Program x to power y in C Language

7:36 AMFriday, January 8, 2016

Introduction 

The meaning of x to the power of y is , a variable x is multiply for y time. Lets take a simple example a variable x is hold 2 and y hold 5. Now the answer is 2 multiply for 5 times such as..
z=2*2*2*2*2;
z=32

Method-1: 

Design a Algorithm in c

Step-1 : Take two value in variable x and y by user input.
Step-2 :  Use pow function in  "C" , which is available in math.h header file.
Step-3 :  Take another variable Z for holding answer of the x to the power of y.
Step-4 : Print z 
Step-5 : End of the program.

Program :

#include<conio.h>
#include<stdio.h>
#include<math.h>
void main()
{
int x,y,z;
printf("enter X value");
scanf("%d",&x);
printf("Enter Y value");
scanf("%d",&y);
z=pow(x,y);
printf("output of the x power y is%d",z);
getch();
}

Output
Program x to power y in C


Method-2 : Using recursion

Algorithm of the program

Step-1: Step-1 : Take two value in variable x and y by user input.
Step-2: Create a function  and pass values of x and y  to the function.
Step-3 : Call same function for y times 
Step-4 : Return function 

Program

#include<conio.h>
#include<stdio.h>
#include<math.h>
void main()
{
int x,y,z;
clrscr();
printf("enter X value");
scanf("%d",&x);
printf("Enter Y value");
scanf("%d",&y);
z=fun(x,y);
printf("output of the x power y is%d",z);
getch();
}
int fun(int a,int b)
{
if(b>=1)
{
return a*fun(a,--b);
}
else
return 1;
}




Output
Program x to power y in C

Method -3:Using third variable

Algorithm:
Step-1: Take two value in variable x and y by user input.
Step-2: Run for loop for y times.
Step-3 : Take third variable z with 1 value
Step-4 : Multiply x with z for y times in for loop
Step-5 : Take output value in z variable
Step-6 :  End of the program

Program


#include<conio.h>
#include<stdio.h>
#include<math.h>
void main()
{
int x,y,i,z=1;
clrscr();
printf("enter X value");
scanf("%d",&x);
printf("Enter Y value");
scanf("%d",&y);
for(i=0;i<y;i++)
{
z=x*z;
}
printf("output of the x power y is%d",z);
getch();
}

Output

Program x to power y in C
