Compare double* with double

To compare a double* (pointer to a double) with a double value in C++, you need to dereference the pointer to access the value it points to. Here's an example of how you can compare them:

cppCopy code
double* ptr = ...; // Your double pointer

double value = ...; // The double value you want to compare



// Compare the double value pointed to by the pointer with the given value

if (*ptr == value) {

    // The values are equal

} else {

    // The values are not equal

}

In the above code, the *ptr expression is used to dereference the pointer and obtain the double value it points to. This value is then compared with the value variable using the == operator.

Keep in mind that when working with pointers, it's important to ensure that the pointer is valid and points to a valid memory location before dereferencing it. If the pointer is not initialized or points to an invalid memory location, accessing its value can lead to undefined behavior.
