Hi i am writing some program where declare 3 stuctures code below


typedef struct Card

char color;
int face;
}CardT;

I have to use scanf function. It is weird because


while(scanf("%s",slowo)!=EOF)

works well in linux

Nothing work properly even if i will compare slowo[0] to 0x1a.

I am using windows. The purpose of this programm is to reading data from input until EOF. Input can be number or characters such as +, - and other arithmetic and bitwise operators. That is the reason...

I don't have to use static variable. I have to use thread. Code for sample test I put below.

I don't understand your answer. Varialbe i is static. It shoul'd keep the value, between function "pusty()" calls.

Hi
I write function that take 5 parameters: pointer to array a, pointer to array b, size of array a, size of array b and pointer to size of result array
My task is to sort first array remove...

Sorry I probably said wrong my task is not print but return as a string. If memory is limited than probably n must be lower than 65536. As I said this is task from codewars site then n must be...

This is task from codewars site so probably n is correct value.
So the way is to calculate perfect bytes of allocated memory? For example


if(n<9)
size=n*(n+1)/2;
if(n>9&&n<=99)...

maximum n size is 2^16 which give us 65 536 so n should be at least 5 characters long


I thought that I don't have to calculate perfect value of characters for each n thats why I allocated bigger...
