How to solve C++ syntax error: 'expected initializer before '

How to solve C syntax error: 'expected initializer before '

In C programming, various errors are often encountered. One of the common errors is "expected initializer before '

First, let’s look at a code example to better understand this error:

template <typename T>
void PrintVector(vector<T> vec) {
    for (const auto& elem : vec) {
        cout << elem << " ";
    }
    cout << endl;
}

int main() {
    vector<int> myVector = {1, 2, 3, 4, 5};
    PrintVector<int>(myVector);
    return 0;
}

In the above code, we define a template function PrintVector that accepts a vector object and Print its elements. In the main function, we create a vector object containing integers and pass it to the PrintVector function. However, when we try to compile this code, we get the following error message: "expected initializer before '

The reason for this error is that the compiler does not recognize the "

It is very simple to solve this error. We only need to add the keyword "template" before the "

template <typename T>
void PrintVector(vector<T> vec) {
    for (const auto& elem : vec) {
        cout << elem << " ";
    }
    cout << endl;
}

int main() {
    vector<int> myVector = {1, 2, 3, 4, 5};
    PrintVector<int>(myVector);
    return 0;
}

Now, we have added the "template" keyword to tell the compiler that "

After correcting the error, recompile the code and you will get the output we expect. This is how to solve the C syntax error "expected initializer before '

To summarize, when you encounter the error message "expected initializer before '
