Compilation error: stray ‘\302’ in program, etc
(12 answers)
Closed last month.
I'm getting these errors in my program after pasting in some code:
showdata.cpp:66: error: stray ‘\342’ in program
showdata.cpp:66: error: stray ‘\200’ in program
showdata.cpp:66: error: stray ‘\235’ in program
showdata.cpp:66: error: stray ‘\’ in program
showdata.cpp:66: error: stray ‘\342’ in program
showdata.cpp:66: error: stray ‘\200’ in program
showdata.cpp:66: error: stray ‘\235’ in program
showdata.cpp:67: error: stray ‘\342’ in program
showdata.cpp:67: error: stray ‘\200’ in program
showdata.cpp:67: error: stray ‘\235’ in program
showdata.cpp:67: error: stray ‘\’ in program
showdata.cpp:67: error: stray ‘\342’ in program
showdata.cpp:67: error: stray ‘\200’ in program
showdata.cpp:67: error: stray ‘\235’ in program
Here are the two lines that are causing the errors.
size_t startpos = str.find_first_not_of(” \t”);
size_t endpos = str.find_last_not_of(” \t”);
How can I fix this?
The symbol ” is not ". Those are called 'smart quotes' and are usually found in rich documents or blogs.
The lines
size_t startpos = str.find_first_not_of(” \t”);
size_t endpos = str.find_last_not_of(” \t”);
have some "special" kind of double quotes, try the following:
size_t startpos = str.find_first_not_of(" \t");
size_t endpos = str.find_last_not_of(" \t");
This sort of error message, error: stray ‘\xyz’ in program, can appear with any other character or symbol that is not recognized by the compiler as a legal one.
Sharing my personal experience:
- bool less<const char∗>(const char∗ a, const char∗ b)
- bool less<const char*>(const char* a, const char* b)
The former one is copy-pasted from a PDF file. It doesn't compile.
The latter one compiles as expected.
You can use the sed command to fix these issues.
This will give you a quick preview of what will be replaced.
sed s/[”“]/'"'/g File.txt
This will do the replacements and put the replacement in a new file called WithoutSmartQuotes.txt.
sed s/[”“]/'"'/g File.txt > WithoutSmartQuotes.txt
This will overwrite the original file.
sed -i ".bk" s/[”“]/'"'/g File.txt

This is the written code
#include <iostream>
int main(){
std::cout << "Hello World" << std::endl;
return 0;
}
I revised the code you have posted as well as added a piece of code to utilize the namespace std. Analyzing the output from your compiler it does seem that you may have not added a semi colon. Alternatively, it's not necessary to reference the std library when calling it's functions but it's up to your preference. It doesn't seem though to be an issue with your code either. Can you post the actual code you've attempted to compile because there doesn't seem to be an issue with this piece.
Revised Code:
#include <iostream>
using namespace std;
int main() {
std::cout << "Hello World" << std::endl;
return 0;
}

All errors here explained with messages though i don't get it exactly what is wrong.
Which functions get called when you send 0 as argument
The call is ambiguous. Neither function is preferred by the overload resolution, since 0 is both an int literal, as well as a pointer literal. An ambiguous call makes the program ill-formed, so a compiler is not required to accept it. This is what the compiler told you:
error: call of overloaded ‘func_print(NULL)’ is ambiguous
std::cout << “void” << std::endl;
This is wrong, because “ (Left Double Quotation Mark) is not a valid character there. You've most likely attempted to write a string literal. A string literal uses the " (Quotation Mark) character, which is similar. This is what the compiler told you:
error: expected primary-expression before ‘void’
It doesnt have any include or headers it should compile by its own (supposedly)
Your supposition is wrong. Besides the problems mentioned earlier, std::cout (or anything else from the std namespace) cannot be used without including standard headers.

I am new in both Octave and C++ ! I want to use Octave in C++ and found this webpage. I started with the upper code and tried to run it. Unfortunately there is no document on this matter and I encountered with a lot of errors. I first used msvc 2010 and found that the I should use gcc!! Here are what I'v done so far:
Download Octave from this link, (I download octave-4.0.0_0.zip)
I tried to compile this code:
int main (void)
{
std::cout << "Hello Octave world!\n";
int n = 2;
Matrix a_matrix = Matrix (n, n);
for (octave_idx_type i = 0; i < n; i++)
for (octave_idx_type j = 0; j < n; j++)
a_matrix(i,j) = (i + 1) * 10 + (j + 1);
std::cout << a_matrix;
return 0;
}
I also included: 1) iostream and 2) octave directory: N:\octave-4.0.0\include\octave-4.0.0\octave\oct.h
I got this error in msvc10:
1>n:\octave-4.0.0\include\math.h(169): error C2065: 'asm' : undeclared identifier

I really appreciate any help!
Octave > 4.0 is using msys and gcc in thein windows, but you don't really need to know that in order to get it to compile.
Looking at what you are trying to do, your are using a IDE other than octave to try to compile the code without then including the octave paths and octave libraries correctly.
The easiest way is to use octave to do it.
Firstly you will need to include the octave header, and since you are using cout, iostream:
#include <octave/oct.h>
#include <iostream>
Then from octave us the mkoctfile command with the --link-stand-alone option as shown in the link you referenced.
mkoctfile --link-stand-alone main.cpp
