Evaluate y=xn

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

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.
