I'm quite happy with my code so far but I often make efficiency errors that I don't see when writing code. Have I missed anything?#include <stdio.h>#include <unistd.h>int main (){char end = 'N';int credit = 5, bet = 0, userInput = 0, cont = 0, victory;do{  while (cont == 0){    // Introduction of credit system to user    printf(\e[1;1H\e[2J);    printf(Your current credits are %d.\n, credit);    printf(How many credits would you like to bet?\n);    scanf(%d, &userInput);    printf(\e[1;1H\e[2J);    // Checking for valid credit input and adjusting credit/bet value according to input    if (userInput <= credit && userInput >= 1){      bet = userInput;      credit = credit - bet;      cont = 1;      printf(You have bet %d credits. Good luck!\n, bet);      sleep(2);      break;    }    if (userInput == 0){      printf(Invalid, bet must be a minimum of 1 credit.\n);      sleep(2);      cont = 0;    }    else{      printf(Invalid, input exceeded your credit value of %d.\n, credit);      sleep(2);      cont = 0;    }    // End of check  }  // Introduction countdown to execute after valid bet is placed  printf(\e[1;1H\e[2J);  printf(Ready?\n);  sleep(1);  printf(\e[1;1H\e[2J);  printf(3...\n);  sleep(1);  printf(\e[1;1H\e[2J);  printf(2...\n);  sleep(1);  printf(\e[1;1H\e[2J);  printf(1...\n);  sleep(1);  printf(\e[1;1H\e[2J);  printf(Spin!\n);  printf(\e[1;H\e[2J);  // Declaring var names for reel and loop  int firstReel, secondReel, thirdReel, loop = 0;  // Loop to print cycle reel 10 times  while(loop < 10){    sleep(1);    // Generating three random numbers    srand(time(NULL));    int rndOne = rand () %4;    int rndTwo = rand () %4;    int rndThree = rand () %4;    // Assigning random numbers to clearer var names    firstReel = rndOne;    secondReel = rndTwo;    thirdReel = rndThree;    // Switch statements for each reel    switch(firstReel){      case 0:        printf(Bell );        break;      case 1:        printf(Cherry );        break;      case 2:        printf(Orange );        break;      case 3:        printf(Horseshoe );        break;    }    switch(secondReel){      case 0:        printf(Bell );        break;      case 1:        printf(Cherry );        break;      case 2:        printf(Orange );        break;      case 3:        printf(Horseshoe );        break;    }    switch(thirdReel){      case 0:        printf(Bell\n);        break;      case 1:        printf(Cherry\n);        break;      case 2:        printf(Orange\n);        break;      case 3:        printf(Horseshoe\n);        break;    }    // End of switch statements for each reel    loop++;    // Clears the previous printed combination    if (loop < 10)      printf(\e[1;1H\e[2J);    else    {      break;    }  }  // Win/lose conditions  if (loop > 10 && firstReel == secondReel || secondReel == thirdReel){    printf(Congratulations!
