# C Exercises: Check whether a given temperatures is less than 0 and the other is greater than 100

## C-programming basic algorithm: Exercise-6 with Solution

Write a C program that checks two given temperatures and returns true if one temperature is less than 0 and the other is greater than 100, otherwise it returns false.

**C Code:**

```
#include <stdio.h> // Include standard input/output library
#include <stdlib.h> // Include standard library for absolute value function
int test(int temp1, int temp2); // Declare the function 'test' with two integer parameters
int main(void)
{
// Call the function 'test' with arguments 120 and -1, and print the result
printf("%d", test(120, -1));
// Print a newline for formatting
printf("\n");
// Call the function 'test' with arguments -1 and 120, and print the result
printf("%d", test(-1, 120));
// Print a newline for formatting
printf("\n");
// Call the function 'test' with arguments 2 and 120, and print the result
printf("%d", test(2, 120));
}
// Function definition for 'test'
int test(int temp1, int temp2)
{
// Check if either of the following conditions are true:
// 1. temp1 is less than 0 and temp2 is greater than 100
// 2. temp2 is less than 0 and temp1 is greater than 100
// Return 1 (true) if either condition is true, otherwise return 0 (false).
return temp1 < 0 && temp2 > 100 || temp2 < 0 && temp1 > 100;
}
```

Sample Output:

1 1 0

**Explanation:**

int test(int temp1, int temp2) { return temp1 < 0 && temp2 > 100 || temp2 < 0 && temp1 > 100; }

The above function ‘test’ takes in two integer arguments ‘temp1’ and ‘temp2’. It returns 1 (true) if ‘temp1’ is negative and ‘temp2’ is greater than 100, or if ‘temp2’ is negative and ‘temp1’ is greater than 100, else it returns 0 (false).

**Time complexity and space complexity:**

The time complexity of the function is O(1), which means it takes a constant amount of time to execute, regardless of the input size.

The space complexity of the function is O(1), as it only uses a constant amount of memory, regardless of the input size.

**C Programming Code Editor:**

**Previous:** Write a C program to check whether a given positive number is a multiple of 3 or a multiple of 7.

**Next:** Write a C program to check two given integers whether either of them is in the range 100..200 inclusive.
