Getting all services and their path to exe - c++

Question

Get list of windows services and print name, status, path to exe
the above statement needs to be solved, I am aware we enum services to find.....since I am beginner ,I don't understand how to retrieve all the path to exe.
this is what I knew
#include <Windows.h>
#include <iostream>
int main()
{
SC_HANDLE sHandle;
LPQUERY_SERVICE_CONFIG lpServiceConfig = NULL;
DWORD cbBufSize = 100;
LPDWORD bytesNeeded = NULL;
sHandle = OpenSCManager(NULL,NULL,SC_MANAGER_ALL_ACCESS);
sHandle = OpenService(sHandle, "YOU SERVICE NAME",SERVICE_ALL_ACCESS);
QueryServiceConfig(sHandle,lpServiceConfig,cbBufSize,bytesNeeded);
std::cout << lpServiceConfig->lpBinaryPathName << std::endl;
}

You need to use EnumServiceStatus() to query which services are installed. You can then open each service to query its EXE path.
Also, your code is leaking resources and memory.
Try something more like this:
#include <Windows.h>
#include <iostream>
#include <vector>
int main()
{
DWORD bytesNeeded = 0;
DWORD numServices = 0;
DWORD resumeHandle = 0;
SC_HANDLE hSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_ENUMERATE_SERVICE);
if (!hSCManager) ...
EnumServicesStatus(hSCManager, SERVICE_WIN32, SERVICE_STATE_ALL, NULL, 0, &bytesNeeded, &numServices, &resumeHandle);
if (GetLastError() != ERROR_INSUFFICIENT_BUFFER) ...
std::vector<BYTE> enumBuffer(bytesNeeded);
LPENUM_SERVICE_STATUS pEnum = reinterpret_cast<LPENUM_SERVICE_STATUS>(enumBuffer.data());
if (!EnumServicesStatus(hSCManager, SERVICE_WIN32, SERVICE_STATE_ALL, pEnum, bytesNeeded, &bytesNeeded, &numServices, &resumeHandle)) ...
for(DWORD idx = 0; idx < numServices; ++idx)
{
std::cout << pEnum[idx].lpServiceName << " (" << pEnum[idx].lpDisplayName << ")" << std::endl;
// use/display pEnum[idx].ServiceStatus as needed ...
SC_HANDLE hService = OpenService(hSCManager, pEnum[idx].lpServiceName, SERVICE_QUERY_CONFIG);
if (!hService) ...
QueryServiceConfig(hSerivce, NULL, 0, &bytesNeeded);
if (GetLastError() != ERROR_INSUFFICIENT_BUFFER) ...
std::vector<BYTE> configBuffer(bytesNeeded);
LPQUERY_SERVICE_CONFIG lpServiceConfig = reinterpret_cast<LPQUERY_SERVICE_CONFIG>(configBuffer.data());
if (!QueryServiceConfig(hSerivce, lpServiceConfig, bytesNeeded, &bytesNeeded)) ...
std::cout << lpServiceConfig->lpBinaryPathName << std::endl;
CloseServiceHandle(hService);
}
CloseServiceHandle(hSCManager);
}
