2.sqrt(x+y) pow(x,y+7) sqrt(area+fudge)
sqrt(time+tide)/nobody (-b+sqrt(pow(b,2)-4*a*c))/(2*a)
abs(x-y)
3.
#include<iostream>
#include<cmath> using namespace std;
int main()
{
for(int i=1,i<=10,i++)
{
root=sqrt(i);
cout<<"the square root for "<<i<<"is "<<root<<endl;
}
return 0;
}
4.to show the case why you wanted to end the program.
5. rand()%10
6.
#include<iostream> #include<cstdlib> using namespace std;
int main()
{
int s;
cout<<"Enter a whole number: ";
cin>>s;
srand(s);
for(int i=0,i<10,i++)
{
random=rand()/static_cast<double>(1.0);
cout<<random;
}
return 0;
}
