Question
I wrote a program in which I found the area of cylinder using a functionarea
with a return-type and without parameters. answer
was returned to main
function. However, I am getting different output in main
and a different output in area
. The decimal places seem to be replaced by 0 in the main
function. Why is it so?

Your function returns an int
which truncates any real part of the value.
float area()
Your variable answer
is float in area function but return type of area function is int
. so it typed cased during return, in main
int area(){
^ should be float
float answer;
// print float
return answer;
}
int main(){
answer = area(); // answer gets integral part
// print int part
}
