Hello,

I solved some exercises on the textbook calledA First Book of ANSI Cby myself and really happy about that. I have a major problem with one exercise. It says i have to use the (int) cast, devise a method to round the values in the variables a and b to the nearest hundredth (penny value) before they are added.

I have no idea what the question means!!! Any advice? I read a different book i brought from Korea to solve it in my own way but I dont know its right or not.

I tried to find solutions for the textbook but cant find it.

Question

My code:Code:`double a, b, c;`

a = 1.674;

b = 1.322;

printf("\n%4.2f",a);

printf("\n%4.2f",b);

printf("\n----");

c = a + b;

printf("\n%4.2f\n",c);

Code:`#include<stdio.h>`

#include <math.h>

int main()

{

double a, b, c;

a = 1.674;

b = 1.322;

double round (double x);

a = round(a*100)/100;

b = round(b*100)/100;

printf("\n%4.2f",a);

printf("\n%4.2f",b);

printf("\n----");

c = a + b;

printf("\n%4.2f\n",c);

return 0;

}
