Before using this you should have copied the code by selecting the entire code and pressing cntrl-c. (Line numbers will not come in the copied code). After that open any of the service and press cntrl-v to paste in the given code area. Needs a bit of tweaking as per the link.

-OR-
Enter an integer numbers :24
Square of 24 = 576

Solved Problem Understanding

int n; cout<<“Enter an integer numbers :”; cin>>n;
Number is collected from the user in the integer variable n.

if(n%2==0) cout<<“Square of “<<n<<” = “<<n*n<<endl; n%2==0 tests divisibility by using modulus operator % and checking the remainder. If divisible means number is even so squaring is done by n*n.

else cout<<“Cube of “<<n<<” = “<<n*n*n<<endl;
If it is not even then as per need of the program we shall make its cube using n*n*n.

Code Notes

This program can be given for any power. So we can make a generic call using the pow(base,power) function by using the math.h library
