C Program to Calculate Pow (x,n)

In this C program, we will calculate the power of a number using the exponentiation operator. We will take the base value ‘x’ and the exponent value ‘n’ from the user, and then calculate the result of x raised to the power of n.

Problem statement

Write a C program to calculate the power of a number using the exponentiation operator.

C Program to Calculate Pow (x,n)

#include<stdio.h>
#include<math.h>

double calculatePower(double x, int n);

int main()
{
    double x;
    int n;
    double result;

    printf("Enter the base value (x): ");
    scanf("%lf", &x);

    printf("Enter the exponent value (n): ");
    scanf("%d", &n);

    result = calculatePower(x, n);

    printf("Result: %.2lf\n", result);

    return 0;
}

double calculatePower(double x, int n)
{
    return pow(x, n);
}

How it works

  1. We include the necessary header files stdio.h and math.h. The stdio.h header file provides input/output functions, and the math.h header file provides mathematical functions such as pow.
  2. We declare a function calculatePower that takes a double value x as the base and an integer value n as the exponent. This function uses the pow function from math.h to calculate and return the result of x raised to the power of n.
  3. In the main function, we declare variables x, n, and result.
  4. We prompt the user to enter the base value (x) and read it using scanf with the %lf format specifier for a double.
  5. We prompt the user to enter the exponent value (n) and read it using scanf with the %d format specifier for an integer.
  6. We call the calculatePower function, passing x and n as arguments, and assign the returned value to the result variable.
  7. Finally, we display the result using printf with the %.2lf format specifier to display the result with two decimal places.
