If a=50 and b=4 then determine the results of the following:

Question

1. a+=b
2.a%=b
3.a-=b.
4.a/=b
5.a*=b
6.cout<<100/9
7.float pi =22/7; cout <<pi;

Answer 1

If this is some sort of challenge or quiz then the Q&A section is an inappropriate place for this kind of thing and you should try making a quiz using the quiz factory feature. If it's a genuine question (unlikely) then testing the code using the Sololearn online compiler would be faster than waiting for a response...

Answer 2

although being relevant it seems plausible that this is your homework.
go through the lessons about operators to understand how they work, or write the assignment as a code to output the results of such calculations.
