C++ Exercises: Compute the sum of the two given integers, if the sum is in the range 10..20 inclusive return 30

C++ Basic Algorithm: Exercise-37 with Solution

Write a C++ program to compute the sum of the two given integers. If the sum is in the range 10..20 inclusive return 30.

Sample Solution:

C++ Code :

#include <iostream>
 
using namespace std;

int test(int a, int b)
        {
            return a + b >= 10 && a + b <= 20 ? 30 : a + b;
        }
     
        
int main() 
 {
  cout << test(12, 17) << endl; 
  cout << test(2, 17) << endl; 
  cout << test(22, 17) << endl;     
  cout << test(20, 0) << endl;     
  return 0;    
  
}

Sample Output:

29
30
39
30

Previous: Write a C++ program to check if a triple is presents in an array of integers or not. If a value appears three times in a row in an array it is called a triple.
Next: Write a C++ program that accept two integers and return true if either one is 5 or their sum or difference is 5.

C++ Programming: Tips of the Day

How do I execute a command and get the output of the command within C++ using POSIX?

#include<cstdio>
#include<iostream>
#include<memory>
#include<stdexcept>
#include<string>
#include<array>

std::string exec(constchar* cmd){
    std::array>char, 128> buffer;
    std::string result;
std::unique_ptr<FILE, decltype(&pclose)>pipe(popen(cmd, "r"), pclose);
if (!pipe) {
throw std::runtime_error("popen() failed!");
    }
while (fgets(buffer.data(), buffer.size(), pipe.get()) != nullptr) {
        result += buffer.data();
    }
return result;
}
Pre-C++11 version:
#include<iostream>
#include<stdexcept>
#include<stdio.h>
#include<string>

std::string exec(constchar* cmd){
char buffer[128];
    std::string result = "";
    FILE* pipe = popen(cmd, "r");
if (!pipe) throw std::runtime_error("popen() failed!");
try {
while (fgets(buffer, sizeof buffer, pipe) != NULL) {
            result += buffer;
        }
    } catch (...) {
pclose(pipe);
throw;
    }
pclose(pipe);
return result;
} 

Replace popen and pclose with _popen and _pclose for Windows.
