Morra - Odds and Even - c

Question

Im writing a code that evolves the computer and I entering numbers and added them together to see who wins.
There are three problems:
Problem 1: When I try to recall the 'main()' function the 'game()' wont appear.
Problem 2: I can't seem to run the code forever until user decides to stop.
Problem 3: The point system isn't accurate enough.
Any help would be grateful.
Here's the code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int human_fingers;
int comp_fingers;
int menu_choice;
int answer;
int count = 1;
int point1 = 0, point2 = 0;
int total;
void intro() {
printf("Welcome to Morra - Odds and Even!\n\n");
printf("The rules of the game are pretty simple\n");
printf("You and the computer will pick a side each round\n");
printf("You must enter a number and the total sum will determine the winner!\n\n");
}
void example() {
printf("You picked even, by default the computer will be odd this round\n");
printf("You entered 3 and the computer entered 5\n");
printf("3 + 5 = 8, so you win because you choose even!\n");
}
void game() {
while(count < 7)
{
count = count + 1;
printf("Enter a number to choose a side:\n");
printf("Even [1] / Odd [2]\n");
scanf("%d", &menu_choice);
while((menu_choice<1) || (menu_choice>2)){
printf("Invalid entry, please Enter 1-2: ");
scanf("%d",&menu_choice);}
if(menu_choice == 1)
{
printf("The computer will be odd this turn\n");
printf("\nPlease enter an number (1-10)\n");
scanf("%d", &human_fingers);
while((human_fingers<1) || (human_fingers>10)){
printf("Invalid entry, please enter 1-10:");
scanf("%d",&human_fingers);}
printf("Computer is choosing a number....\n");
srand(time(NULL));
comp_fingers = rand() % 10 + 1;
printf("You: %d\n", human_fingers);
printf("Computer: %d\n", comp_fingers);
int result;
result = human_fingers + comp_fingers;
printf("Total is %d\n", result);
total = result % 2;
if(total == 0)
{
printf("This turn goes to You!\n\n");
printf("You: %d\n", point1 + 1);
printf("Computer: %d\n\n", point2 + 0 );
point1++;
}
else
{
printf("This turn goes to Computer!\n\n");
printf("You: %d\n", point1 + 0 );
printf("Computer: %d\n\n", point2 + 1);
point2++;
}
}
if(menu_choice == 2)
{
printf("The computer will be even this turn\n");
printf("\nPlease enter an number (1-10)\n");
scanf("%d", &human_fingers);
while((human_fingers<1) || (human_fingers>10)){
printf("Invalid entry, please enter 1-10:");
scanf("%d",&human_fingers);}
printf("Computer is choosing a number...\n");
srand(time(NULL));
comp_fingers = rand() % 10 + 1;
printf("You: %d\n", human_fingers);
printf("Computer: %d\n", comp_fingers);
int result;
result = human_fingers + comp_fingers;
printf("Total is %d\n", result);
total = result % 1;
if(total == 0)
{
printf("This turn goes to Computer!\n\n");
printf("You: %d\n", point1 + 0);
printf("Computer: %d\n\n", point2 + 1);
point1++;
}
else
{
printf("This turn goes to You!\n\n");
printf("You: %d\n", point1 + 1);
printf("Computer: %d\n\n", point2 + 0 );
point2++;
}
}
}
if(point1 > point2)
printf("You won, you beat the computer!\n");
else
printf("Unlucky the computer won!\n");
}
void end(){
printf("Game has ended!\n");
}
int main()
{
intro();
printf("Would you like an example to demostrate?\n");
printf("Yes [1] / No [2]\n");
scanf("%d", &answer);
if( answer == 1 )
{ example();
printf("\n\n");
game();
}
else
{ printf("\n\n");
game();
}
end();
printf("Would you like play another game?\n");
printf("Yes [1] / No [2]\n");
scanf("%d", &answer);
if( answer == 1)
{
main();
}
else {
printf("Thanks for playing MORRA - ODDS AND EVEN.");
}
return 0;
}

Answer 1

Why not:
int main()
{
for(;;) // Infinite loop. -- equivalent of while(1) if you prefer.
{
intro();
printf("Would you like an example to demostrate?\n");
printf("Yes [1] / No [2]\n");
scanf("%d", &answer);
if( answer == 1 )
{ example();
printf("\n\n");
game();
}
else
{ printf("\n\n");
game();
}
end();
printf("Would you like play another game?\n");
printf("Yes [1] / No [2]\n");
scanf("%d", &answer);
if( answer != 1)
{
printf("Thanks for playing MORRA - ODDS AND EVEN.");
break;
//^___ exit the infinite loop.
}
}
return 0;
}
Recalling the main you should definitely not, in almost any case. Just create loops if you want to repeat everything.
