Exit and clrscr not declared in the scope; c lambda functions and parameters; Error: Not declared in scope. XYZ not declared in this scope,expected ';' before X? I keep getting 'not declared in scope' Not declared in this scope, Help! MAXPATHLEN not declared in this scope; Object not declared in this scope(OOP and Header files)? Then for the moment, just take out the clrscr from your code and ignore it. You shouldn't need it anyway. May 31, 2017  Scope of Variables in C In general, the scope is defined as the extent up to which something can be worked with. In programming also the scope of a variable is defined as the extent of the program code within which the variable can we accessed or declared or worked with. This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

Namespaces separate and organize functionality. You can have a 'xander333::sort()' function and it won't conflict with 'std::sort()' or 'boost::sort()' or any other sort(). Without namespaces their can be only one sort().
Now let's say you've put 'using namespace std;' in all your source files and you've implemented a simple templated function called 'fill()' in the global namespace of one of your files. This file also depends on a header from libFoo -- 'foo.hpp'. Version 2.1 of libFoo comes out and all of a sudden your program no longer compiles. You version of 'fill()' suddenly conflicts with another 'fill()'! What happened???
It turns out that the folks implementing libFoo included <algorithm> in the new version of 'foo.hpp' when they didn't before. Now you have all of the standard algorithms being included in your source file, and your 'using namespace std;' has pulled them all into the global namespace. std::fill() now directly conflicts with your fill().
More insidious, you've gotten your code to compile by renaming your fill() to xander333_fill(), but something's not working right -- your report numbers are off. It turns out that your custom divides() function, which does fixed precision math, is no longer being called because the templated function from <functional> (also newly included by 'foo.hpp') makes for a better match because you're calling types did not exactly match the declared types.

You should only really call a function like .c_str if you need to call a legacy C function. In this case atoi is a legacy C function but C++ has plenty of better options that you could use (actually the legacy C standard library has better options to use other than atoi). In a good C++ design you should be avoiding dropping down to C constructs like arrays if at all possible favouring vector<> or array<> instead.
This can be implemented entirely using the C++ library using a stringstream which has the advantage that you cen tell how much of the string has been converted.
  1. #include<iostream>
  2. #include<string>
  3. #include<sstream>
  4. using namespace std;
  5. int main()
  6. {
  7. string str = '131.90';
  8. string leftover;
  9. istringstream iss;
  10. int result;
  11. iss.str(str);
  12. iss >> result;
  13. iss >> leftover;
  14. cout << 'Converted: ' << result << ' Leftover: ' << leftover << endl;
  15. }
Output: Converted: 131 Leftover: .90
By simply changing the type of result to double I can convert the whole string.
