Code:

#include <stdio.h>
#include <stdlib.h>
10+rand()%90
int main()
{
input-input%10)/10

if(input==random number)
{
      printf("You have won $10000\n"); 
      break;
}
else
{
     if (input%10==random number || ((input-input%10)/10)==random number)

    printf("\n hint=%d",number);
    int input=0;
    printf("\nguess a number:");
    scanf("%d",&input);getchar();

if(input==number){
