The way we have constructors for user defined data types, we also have constructors for built in data types like chat, int, float and so on. Here is a program that demonstrates this:
#include int main(){ int i1=int(); int i2=int(5); char c1=char(); char c2=char('F'); float f1=float(); float f2=float(3.29); cout<<"int()->"<"<"<"<"<"<0int(5)->5char()->char('F')->Ffloat()->0float(3.29)->3.29
