Explanation / Answer
#include <iostream>
#include <stdlib.h>
#include <time.h>
using namespace std;
struct game{
int save[3];// Random number generating
int input[3];// User input number
int st;// strike
int b;// ball
};
void fxn( struct game);
int main()
{
int i, j;// for loop
struct game ob;
srand((unsigned)time(NULL));
printf("Start ");
for (i = 0, j = 0; i < 3; i += (i == j))
{
ob.save[i] = rand() % 10;
for (j = 0; j < i && ob.save[i] != ob.save[j]; j++);
}
fxn(ob);
printf("End ");
}
void fxn( struct game ob)
{
int i, j;
while (1)
{
while (1)
{
printf(" Enter 3 numbers << ");
scanf("%d%d%d", &ob.input[0] , &ob.input[1] , &ob.input[2]);
if ((ob.input[0] < 0) || (ob.input[0] > 9) || (ob.input[1] < 0) || (ob.input[1] > 9) || (ob.input[2] < 0) || (ob.input[2] > 9))

}
else if ((ob.input[0] == ob.input[1]) || (ob.input[0] == ob.input[2]) || (ob.input[1] == ob.input[2]))
{

}
else break;
}
ob.st = 0;
ob.b = 0;
for (i = 0; i < 3; i++)
{
for (j = 0; j < 3; j++)
{

}
else
{
ob.b++;
}

}
}
}
printf("%d Strike %d Ball", ob.st, ob.b);
if (ob.st == 3) break;
}
}
