How do I resolve 'no matching function for call to' in C++?

In C++, the error 'no matching function for call to' typically occurs when you attempt to call a function with the wrong argument types or number of arguments. This means that the function you're trying to call does not exist with the signature you've provided. Here is how you can resolve this error:

Example

Consider the following example where we define a function and try to call it incorrectly:

// Example of C++ code causing no matching function error #include void display(int a) { std::cout << "The value is: " << a << std::endl; } int main() { // Incorrect function call display(); // Error: no matching function for call to 'display()' return 0; }

To fix the error, you need to ensure that the function call matches the function's signature. The corrected call would be:

int main() { // Correct function call display(10); // Calls display with an integer return 0; }
