

{             

figure the winning_jump (use an IF)        

}    

}         /* end of the loop, r< NCOMPETITORS */    

compute the average of the best jumps

    loop from r=zero to < NCOMPETITORS increment by one   

{          

figure the jumper's deviation from the winning_jump             

(deviation is: winning_jump - jumper's personal_best jump)   

}  

return
