will be helpful for those in need Simply reads each character one by one with getchar and prints immediately with putchar. When encounters a dot (.), prints it and then terminates. Hence it doesn't store more than a single character at a time.
do-while loop

Hope that helps In the line you indicated, temp needs to be used because it's giving you information about the current number being read in (basically it's either -1 if it was a dot or the accumulated number if it was a number : temp = 10*temp + (ch-'0');).
Obviously, you can't just be looking at ch because then you'd have no way to check if the number was too high (IP-type numbers need to be from 0 to 255).
what should i do to display all data from 2 or more different table, i try to use JOIN but i still dont understand?

To fix the issue you can do One way you could connect these 2 tables and display all of the data in them by using JOIN is like this:
code :
SELECT table1.*, table2.* FROM data_skm_organisasi AS table1
LEFT JOIN data_skm_kejuaraan AS table2 ON table1.namaKegiatan = table2.namaKegiatan AND table1.namaMahasiswa AND table2.namaMahasiswa
ORDER BY table1.id ASC
My code dont see a whille loop in C (with a getchar function)

hope this fix your issue With both scanf() and getchar(), you generally have to press the [return] key after the desired key. Both the desired key, and the return key, are (usually) placed in the stdin stream. The question code neglected to take this in consideration. Hence, the first desired key was read by scanf() and stored in num, but left the return key '\n' in the buffer; which was then later read by the getchar() and stored in c. Hence the loop exit criteria was satisfied, and the program terminated.
Somehow, the code, to be functional, must read the unwanted return key '\n' left behind by the call to scanf(); and perhaps also for the getchar().
code :
#include <stdio.h>
#include <ctype.h>

int main()
{
    int num;
    int c;
    char cr[2];
    printf("Enter number: \n");
    scanf("%d%1[\n]", &num, cr);  // Reads %d into num, and garbage '\n' into cr.
    printf("Enter a string : \n");
    while((c = getchar()) != '\n')
    {
        if(isdigit(c))
            putchar(c);
        else
            putchar(c + num);
        getchar(); // Reads garbage '\n' from previous getchar()
    }
    printf("\n");
    return 0;
}

Hope that helps For your first question, Subclasses can call super class constructors with a call to super()
i.e.

fixed the issue. Will look into that further Basically the line super(int health, int strength, int speed, int type); keeps giving me an error that says... , Remove type of parameters and add parameters to class constructor.
