# C Exercises: Evaluate the equation y=xn when n is a non-negative integer

## C Basic Declarations and Expressions: Exercise-67 with Solution

Write a C program to evaluate the equation y=xn when n is a non-negative integer.

**Sample Solution:**

**C Code:**

```
#include <stdio.h>
int main(){
int count, n;
float x,y;
// Input the values of x and n
printf("Input the values of x and n:\n");
scanf("%f%d", &x,&n);
y=1.0;
count=1;
// Calculate x to the power n
while(count<=n)
{
y=y*x;
count++;
}
// Print the result
printf("x=%f; n=%d; \nx to power n=%f", x, n,y);
return 0;
}
```

Sample Output:

Input the values of x and n: 256 x=256.000000; n=0; x to power n=1.000000

**Flowchart:**

**C programming Code Editor:**

**Previous:**Write a C program that generates 50 random numbers between -0.5 and 0.5 and writes them in a file rand.dat. The first line of ran.dat contains the number of data and the next
50 lines contains the 50 random numbers.

**Next:** Write a C program to print the powers of 2 table for the power 0 to 10, both positive and negative.
