## Description

In this program, we will take two inputs from the usrs, one will be the** base and the another one is exponent.**

For example: 3^{2}

3 is the base number.

2 is the exponent.

power is equal to 3 * 3.

## Write a c program to calculate the power of given number without using the pow() function.

```
#include<stdio.h>
int main(){
int base, exp, pow = 1;
printf("Enter the base number : ");
scanf("%d", &base);
printf("Enter the exponent : ");
scanf("%d", &exp);
for(int i = 1; i <= exp; i++){
pow = pow * base;
}
printf("%d ^ %d is : %d", base, exp, pow);
return 0;
}
```

## Write a c++ program to calculate the power of given number without using the pow() function.

```
#include<iostream>
using namespace std;
int main(){
int base, exp, pow = 1;
cout<<"Enter the base number : ";
cin>>base;
cout<<"Enter the exponent : ";
cin>>exp;
for(int i = 1; i<=exp; i++){
pow = pow * base;
}
cout<<base<<"^"<<exp<<" = "<<pow;
return 0;
}
```

## Algorithm to calculate power given number.

Step 1: START

Step 2: READ base and exp

Step 3: SET pow = 1

Step 4: START for loop, when condition (i<=exp) is true then go to STEP 5.

Step 5: CALCULATE pow = pow * base.

Step 6: EVERY Iteration increment i by 1.

Step 7: PRINT pow

Step 8: EXIT

## Working of calculate of power.

Initial i = 1, i <= 3 condition true then.

pow = 1 * 2 = 2.

pow = 2.

After this increment iteration i by 1.

Now i = 2

pow = 2 * 2 = 4

After this increment iteration i by 1.

Now i = 3

pow 4 * 2 = 8

After this increment iteration i by 1.

Now i = 4.

Loop is Terminate Because the condition is false.

## Calculate Power with pow() function in c programming.

```
#include<stdio.h>
#include<math.h>
int main(){
int base, exp;
printf("Enter the base number : ");
scanf("%d", &base);
printf("Enter the exponent : ");
scanf("%d", &exp);
int power = pow(base, exp);
printf("%d", power);
return 0;
}
```

## Calculate power with pow() function in c++ programming.

```
#include<iostream>
#include<math.h>
using namespace std;
int main(){
int base, exp;
cout<<"Enter the base number : ";
cin>>base;
cout<<"Enter the exponent : ";
cin>>exp;
int power = pow(base, exp);
cout<<power;
return 0;
}
```
