getchar error Yosemite National Park, California

It would be nice if we could safely run the same program on all computers. Trying to make it more succint. [edit] Code: #include #define space ' ' int main(void){ char ch; while ((ch=getchar()) != '\n'){ ch = (ch == space) ? What can I do?C programs are compiled using gcc which itself is written in C so how code for gcc is compiled?What is wrong with the following C code (code blocks What is that "if(c=='')c='0';" line?

It makes it too easy to make mistakes when the program is modified in the future to meet slightly different requirements. It makes sense to have the delimiter character as a parameter: char terminator = 0; string ReadDelimitedString(char marker) { string s = ""; while (true) { int c = getchar(); if Join Date Jan 2003 Posts 1,530 try this Code: #include #define space ' ' int main(void) { char ch = 0; while ((ch = getchar()) != EOF) { if (ch string ReadLine(void) { string s = ""; while (true) { char c = getchar(); if (c=='\n' || c==EOF) break; s=s+c; } return s; } And that really is it this time.

Where are sudo's insults stored? The only things that C++ knows how to add to the ends of strings are plain chars and other strings. On a computer that has unsigned char variables by default, what could the problem be? When we read past the end of the input file, and the value -1 (EOF) is stored in an unsignedchar variable, it takes on the value of 255 (that's the way

On some systems it is -128 to +127, which is fine; but on other systems it is 0 to +255, which is fine for normal ASCII values, but not so hot Except for one thing.

Reading a Comma-Delimited List An almost identical function can be used to read strings that don't necessarily occupy whole lines, but are not delimitted (begun and ended) with spaces.

Declaration Following is the declaration for getchar() function. Very often, we like to leave out unnecessary characters in files to reduce their size and make other processing easier. So, unless the file ends with : (so that it will be seen by the outer loop), the inner loop will spin forever when it hits EOF. This will place the function in the namespace std, so you will also change the invocation to std::getchar() or to use using namespace std;6.1k Views · View UpvotesView More

S. Very simple. EISDIR The open object is a directory, rather than a file. I would probably prefer something like this: void PressEnterToContinue(void) { printf("Press ENTER to continue: "); while (true) { char c=getchar(); if (c=='\n' || c==EOF) break; } } A word about EOF

If a read error occurs, the error indicator for stdin is set and getchar() returns EOF. If you use a const char * as a parameter, that can be either a std::string for C++ or a classic const char *, and the name mangling changes. Equivalent to getc(stdin). The reason is that in C++ you can't know what the symbol name for a function will be; it can be either standard C signature, or mangled C++ signature.

After calling ReadDelimitedString just look at that global variable, if terminator=='\n' then you know that you have finished a whole line of input. kermit: your code works up to a the last character, where it ouputs a characer I don't know.
