Power series of 3 using c programming language

• Include Libraries:

  • #include <stdio.h>: This includes the standard input-output library for functions like printf.
  • #include <math.h>: This includes the math library for mathematical functions like pow.

• Main Function:

  • void main(): The main function where the execution of the program begins.

• Variable Declarations:

  • int i, m: Two integer variables i and m are declared. i will be used as the loop counter, and m will store the result of the power calculation.

• For Loop:

  • for(i = 1; i <= 20; i++): A loop that starts with i = 1 and runs until i is 20, incrementing i by 1 on each iteration.

• Power Calculation:

  • m = pow(3, i): The pow function from the math library is used to calculate 3i3^i3i. The result is stored in the variable m.

• Printing the Result:

  • printf("3^%d = %d\n", i, m): The printf function is used to print the result in the format "3^i = m", where i is the current loop counter and m is the calculated power of 3.

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

int main() {
    int i, m;

    // Loop from 1 to 20
    for(i = 1; i <= 20; i++) {
        // Calculate 3 raised to the power of i and cast to int
        m = (int)pow(3, i);
        
        // Print the result
        printf("3^%d = %d\n", i, m);
    }

    return 0; // Return success status
}
