How to add a binary string to an int64 array as an integer value in C++

Answer 1

#include <iostream>
#include <string>
#include <cstdint> // for int64_t

int main() {
    std::string binaryString = "100111101101";
    
    int intValue = std::stoi(binaryString, nullptr, 2);

    int64_t intArray[1]; 
    intArray[0] = static_cast<int64_t>(intValue);

    std::cout << "64-bit integer value: " << intArray[0] << std::endl;
}



 
/*
run:
 
64-bit integer value: 2541
