Is it possible to print a mix of string and integer?

I am new at this so bare with me.

Trying to print to monitor (Serial.println) a mix of text and an integer.
Is it possible.
I know it is possible in a clean C with println("text text &d", int); but it fails.
Using a nano.

thanks

Peter

Is it possible.

Yes

int anInt = 123;
Serial.print("Number ");
Serial.print(anInt);
Serial.println(" on the screen");

Or use the sprintf() sledgehammer

char buffer[30];
int anInt = 123;
sprintf(buffer, "Number %d on the screen", anInt);
Serial.println(buffer);

I have tried the first solution but the result in my mac is the printed in three lines.
Will try your other solution now.

@PICT - nothing to do with your Mac, I'm 99,99% sure you ended up with 3 lines because you used print[color=red]ln[/color] instead of print. The [color=red]ln[/color] piece in the method call means print the text followed by a carriage return character (ASCII 13, or '\r') and a newline character (ASCII 10, or '\n').

I see.

Yes I used Serial.println after watching a lot of tutorials where they only used that command when printing to screen..
But that is very useful information.

thanks a lot

Be aware that it uses a lot more memory than the first one.
Even better use

Serial.print(F("Number "));
Serial.print(anInt);
Serial.println(F(" on the screen"));

Yes I tried it and it used less memory.

Thanks all of you
