Conclusion string::npos is a useful constant for string manipulation in C++, especially when working with functions like find that may return an invalid position. It's important to understand how and when to use
But with examples I understand more.Well for the following things, try to have a look at reference and to understand it: functions : http://www.cplusplus.com/doc/tutorial/functions/ arrays :http://www.cplusplus.com/doc/tutorial/arrays/ statement and flow control : http://www.cplusplus.com...

ok so when using it i need to avoid using anything in the standard namespace, like pre-defined common functions etc. (toupper, aoti, etc. ) and i'm predefined classes like the c++ string class.. am i right? Mar 9, 2012 at 6:00am ...
Also, your loop as it is needs a bit of rework to find vowels[i], not 'a', and you'll need an inner loop to repeat the find/erase combination until all examples of that character are gone, not just the first one. [Edit] Oh, and make sure you check the returned f1 value from...
Standard C library gives us a set of utility functions such as: /*returns the length of the string*/ int strlen(const char*); /*copies the 2nd string into the 1st*/ char* strcpy(char*, const char*); /*compares two strings*/ ...
