In this tutorial, we are going to write a **C Program to evaluate the equation y=xn** when n is a non-negative integer in C Programming with practical program code and step-by-step full complete explanation.

## C Program to evaluate the equation y=xn

#include<stdio.h> #include<conio.h> void main() { int count, n; float x,y; printf("Enter the values of x and n: "); scanf("%f%d",&x,&n); y=1.0; count=1; while(count<=n) { y=y*x; count++; } printf("x=%f n=%d x to power n=%f",x,n,y); }

### Output

Enter the values of x and n: 2.5 4 X=x.500000 n=4 x to power n=39.062500
