    Cool Simple reset counter on for loop

    Please, if you have the time and run and compile this program, I am looking for further instruction from someone on game_loop variable to countdown from 3 to 0 (reset it). I've tried with a while loop before and after the for () loop with no success. After three successful tries followed by a failure, and an "y" to continue with another game, just says "you have 1 try left", i'm looking for a way to reset the game_loop variable to reset it to start at 3 again, but it's broke. I've tried with this:


    Code:
    if (game_loop <= 1)
    {
        game_loop += 3;
    }

    I don't even know if the above is valid C but i also tried messing around with a while loop similar to what I did in the main body of the program to no available. Please direct me further.

    Code:
    
    #include <stdio.h>
    #include <stdlib.h>
    #include <time.h>
    #include <ctype.h>
    
    
    void delay (int seconds)     // delay function i got this source code from google
    {
        unsigned long int count=333333333, i, j;
    
    
        for(i = 0;i<seconds;i++)
            for(j = 0; j < count; j++);
    }
    
    
    int main (void)
    {
        char c = ' ';  // fill console with blank space to clear screen
        int successful_tries = 0;
        //char newgame = 0;
        int num = 0;
        int input = 0;
        int limit = 9;
        char get_input;
        int limit_2 = 1;
        int game_loop = 3;
        
        printf("This is a game to test your memory, with a random number of 1 digit that will be displayed a max of 3 successive times.\n");
    
    
        do
        {
            clock_t t;
            t = clock();
    
    
            for (; game_loop > 0; --game_loop) // count down how many tries left until program ends
            {
    
    
                // code to compute random digits
                 srand(time(NULL));
                num = limit_2 + rand() % limit;
    
    
                printf("\n%d\n", num);
                delay(1);     // create 1 second program delay before clear screen with 'X's
    
    
                // clear screen with x's
                for (int ctr_1 = 1; ctr_1 < 7500; ctr_1++)
                {
                    printf("%c", c);
                }
        
                printf("\n\n");
    
    
                printf("\nYou have %d tr%s left.\n", game_loop, game_loop == 1 ? "y" : "ies");
                printf("What sequence was displayed?: ");
                scanf("%d", &input);
    
    
                if (input == num) // if correct match
                {
                    printf("Correct Answer!\n");
    
    
                    int i = 0;
    
    
                    while (i < 1)  // per one match (one correct match)
                    {
                        successful_tries += 1; // Successful tries for end of program
                        ++i;
                    }
    
    
                    if (successful_tries == 3) // sequence was inserted 3 times in a row
                    {
                        limit += 191; // make sequence 3 digits
                        limit_2 += 49;  // limit_2 = limit_2 + 49;
                    }
    
    
                    if (successful_tries >= 3)
                    {
                        game_loop += 1;
                    }
                }
        
                if (input != num)
                {
                    printf("You entered an incorrect match!\n");
                    break;
                }
            }
    
    
        // The program will then calculate a score based on the number of successful tries and the time taken and invite the player to play again.
        t = clock() - t;
    
    
        double program_execution = ((double)t)/CLOCKS_PER_SEC; // in seconds
    
    
        printf("You had %d successful tr%s. Program execution took %f seconds.\n", successful_tries, successful_tries == 1 ? "y" : "ies", program_execution);
    
    
        printf("Do you want to play another game? y for yes n for no\n");
    
    
        scanf(" %c", &get_input);
    
    
        if (tolower(get_input) == 'n') // if 'n' is inserted
        {
            printf("You entered %c\nProgram will end...\n", get_input);
            return 0;
        }
        
        } while (tolower(get_input) == 'y');
        
        return 0;

    Code:
    // etc... code ;
    
    do {
      clock_t t; 
      t = clock();
    
    
      game_loop = 3; 
      successful_tries = 0;
    
    
      for (; game_loop > 0; --game_loop) {
        // etc... code ;
      }
    
    
      // etc... code ;
    
    
    }  while (tolower(get_input) == 'y');
    
    // etc... code ;
    "without goto we would be wtf'd"

    Thanks Structure, took a few days for someone to post. Looks like I was just missing that one line:

    Code:
    successful_tries = 0;

    Please, put srand(time(NULL)) outside the loop. Inside you risk not getting "random" values with rand(). The seed must be provided only once in your program.
