Answer:https://ide.codingblocks.com/#/s/27001

what is wrong in this code

#2

Your logic is slightly wrong.
You need to take input of the numbers n1 and n2 only if the user inputs some valid operator like,
+, -, *, /, %.
You are taking input of numbers when user enters X or x also. This is wrong. Try rectifying it.

Modifying that way also doesn’t work https://ide.codingblocks.com/#/s/27335

Can someone comment where my mistake is ?

i removed the last two lines, as i dnt know what they were doing and it worked. take n1 and n2 long long as range of number is 10^6 i guess and multiplying 1000000*1000000=10^12 which exceeds integer range.
