Your code seem to be correct i guess their is constraints that yiur input number should be between 0.00 to 500.00 so after input u need to check thats number is between given constraints or not Like this If( numb1>=0&&numb1<=500)

You need to use modf() function from <math.h>. The function's purpose is to break a floating point value into integral and fractional parts. http://www.cplusplus.com/reference/cmath/modf/ Once you extracted the integral parts of the two numbers, you can then convert them into int values before summing up.

Simple. You change the numbers to integers before adding. Problem solved https://code.sololearn.com/cS1sQ3pd7TtA/?ref=app

And there is another reason why I took int because it's given in mandatory test case 2 that it should be taken int sum;

It works fine, you just have an extra pound on the first line. Delete one

Ahh, that because the sum variable is an integer. An integer can't be a float unless cast, so switch the declaration from an int to a float shravya https://code.sololearn.com/cNjIWXyp1NEO/?ref=app
