# C Exercises: Compute the sum of the two given integers. If the sum is in the range 10..20 inclusive return 30

## C-programming basic algorithm: Exercise-17 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.

**C Code:**

```
#include <stdio.h> // Include standard input/output library
#include <stdlib.h> // Include standard library for additional functions
// Function declaration for 'test' with two integer parameters
int test(int a, int b);
int main(void){
// Print the result of calling 'test' with different integer values and format the output
printf("%d",test(12, 17));
printf("\n%d",test(2, 17));
printf("\n%d",test(22, 17));
printf("\n%d",test(20, 0));
}
// Function definition for 'test'
int test(int a, int b)
{
// Check if the sum of 'a' and 'b' is between 10 and 20 (inclusive)
if (a + b >= 10 && a + b <= 20) {
return 30; // If the condition is met, return 30
} else {
return a + b; // If not, return the sum of 'a' and 'b'
}
}
```

Sample Output:

29 30 39 30

**Explanation:**

int test(int a, int b) { return a + b >= 10 && a + b <= 20 ? 30 : a + b; }

The said function takes two integers 'a' and 'b' as input parameters and returns an integer value. The function first checks if the sum of 'a' and 'b' is between 10 and 20 (inclusive). If yes, then it returns the value 30, otherwise, it returns the sum of 'a' and 'b'.

**Time complexity and space complexity:**

The time complexity of the function is O(1) as the function has constant time complexity, as the execution time is not dependent on the size of the inputs.

The space complexity of the function is O(1) as the function has constant space complexity and it does not use any extra space apart from the input parameters and the return value.

**Pictorial Presentation:**

**Flowchart:**

**C Programming Code Editor:**

**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.
