Question

Submit a menu based C++ program that can compute at least Ten Mathematical functions from <math.h> or <cmath.h> library.  

The input is provided by the user.

Answer 1

code:

#include <bits/stdc++.h>

#include <math.h>
using namespace std;
void choice()
{
cout << "Press 1 for calculating sine value of a Number\n";
cout << "Press 2 for calculating cos value of a Number\n";
cout << "Press 3 for calculating tangent value of a Number\n";
cout << "Press 4 for calculating square value of a Number\n";
cout << "Press 5 for calculating absolute value of a Number\n";
cout << "Press 6 for calculating round value of a Number\n";
cout << "Press 7 for calculating truncated value of a Number\n";
cout << "Press 8 for calculating Floor value of a Number\n";
cout << "Press 9 for calculating ceil value of a Number\n";
cout << "Press 10 for calculating log value of a Number\n";
cout << "Press 11 to exit\n";
}
void operation(int cho,int a)
{
switch(cho){
case 1:
{
cout << "Sine value is " << sin(a) << endl;
break;
}
case 2:
{
cout << "Cosine value is " << cos(a) << endl;
break;
  
}
case 3:
{
cout << "Tangent value is: " << tan(a) << endl;
break;
}
case 4:
{
cout << "Square root is : " << sqrt(a) << endl;
break;
  
}
case 5:
{
cout << "Absolute value is: " << abs(a) << endl;
break;
  
}
case 6:
{
cout << "Round value is : " << round(a) << endl;
break;
}
case 7:
{
cout << "Truncated value is: " << trunc(a) << endl;
break;
}
case 8:
{
cout << "Floor value is : " << floor(a) << endl;
break;
}
case 9:
{
cout << "Ceiling value is: " << ceil(a) << endl;
break;
  
}
case 10:
{
cout << "Log value : " << log(a) << endl;
break;
}
case 11:
{
cout<<"Wrong input";
}
}}
int main()
{
int a;
int cho;
choice();
cout<<"Enter choice :";
cin>>cho;
cout<<"Enter value: ";
cin>>a;
operation(cho,a);
return 0;
}

output:
we can also change the datatype of the number;

thankyou
