Daily practice——Randomly generate an integer between 1-100 and see how many times you can guess.Requirements: The number of guesses cannot exceed 7 times, and after each guess, it will prompt "bigger"

Title: Randomly generate an integer between 1-100 and see how many times you can guess.Requirements: The number of guesses cannot exceed 7 times, and after each guess, it will prompt "bigger" or "smaller".

The key to solving the problem:The control of the number of guesses and the number of guesses

Ideas:1. Generate random numbers

2. Prompt the number of times you can guess

3.while judging the number of guesses

4. Judge whether the guessing opportunities are used up

Process: Next, we will write the code step by step according to our problem-solving ideas

    1. Generate random numbers
    Scanner sc = new Scanner(System.in);
      int num = (int)(Math.random()*99 +1);
    2. Prompt the number of guesses
    System.out.println("You can't guess more than 7 times");
      int i = 1;//Start isThe first time
    3.while judging the number of guesses
    while(i < 8){
System.out.println("Please guess an integer between 1-100");
int guessNum = sc.nextInt();
System.out.println("The number you entered is:" + guessNum);
if(guessNum < num){
System.out.println("The number you entered is too small");
}else if( guessNum > num){
System.out.println("The number you entered is too big");
      }else{
System.out.println("Congratulations, you guessed correctly, you are in the "+i+"th guess");
        break;
      }
    i++;
        4. Determine whether the guessing opportunities are used up
      if(i == 8){
System.out.println("Unfortunately, you ran out of 7 chances and you didn't guess correctly");
System.out.println("The random number is:"+ num);
     

The full results are as follows:

  For your convenience, the source code is attached below:

//1. Generate random numbersScanner sc = new Scanner(System.in);int num = (int)(Math.random()*99 +1);//System.out.println("The randomly generated number is: " + num);//2. Prompt the number of times you can guessSystem.out.println("You can't guess more than 7 times");int i = 1;//Start is the first time//3.while judge the number of guesseswhile(i < 8){System.out.println("Please guess an integer between 1-100");int guessNum = sc.nextInt();System.out.println("The number you entered is: " + guessNum);if(guessNum < num){System.out.println("The number you entered is too small");}else if( guessNum > num){System.out.println("The number you entered is too big");}else{System.out.println("Congratulations, you guessed it right, you guessed it in the "+i+"th time");break;}i++;//4. Determine whether the guessing opportunities are used upif(i == 8){System.out.println("Unfortunately, you ran out of 7 chances and you didn't guess correctly");System.out.println("The random number is: " + num);}}

Summary:

     The key to this question is the judgment of the number of guesses (the guess is not successful after seven guesses) and the number of guesses

Tomorrow's practice:There are n integers, so that the previous numbers are moved back m positions in order, and the last m number becomes the mostThe number of m in front
