i was searching on this forum (and not only) and i couldnt find my answer anywhere,
i only saw strncat fuction that is for strings
so

i have :
int temp_1=5;
int temp_2=6;
int temp_2=9;

int temp_3;

I want the temp_3 to have the 569 value, (something like temp_1 & temp_2 & temp_3)

any solution?

int temp_1=5;
int temp_2=6;
int temp_3=9;

int temp_3 =  (temp_1*100) + (temp_2*10) + (temp_3); // 569
3 
int temp_4 = (temp_1 * 100) + (temp_2 * 10) + temp_3;

If you are reading this in as serial data, multiply the previous value by 10 before adding the new value.

int aVal = 0;
char aChar = Serial.read();
if(aChar >= '0' && aChar <= '9')
{
   aVal *= 10;
   aVal += aCahr - '0';
}
