Thread: what is meant by the term typecast in c programming?

Casting from one type to another.

For example you have a number that is of type float and you wanted to put it into a double

float x=1.24f;
double y = (double)x;

x is then promoted to a type of double.

I little more practical example.

int x = 5/2;
double y = 5/2;
double z = (double)5/2;

x = 2 since it is an integer
y you might think is 2.5 but its 2.0 since 5 and 2 are integers it goes with the rules of integer division first.
z however prompts 5 to a double then divides by 2 giving you the result of 2.5
