stoi cpp
stoi() is a function in C++ that converts a string to an integer.
Here's a simple explanation of how it works: - The function stoi() takes a string as input and converts it into an integer. - It stops converting when it encounters a non-numeric character. - If the input string is empty or doesn't contain any valid integer representation, stoi() throws an exception of type invalid_argument or out_of_range.
For example:
#include <iostream>
#include <string>
int main() {
std::string str = "12345";
int num = std::stoi(str);
std::cout << "The converted integer is: " << num << std::endl;
return 0;
}
