getline

I do not know much about the sscanf function, but what I am trying to do is iterate through a line of integers. Given the variable char *lineOfInts I have made this the line that registers the users input. I am able to get the input fine, but when I try to use sscanf, I want to iterate through every int. I know that I can account through all the ints if i know how many ints there will be before hand like this.. sscanf(lineOfInts, "%d %d %d..etc", &i, &j, &k...) but what if I don't know how many integers a user will input? How can I account for all of the integers with just one variable? like

I have a text file, "test.txt" which stored my data as follow, there's a spacing between each delimiter field.. Code: Name: Coy 045: Ted: Coy1 054: Red: Coy2 How do i read this data from file and insert this into a vector? vector <Machine> data; Machine machine void testclass(){ ifstream inFile("test.txt"); if (!inFile){ cout << "File couldn't be opened." << endl; return; } while(!inFile.eof()){ string code,name,coy; getline(inFile,code, ':'); getline(inFile,name, ':'); getline(inFile,coy, ':'); data.push_back(machine) } but it seems to have a problem with pushing the data As others have

This question already has an answer here: cin and getline skipping input [duplicate] 4 answers Im doing exercices from c++ primer, and trying to do a program that recieves as input a word and a line. If when i ask for a word (with cin) I press enter, then the program just skips the next lines and doest ask for a line (with the getline)... and if i write an entire phrase in the cin (like "hello beautifull world") then the first word ("hello") is captured by the cin and the others two words ("beautifull world") by the getline. i understand that in the cin, when i input a space, it cuts the input

I'm trying to make a program where the user enters a file name and then the program tries opening it and checks to see if it is open. I am using the getline function. Here is my code so far: #include <iostream> #include <string> #include <fstream> using namespace std; void readGameFile(); int main() { readGameFile(); return 0; } void readGameFile() { ifstream infile; string s; string fileName; getline(cin,fileName); infile.open(fileName); if(infile.is_open()) { cout << "It worked!"<<endl; } else { cout << "You messed up"<<endl; } } It gives me this error: 23:22: error: no matching function for
