Problem with decimal values

Help,I know I am doing something wrong here and the answer is pretty obvious yet I can't figure it out. I think the output should have been a decimal value(upto some decimal point if cpp cant handle irrational values).But the output is integer value much like modulus(%) //code here https://code.sololearn.com/c2Ld7UjF2FfH/?ref=app

(i) Only one of them need to be float. So instead of 22 write 22.0 or float(22). (ii) float pi = int(22) / int(7); => float pi = 3; => cout << pi; // would be 3.

(int) / (int) will result in int. Write (float)22 / 7 then you will see 3.14!

thanks soheil, that answered my query regarding the output of a integer in the cout statement. Modifying that line will now result in a decimal value cout<<22.0/7; output-3.14 //and not cout<<22/7; resulting in a integer (3) //thanks for reminding me that concept but what about this statement float pi; pi=22/7; (i)do I still have to convert 22 to 22.0 and 7 in the similar way? (ii)isn't pi already declared a float type so by my guess(which could be wrong here) it should print out a decimal containing value?

ahh ok! so for float, either values should contain a decimal or float(any integer here) both are valid. That was really helpful thanks and have a great day ahead!
