How to convert numeric value of a string to int in c++?
So I've a string, "12|24|64" ,I want to store "12" ,"24"and "64" into an int array, Apparently I've to skip "|".
I want to store "12" in 0th index, "24" in 1st index and "64" in 2nd index.
How can I do so? I've tried, But instead it's storing sum-https://code.sololearn.com/cjSagFdSfw47/?ref=app
By default getline(ss, str) would read until new line
Default delimiter = '\n'
but if you say you want to read until a slash
You have to set the delimiter yourself
The arguments it takes are
input stream, string and delimiter
It reads input stream while it doesn't get to the delimiter and stores it in the string
It can be used with std::cin and std::ifstream because those are input streams as well
There is no option like that but you can do something else
std::stringstream ss("2-2|24|25");
char del1 = '|', del2 = '-';
std::string str;
while(std::getline(ss, str, del1)) {
std::stringstream temp(str);
while(std::getline(temp, str, del2)) {
std::cout << str << std::endl;
}
}
Here is an example where I used strtok to look for any of three delimiters:

And here is how I did the same task in C++, but without strtok. I used string find instead, after determining which single delimiter to look for:
