How are you determining that you have a memory leak?
As written, it seems well behaved.
Code:#include <iostream> #include <string> #include <vector> std::vector<std::string> splitStringToVectorArray(const std::string &inputString, const std::string &delimiter) { std::vector<std::string> vectorArray; if (inputString.empty() || delimiter.empty()) { vectorArray.push_back(inputString); return vectorArray; } size_t initiation = 0; size_t position; while ((position = inputString.find(delimiter, initiation)) != std::string::npos) { std::string stringValue = inputString.substr(initiation, position - initiation); if (!stringValue.empty()) { vectorArray.push_back(stringValue); } initiation = position + delimiter.length(); } if (initiation < inputString.length()) { vectorArray.push_back(inputString.substr(initiation)); } return vectorArray; } int main() { std::vector<std::string> parts = splitStringToVectorArray("String1;String2;String3", ";"); std::cout << parts[0] << std::endl; } $ g++ -g baz.cpp $ valgrind ./a.out ==95652== Memcheck, a memory error detector ==95652== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==95652== Using Valgrind-3.15.0 and LibVEX; rerun with -h for copyright info ==95652== Command: ./a.out ==95652== String1 ==95652== ==95652== HEAP SUMMARY: ==95652== in use at exit: 0 bytes in 0 blocks ==95652== total heap usage: 6 allocs, 6 frees, 73,976 bytes allocated ==95652== ==95652== All heap blocks were freed -- no leaks are possible ==95652== ==95652== For lists of detected and suppressed errors, rerun with: -s ==95652== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
