error stray 253 in program c

I wrote up a string of code that checks if a given number n , is prime or not, and returns true or false accordingly.

When I try to compile it using cygwin with g++ std=c++11 -o PrimeChecker.cpp it gives me a whole lot of errors such as stray ‘253’ in program and stray ‘302’ in program on lines 15, 22, 30 (which are all the lines with the cout statements)

I do not understand what is wrong here. It looks to me as if I have everything written correctly.

К сабжу не относится, но у вас странное представление о чтении файла:
setlocale(LC_ALL,»Russian»);//Чтение файла

А если по делу, проверьте что у вас после cout стоит >> вместо »


I wrote a program using nano and tried to compile it using gcc command on Lx-terminal. It’s showing stray error. Can anyone tell me what is the problem? For simple «hello world» program also is showing errors.

The problem is with your printf line.

you are missing the closing parenthesis «)«, You are also missing quotes around the text «Hello World»

change that line to:

Your final code should look like this

You can then compile it with this command:

You should now have an executable called helloworld that can be run by typing:
