Programming task:
#include <stdio.h>
#include <math.h>
int main(){
int number;
double b;
printf("Enter a number: ");
scanf("%d", &number);

printf("%lf", sqrt(number));

b = sqrt(number);


double result = pow(number, b);
printf("\nThe result: %lf ", result);


}

#include <stdio.h>
#include <math.h>

int main() {

int num;
printf("Enter a number: ");
scanf("%d", &num);

double squareRoot = ("%lf", sqrt(num));

double result = pow(num, squareRoot);
printf("%lf", result);

return 0;
}

Q. What is the correct way to include a library file in our program?

1. Math.sqrt()
2. #include <math.h>
3. #include Math.sqrt()
4. math.sqrt()

I recenty found out you guys, this is such a great series, so much information described in detail. You guys deserve more, I shared it to my peers, Keep going

[stealthy_doctor]

Wonderful tutorial and intro to library functions!
the answer i think is B for the correct way to input collection functions and for the code i just did this:
#include <stdio.h>
#include <math.h>

int main() {
// Write C code here
double number;

printf("Enter a Number: ");
scanf("%lf", &number);

double root = sqrt(number);
double result = pow(number, root);

printf("\nThe result is %lf", result);

return 0;
}

Mam, I am beginner in this field, I found your videos very very helpful, great content ❤️

[davidjabulani]

Very easy to understand
thank you programiz

Programming task:
#
#
Int main(){
Int number;
Int b;
Printf("enter a number:");
Scanf("%d", &number);
{
Printf("%lf", sqrt(number));
b=sqrt(number);
double result=pow(number, b);
Printf("\nThe result:%lf", result);
}
return 0;
}

#include <stdio.h>
#include <math.h>

int main() {
int a = 12;
int b = 14;
double reslut = pow( a, b);
printf("Power : %lf", reslut);
return 0:
}

great content, i was struggling with this topic this video saved me thanks.

[jmarkyt]

#include <stdio.h>
#include <stdbool.h>
#include <math.h>

int main(){

double num;

printf("Put a number: ");
scanf("%lf", &num);

double result = sqrt(num);
printf("Square Root is: %.2lf", result);

double power = pow(num, result);
printf("\nThe answer is %.2lf", power);
return 0;
}

OUTPUT:

Put a number: 5
Square Root is: 2.24
The answer is 36.78

Option B : #include <math.h>



#include <stdio.h>
#include <math.h>

int main()
{
while(1)
{
int num;

printf("\nEnter A Number : ");
scanf("%d", &num);

double squareroot = sqrt(num);

printf("%.2lf", pow(num, squareroot));
}

return 0;
}
