To calculate y raised to power x

Topics Covered:

1. To read temperature in Fahrenheit and convert it into Celsius
2. To calculate y raised to power x
3. To swap the value of two variables

 

//to read temperature in fahrenheit and convert it into celsius

#include<conio.h>

#include<stdio.h>

int main()

{

float f,c;

printf(“enter the temerature in fahrenheit\n”);

scanf(“%f”,&f);

c=(f-32)*0.5556;

printf(“temperature in celsius=%f”,c);

return 0;

}

 

//to calculate y raised to power x

#include<math.h>

int main()

{

int x,y,p;

printf(“enter the values for base and power”);

scanf(“%d%d”,&x,&y);

p=pow(x,y);

printf(“product=%d”,p);
