I was doing Day 8: Dictionaries and Maps. I think I know how to solve the problem in C++. However I don’t know how can I split string and integer when user input both the string and the integer in the same line. They are separated by two spaces.

Just stream them from std::cin which uses space as a separator:

int n;
std::cin >> n;
for (int i = 0; i < n; ++i) {
    std::string s;
    int a;
    std::cin >> s >> a;
    // process a and s
}

Allow user to input a string variable and integer variable on the , And then the user input string and integer on the same line. def nancysMathFunc(sillyStringInput): func, value = sillyStringInput.split(' ') value� I was doing Day 8: Dictionaries and Maps.

Try something like this:

#include <iostream>
#include <vector>
#include <utility>
#include <string>
#include <sstream>
#include <algorithm>

int main()
{
    std::vector<std::pair<std::string, int>> phoneBook;

    int n;
    std::string line;

    std::getline(std::cin, line);
    std::istringstream(line) >> n;

    for (int i = 0; i < n; ++i)
    {
        std::getline(std::cin, line);
        std::string name;
        int phoneNumber;
        std::istringstream(line) >> name >> phoneNumber;
        phoneBook.push_back(std::make_pair(name, phoneNumber));
    }

    while (std::getline(std::cin, line))
    {
        auto iter = std::find_if(phoneBook.begin(), phoneBook.end(),
            [&](const std::pair<std::string, int> &entry){
                return (entry.first == line);
            }
        );
        if (iter != phoneBook.end())
            std::cout << iter->first << "=" << iter->second << std::endl;
        else
            std::cout << "Not found" << std::endl;
    }

    return 0;
}

On the other hand, if there are never any duplicate names in the phone book, consider using a std::map instead of a std::vector:

Try something like this:

#include <iostream>
#include <map>
#include <string>
#include <sstream>

int main()
{
    std::map<std::string, int> phoneBook;

    int n;
    std::string line;

    std::getline(std::cin, line);
    std::istringstream(line) >> n;

    for (int i = 0; i < n; ++i)
    {
        std::getline(std::cin, line);
        std::string name;
        int phoneNumber;
        std::istringstream(line) >> name >> phoneNumber;
        phoneBook[name] = phoneNumber;
    }

    while (std::getline(std::cin, line))
    {
        auto iter = phoneBook.find(line);
        if (iter != phoneBook.end())
            std::cout << iter->first << "=" << iter->second << std::endl;
        else
            std::cout << "Not found" << std::endl;
    }

    return 0;
}

How to input multiple values from user in one line in Python , For instance, in C we can do something like this: Note that we don't have to explicitly specify split(' ') because split() uses any whitespace One thing to note in above Python code is, both x and y would be of string. Below is complete one line code to read two integer variables from standard input using� Note that we don’t have to explicitly specify split(‘ ‘) because split() uses any whitespace characters as delimiter as default. One thing to note in above Python code is, both x and y would be of string. We can convert them to int using another line

You can also use the standard function, scanf() for taking input from stdin in C, since the input for phonebook entries, name & number, are space-separated.

So, use like the following:

char name[<size>];
int num;
scanf("%s %d", &name, &num);

How to accept multiple integers as input on a single line in Python , A complete one liner: In Python, inputs are strings by default applying a split() function to a Now coming to your question, for single line input you can take the whole input(number of integers How do I return more than 1 integer value in C ? by 7 but are not a multiple of 5, between 2000 and 3200 (both includeded)?. This is a very common scenario when you need to print string and int value in the same line in Python. Printing string and integer value in the same line mean that you are trying to concatenate int value with strings. Some examples: Hey the value of variabe a is 452 You just entered 845. Etc…. Print string and int in the same line in Python

How to split two integers in the same line in python, using input , If you want to split str-formatted integers and make them as int In python3.x we have only input() which converts the argument passed in string. are divisible by 7 but are not a multiple of 5, between 2000 and 3200 (both includeded)? What is a program that takes two integers from users and print whether the first is a� Split a string into tokens - strtok. In this lesson we'll learn how to split a string into several tokens using strtok function. To split a string we need delimiters - delimiters are characters which will be used to split the string. Suppose, we've the following string and we want to extract the individual words.

How to convert a string to an integer in C, The function takes as input the string that is to be converted to an integer. Return value. If successfully executed, the function returns the integer value. If the string � Algorithms. The Workspace browser does not refresh while input is waiting for a response from the user. Therefore, if you run input within a script, the Workspace browser does not display changes made to variables in the workspace until the script finishes running.

Taking input from user : input, raw_input, math library in Python, So, if we give an integer like 5, we will get a string i.e. '5' (a string) and not 5 (int). The 'raw_input()' of Python 2 is same as 'input()' of Python 3 and the 'input()'� Console.ReadLine() expects a sequence of alphanumeric Unicode characters, a String. We can’t assign a String to an Integer variable. The data types don’t match. We will use the ToInt32() method of the Convert class in order to parse our String as an Integer. With this method, we can convert an alphanumeric string into a whole number and be

  • Read the entire line into a string the split it on the spaces?
  • Use std::getline() to read each line, and std::istringstream to parse each line
  • FYI, line breaks also count as ignorable whitespace by operator>>, which is why this code works. However, know that this code is only reading the 1st 4 lines of input, it is not reading the remaining 3 lines. So it does not satisfy the entire requirements of the assignment as documented
  • @RemyLebeau I actually needed help for that only. I know how to solve the problem. I just didn't know how to separate the string and integer when user input both in the same line.
  • You must validate the read as well if (!(cin >> s >> a)) { /* handle error */ }. Whenever you take input, any input, from a file, from the user (and especially from the user) you validate the read succeeds by checking the return (technically the input stream-state here.
  • Any reason for std::map instead of std::unordered_map?
  • @DavidC.Rankin no particular reason
