# Power of Number in C

Power of Number in C. The power of a number determines how many times it should be multiplied. The product of multiplying a number by itself is called power. What number is being multiplied is indicated by the base number. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

`#include <stdio.h>int main(){int base, exp;long double value = 1.0;printf("Enter a base number");scanf("%d", &base);printf("Enter an exponent");scanf("%d", &exp);while (exp != 0){value *= base;--exp;}printf("Answer = %.0Lf", value);return 0;}`

Output:

Enter a base number4
Enter an exponent5
Solution is 1024

## Power of Number in C to Calculate Decimal Number

A number base is the amount of digits or combinations of digits used to represent numbers in a counting system. Any whole number greater than 0 can be used as a basis. The decimal system, sometimes known as base 10, is the most widely used number system.

## What is Exponent Number in C Program

An exponent is a number or letter that is written above and to the right of the base in a mathematical statement. Power of Number in C this program will produce the result for exponent value in c program.

## Predecrement Operator in C Program

Before utilising a variable in an expression, a pre-decrement operator is used to decrement its value. The value of the variable is first decremented and then utilised in an expression with the pre-decrement operator.

## What is Format Specifier in C

During input and output, the format specifier is utilised. It’s a technique to notify the compiler what kind of data is in a variable when using scanf() or printf() to take input (). Percentages such as c, d, and f are some instances.

Long integer values are represented using the percent ld format specifier. For printing the lengthy integer value contained in the variable, the printf() function is used.
