ABS()

Calculates the absolute value of a number

#include <iostream>
#include <cmath> // for sqrt, pow, ceil, floor, abs

using namespace std;

int main() {
    // 1. Square root of a number
    double num1 = 25.0;
    double squareRootResult = sqrt(num1);

    // 2. Absolute value of a number
    int num2 = -42;
    int absoluteValueResult = abs(num2);

    // 3. Power of a number
    double base = 2.0, exponent = 3.0;
    double powerResult = pow(base, exponent);

    // 4. Ceiling and Floor of a number
    double num3 = 3.7;
    double ceilResult = ceil(num3);
    double floorResult = floor(num3);

    // Display results
    cout << "Square root of " << num1 << " = " << squareRootResult << endl;
    cout << "Absolute value of " << num2 << " = " << absoluteValueResult << endl;
    cout << base << " raised to the power of " << exponent << " = " << powerResult << endl;
    cout << "Ceiling of " << num3 << " = " << ceilResult << endl;
    cout << "Floor of " << num3 << " = " << floorResult << endl;

    return 0;
