Go through c lessons for basic syntax

Float accepts decimal values..so I changed it to int.

Answer 2

printf("%d",a*b) for integer value output by compiler by computing a*b here * is different from × which is simple calculation.

Both input value should be in one datatype (like in int otherwise double)
int a;
int b;
Or double a ;
double b;
It's due to their different bytes stored by int , double and other datatypes
So i think you should learn from basics with every modules completing do coding you can easily grasp all this language as least day with a good knowledge.
