C++ Exercises: Reads a sequence of integers and prints mode values of the sequence

C++ Basic: Exercise-71 with Solution

Write a C++ program that reads a sequence of integers and prints the mode values of the sequence. The number of integers is greater than or equal to 1 and less than or equal to 100.
Note: The mode of a set of data values is the value that appears most often.

Sample Solution:

C++ Code :

#include <iostream>
#include <vector>
using namespace std;

int main() {
    vector<int> nums(101, 0);
    int n, mode=0;

    while (cin >> n) {
        nums[n]++;
        if (nums[n] > mode) { mode=nums[n]; }
      }
   
    for (int i = 0; i != nums.size(); ++i) {
        if (nums[i] == mode) 
        {
            cout << i << endl; 
            
        }
    }

    return 0;
}

Previous: Write a C++ program to replace all the lower-case letters of a given string with the corresponding capital letters.
Next: Write a C++ program to which reads n digits chosen from 0 to 9 and counts the number of combinations where the sum of the digits equals to given number. Do not use the same digits in a combination.

C++ Programming: Tips of the Day

Why is there no std::stou?

The most pat answer would be that the C library has no corresponding "strtou", and the C++11 string functions are all just thinly veiled wrappers around the C library functions: The std::sto* functions mirror strto*, and the std::to_string functions use sprintf.
