Warning C26494

  • Статия

Variable 'variable' is uninitialized. Always initialize an object.

Remarks

This check requires local variables to be initialized at the declaration or in the following statement.

Example

#include <iostream>
void function()
{
    int myVal; // C26494, Variable is uninitialized
    std::cout << myVal; // C6001
}

To fix the issue, initialize the variable at the declaration.

#include <iostream>
void function()
{
    int myVal{};
    std::cout << myVal;
}
