How to add a sequence of numbers in a string to an int array with C++

Answer 1

#include <iostream>
#include <sstream>

int AddSequenceOfNumbersInStringToIntArray(int numbers[], const char str[]) {
    std::istringstream iss(str);
    int val, i = 0;

    while (iss >> val) {
        numbers[i++] = val;
    }

    return i;
}

int main() {
    int numbers[128] = { 0 };
    const char str[] = "1 2 78 900 1029 57382";

    int size = AddSequenceOfNumbersInStringToIntArray(numbers, str);

    for (int i = 0; i < size; i++) {
        std::cout << numbers[i] << " ";
    }
}

 
 
/*
run:
 
1 2 78 900 1029 57382
