void uart_send_string(volatile uint8_t * str)

while (*str)

}
}
Merve
but ı cant send 0 value, and ı should to send 0 value
Merve
do you have any suggestion?
Suka
but ı cant send 0 value, and ı should to send 0 value
you must sent 0 as "0" not as integer 0
Merve
oh you mean character?
Merve
volatile uint8_t s2dizi[4]= {"0",0x80,0x01,0xFF,0x3A}
Merve
it is not currect ı think
Suka
oh you mean character?
string as in {'0',0} if you sent char ig it will error because while loop seeking 0 to stop
Suka
volatile uint8_t s2dizi[4]= {"0",0x80,0x01,0xFF,0x3A}
you must add 0 at the end of array
Merve
I want to divide the series as well
Merve
Merve
what should ı do
Suka
I want to divide the series as well
if you want to sent array of int you must also tell your function about your data length
like
send_uart(int *data, int len)
Merve
Is it my array send function?
Suka
but if you feed string and want your function to send integer you can
transmit(*str++ - '0') but this only valid for string of number only
Suka
Is it my array send function?
void uart_send_string(volatile uint8_t * str, int len)
{
while (len--)
{
UART_Transmit(*str++);
}
}
perhaps something like this

scanf("%c",&c);
got it next problem
input
#include <stdio.h>
void main()
{
int length,breadth,area; 4
printf("enter the length of rectangle");
scanf("%d\n is the length",&length);
printf("enter the breadth of rectangle");
scanf("%d\n is the breadth",&breadth);
area=length*breadth;
printf("%d is the area of rectangle",&area);
}
output
enter the length of rectangle4
4
enter the breadth of rectangle4
6422292 is the area of rectangle

so 1why i need to give 2 no.s in length?
and the area is ????/how

for printf you don't need & if you do it will print the address of variable not the value.

Create Player.h and Player.cpp C++ only. to implement the below. You will also need to create a Player playerDriver.cpp class as described file to test your Player class implementation. The Player class has the following attributes: Data Members (private): : string : name double The player’s name points The player’s points Member functions (public): Default constructor Set name to an empty string points Parameterized constructor to value 0. Takes a string and and double assigning this order getName() name and Returns the player’s points , in name string getPoints() Returns the player’s as a points double setName(string) Sets the player’s as a name returns nothing) setPoints(double) Sets the player’s (and points returns nothing) (and

Different b/w void main and int main

in void main (), the function cannot return any integer value. on the other hand int main() has a benefit of returning any integer value .. simple .

If id should be int, you don't need to put it in single quotes.

... where id='13'
Good
... where id=13
