rock, paper, scissor help C programming

jmf777

Hi here is my problem I want to have the outcome of my rock paper scissors game to print outcomes like: You chose paper and I chose rock. You win. The value for player_choice and machine_choice is declared in select.cpp (listed below).

My question is how would I go about telling, the report.cpp code below to check the select.cpp code for the variable to print?

#include "p_r_s.h"

void report(outcome result, int *win_cnt_ptr,
int *lose_cnt_ptr, int *tie_cnt_ptr)

{

switch(result) {
case win:
++*win_cnt_ptr;
printf("%27s I chose");
printf("%c", player_choice);
printf("%27s you chose");
printf("%c", machine_choice);
printf("%27s You win.\n", "\"");
break;
case lose:
++*lose_cnt_ptr;
printf("%27s i chose");
printf("%c", player_choice);
printf("%27s you chose");
printf("%c", machine_choice);
printf("%27s You lose.\n", "");
break;
case tie:
++*tie_cnt_ptr;
printf("%27s A tie.\n", "");
break;
default:
printf("PROGRAMMER ERROR: Unexpected result!\n\n");
exit(1);
}
}

#include "p_r_s.h"

p_r_s selection_by_machine(void)
{
return ((p_r_s) (rand() % 3));
}
p_r_s selection_by_player(char x)
{
char c;

p_r_s player_choice;

printf("Input p, r, or s: ");
scanf("%c", &c);
switch (c) {
case 'p':
player_choice = paper;
break;
case 'r':
player_choice = rock;
break;
case 's':
player_choice = scissors;
break;
case 'g':
player_choice = game;
break;
case 'i':
player_choice = instructions;
break;
case 'q':
player_choice = quit;
break;
default:
player_choice = help;
break;
}
return player_choice;
}

yeah thats basically it. In select.cpp the player and the machine makes a choice of rock paper or scissor. In report.cpp I want to call the selection that the player and the machine made in select.cpp to report.cpp and print that selection.

I think you have to call the report() function in a loop and from the report function you have to call the function in select().


NOTE:Please use code tags while posting the code.

1.     printf("%27s I chose");

You do that all over the place; check your manuals because it is not correct.

kind regards,

You use a storage class specifier to tell the compiler the variable exists but it's not in this file:

Then just define the variables in another file:
The linker will hook the variable in one file to the code in the other file.

I've got the program to at least build and executed it by adding the underlined code.

to my header and my report function but now when I win. It prints funny characters like an up and down character before "you chose" and a smiley face box after "you chose." I'm now lost can someone please point me in the right direction. I'm assuming its because my outcome function is only returning a win or lose to main.
