How to write power in c language

C library function pow() Learn C programming language with examples using this C standard library covering all the builtin functions. All the C functions, constants and header files have been explained in detail using very easy to understand examples. Write a C program to find power of a number using loop. Logic to find power of a number without using pow() function in C programming.

Learn C programming, Data Structures tutorials, exercises, examples, programs, hacks, tips and tricks online. EDIT: BTW, for the special case of positive integer powers of 2, you can use bit shifting: (1 x) will equal 2 to the power x. There are some potential gotchas with this, but generally it would be correct. Write a C program to input two numbers from user and find power using pow() function.

How to find power of a number in C programming using pow() function. Learn C programming, Data Structures tutorials, exercises, Actually in C, you don't have an power operator.

You will need to manually run a loop to get the result. Even the exp function just operates in that way only. But if you need to use that function, include the following header. Jul 07, 2013 If your design produces the correct answer, then the only thing it may need is just efficiency.

Here is mine: C Programming Operators C Programming while and dowhile Loop The program below takes two integers from the user (a base number In the C Programming Language, the pow function returns x raised to the power of y. Output: 0. Write an iterative O(Log y) function for pow(x, y) Modular Exponentiation (Power in Modular Arithmetic) If you like GeeksforGeeks and would like to contribute, you can also write an article using or mail your article to See your article appearing on the (Exponential) In the C Programming Language, the exp function returns e raised to the power of x.

Syntax. The syntax for the exp function in the C Language is: The exp function returns the result of e raised to the power of x. Required Header. In the C Language, the required header for the exp function is: # include Applies To. Others have already recommended using the pow function from math. h because is not the correct operator for performing power of. Alternatively you can also write your own power function just for fun. Left shift is limited to the word size of your CPU, either 32 or 64 bits, which limits the maximum exponent which you can safely use, before
