# Find power of any number

## Program to find power of any number

For calculating the power of any number user have four possibilities to input values.

• Value of power is +ve
• Value of Power is -ve
• Value of Base is +ve
• Value of Base is -ve
• Value of power is 0

### Find power of any number

This code only work for when we input +ve power, +ve base value, -ve base value. But it's not work when we enter -ve power value.

## program power of a number

```#include<stdio.h>
#include<conio.h>

void main()
{
int b,p,i,pow=1;
clrscr();
printf("Enter base and power: ");
scanf("%d%d",&b,&p);
for(i=p;i>0;i--)
{
pow=pow*b;
}
printf("power is: %d",pow);

getch();
}
```

## Output

```Enter base and power: 2  3
Power is : 8
```

### Find power of any number

This code satisfy all above Five conditions.

## Program to find power of any number

```#include<stdio.h>
#include<conio.h>

void main()
{
float b,p,i,pow=1;
clrscr();
printf("Enter base and power: ");
scanf("%f%f",&b,&p);
if(p>0)
{
for(i=p;i>0;i--)
{
pow=pow*b;
}
}
else if(p<0)
{
p=p * -1;
for(i=p;i>0;i--)
{
pow=pow*b;
}
pow=1/pow;
}
else if(p==0)
{
pow=1;
}
printf("power is: %f",pow);

getch();
}
```

## Output

```Enter base and power: 2  -2
Power is: 0.25
```

## Program to find power of any number

```#include<stdio.h>
#include<conio.h>

void main()
{
int pow(int,int);
int a,b,r;
clrscr();
printf("Enter base and power  ");
scanf("%d%d",&a,&b);
r=pow(a,b);
printf("power is: %d ",r);
getch();
}
int pow(int x,int y)
{
if(y==0)
return(1);
else
{
return(x*pow(x,y-1));
}
}
```

## Output

```Enter base and power: 3  3
Power is: 27
```
