string to size_t cpp

To convert a string to size_t in C++, you can follow these steps:

1. Include the necessary header file: #include <string>

2. Declare a string variable to hold the input value: std::string inputString;

3. Get the input value from the user or assign it to the inputString variable.

4. Use the std::stoi function to convert the string to an int value: int intValue = std::stoi(inputString);

5. Finally, cast the int value to size_t using a static cast: size_t sizeValue = static_cast<size_t>(intValue);

Now, the sizeValue variable holds the size_t value converted from the string input.
