In C language, I need to format a number to 2 digits after the decimal point from user input

For example:

 float x ; 
 printf("Enter number");

Let's suppose the user enters 4.54234635

I need to print and process in the whole program: 4.54

Thanks advance

Answer 1

scanf("%.2f",&x);

And i think that will solve a problem
