Please help me solve this problem in C++ language.

Recall that if you want to use one predefined function from the C or C++ library, you have to include the header file at the top of your program and learn the signature of the function to know how to call it. 1/2 Given that X X Two functions that can be used to calculate the square root of a number are Function pow and function sqrt that are predefined mathematical functions available in the library cmath with their signatures are: double pow (double base, double exponent) > double result pow (16,0.5): //result4 double sqrt (double x); double result-sqrt(16); // result-4 The following program is an example that uses the predefined functions, pow and sqrt to calculate the square root of a number entered by the user. Save this program as sqrt.cpp to the folder lab5 in your working folder 1. //Calculate the square root of a number using sqrt and pow 2. #include iostream 3. #include math 5. using namespace std; 7. int main () 8. f 9. double x; 10. double result; 12. cout "Enter a (double) value : "; 13, cin x; 14
