c++ set value to inf

To set a value to infinity in C++, you can use the std::numeric_limits library. Here are the steps to do so:

1. Include the <limits> header file at the beginning of your code to access the numeric_limits class.

2. Declare a variable of the desired data type that you want to set to infinity. For example, if you want to set a float variable to infinity, you can declare it as follows:

cpp float myFloat;

1. Assign the value of infinity to the variable using the std::numeric_limits class. For example:

cpp myFloat = std::numeric_limits<float>::infinity();

In this example, std::numeric_limits<float> returns the limits for the float data type, and the infinity() member function returns the value of positive infinity.

If you want to set a variable of a different data type to infinity, simply replace float with the desired data type, such as double or int.

That's it! Now your variable myFloat has been set to infinity. Remember to include the necessary header file and use the appropriate data type for your specific use case.
