PHP random string generator
To answer this question specifically, two problems: $randstring is not in scope when you echo it. The characters are not getting concatenated together in the loop. Here’s a code snippet with the corrections: Output the random string with the call below: Please note that this generates predictable random strings. If you want to create secure tokens, see … Read more
Can I multiply strings in Java to repeat sequences?
I have something like the following: I’d like to append i “0”s to the someNum string. Does it have some way I can multiply a string to repeat it like Python does? So I could just go: or something similar? Where, in this case, my final result would be: “123000”.
Why am I getting string does not name a type Error?
Your using declaration is in game.cpp, not game.h where you actually declare string variables. You intended to put using namespace std; into the header, above the lines that use string, which would let those lines find the string type defined in the std namespace. As others have pointed out, this is not good practice in headers — everyone who includes that header will also involuntarily hit the using line and import std into their … Read more

Generate random string/characters in JavaScript

Returning string from C function
Either allocate the string on the stack on the caller side and pass it to your function: Or make the string static in getStr: Or allocate the string on the heap:
What does strcmp() exactly return in C?
From the cppreference.com documentation Return value Negative value if lhs appears before rhs in lexicographical order. Zero if lhs and rhs compare equal. Positive value if lhs appears after rhs in lexicographical order. As you can see it just says negative, zero or positive. You can’t count on anything else. The site you linked isn’t incorrect. … Read more
Why use string::iterator rather than index?
The index can only be used for containers that support random access – direct access to a given position. The iterator offers a unified way to access any collection/data structure. The flexibility when refactoring your code is immense.
How do I tokenize a string in C++?
C++ standard library algorithms are pretty universally based around iterators rather than concrete containers. Unfortunately this makes it hard to provide a Java-like split function in the C++ standard library, even though nobody argues that this would be convenient. But what would its return type be? std::vector<std::basic_string<…>>? Maybe, but then we’re forced to perform (potentially redundant and costly) … Read more
