Hi, I have this program which you will input a number. It will tell whether which digit is the smallest and which is the biggest and this part works fine. What I can’t get to work is the average part wherein if I input ‘1234’ it will add 1+2+3+4 and divide the sum by 4. if I run this it gives me an output of ‘50’. I also need the ave to be in the form of number and not in ascii form. I can’t seem to find the problem.Please help.Thanks!
char output[5];
int sum=0;
void loop()
{
if (Serial.available() > 0)
{
delay(10);
int x = 0;
while (Serial.available()>0)
{
output[x] = Serial.read();
output[x+1] = '\0';
x++;
}
if (x>=5 || x<4)
{
Serial.println("The input must be 4 bytes.");
}
else
{
int input = atoi(output);
Serial.print("The value is: ");
Serial.println(input);
Serial.print("1st byte is: ");
Serial.println(output[0]);
Serial.print("2nd byte is: ");
Serial.println(output[1]);
Serial.print("3rd byte is: ");
Serial.println(output[2]);
Serial.print("4th byte is: ");
Serial.println(output[3]);
if (min(output[0],output[1])<min(output[2],output[3]))
{
Serial.print("Byte ");
Serial.print(min(output[0],output[1]));
Serial.println(" is the smallest byte.");
}
else
{
Serial.print("Byte ");
Serial.print(min(output[2],output[3]));
Serial.println(" is the smallest byte.");
}
if (max(output[0],output[1])>max(output[2],output[3]))
{
Serial.print("Byte ");
Serial.print(max(output[0],output[1]));
Serial.println(" is the biggest byte.");
}
else
{
Serial.print("Byte ");
Serial.print(max(output[2],output[3]));
Serial.println(" is the biggest byte.");
}
for (x=0;x<5;x++)
{
sum+=output[x];
}
int ave=sum/4;
Serial.println(ave);
}
}
}
