how to code string to int converter c++
To code a string to int converter in C++, you can use the stoi
function from the <string>
library. Here are the steps to implement it:
Include the necessary header files:
cpp #include <iostream> #include <string>
These header files are required for input/output operations and string manipulation.Declare a string variable to hold the input string:
cpp std::string input;
Get the input string from the user:
cpp std::cout << "Enter a number as a string: "; std::cin >> input;
Convert the string to an integer using the
stoi
function:cpp int number = std::stoi(input);
The stoi
function takes the input string as an argument and returns the corresponding integer value.
- Display the converted integer:
cpp std::cout << "The converted integer is: " << number << std::endl;
This step is optional but can be included to verify the correctness of the conversion.
And that's it! You have successfully coded a string to int converter in C++ using the stoi
function.
