C Exercises: Compute the sum of the two specified integers. If one of the given integer value is in the range 10..20 inclusive return 18

C-programming basic algorithm: Exercise-22 with Solution

Write a C program to compute the sum of the two given integers. Return 18 if one of the integer values given is in the range 10..20 inclusive.

C Code:

#include <stdio.h>
#include <stdlib.h>

int main(void){
    printf("%d",test(3, 7));
    printf("\n%d",test(10, 11));
    printf("\n%d",test(10, 20));
    printf("\n%d",test(21, 220));
    }       
    int test(int x, int y)
         {
            return (x >= 10 && x <= 20) || (y >= 10 && y <= 20) ? 18 : x + y;
         }

Sample Output:

10
18
18
241

Explanation:

int test(int x, int y) {
  return (x >= 10 && x <= 20) || (y >= 10 && y <= 20) ? 18 : x + y;
}

The function takes two integer arguments x and y, and returns 18 if either x or y is between 10 and 20 (inclusive). Otherwise, it returns the sum of x and y.

Time complexity and space complexity:

The time complexity of this function is O(1) because it only performs a constant number of operations, regardless of the input size.

The space complexity of this function is O(1) because it only uses a constant amount of memory to store the input arguments and the return value.
