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


Sum of Integers, Return 30 in Range 10–20

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;

// Function to calculate and return a modified sum based on certain conditions
int test(int a, int b)
{
    // Check if the sum of 'a' and 'b' is between 10 and 20 inclusive
    // If true, return 30; otherwise, return the sum of 'a' and 'b'
    return (a + b >= 10 && a + b <= 20) ? 30 : a + b;
}

int main() 
{
    // Test cases to check different scenarios of the test function
    cout << test(12, 17) << endl;
    cout << test(2, 17) << endl;
    cout << test(22, 17) << endl;
    cout << test(20, 0) << endl;

    return 0; // Return 0 to indicate successful completion
}

Sample Output:

29
30
39
30

For more Practice: Solve these Related Problems:

  • Write a C++ program to compute the sum of two integers, but if the sum falls within the range 10 to 20 inclusive, output 30 instead.
  • Write a C++ program that reads two numbers, calculates their sum, and returns 30 if the sum is between 10 and 20, otherwise returns the sum.
  • Write a C++ program to add two integers and check if the result lies between 10 and 20, in which case it outputs 30, else prints the computed sum.
  • Write a C++ program that conditionally modifies the sum of two numbers: if the sum is in the range 10–20, return 30; otherwise, return the original sum.

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.
