(a)
The following program will determine the value of int(a) where value of a=10.6.
(a)
Explanation of Solution
Program
//included header file
#include <iostream>
//included namespace
usingnamespacestd;
//main function
intmain()
{
//declare variable a with value 10.6
floata=10.6;
//determine and print the value of int(a)
cout<<int(a);
//exiting from program
return0;
}
Explanation:
In the above code, the value of a is 10.6, which is floating-point type value. The int(a) will typecast the value of a to integer type so that it will print only integer part only.
Sample Output:
(b)
The following program will determine the value of int(b) where the value of b=13.9.
(b)
Explanation of Solution
Program
//included header file
#include <iostream>
//included namespace
usingnamespacestd;
//main function
intmain()
{
//declare variable b with value 13.9
floatb=13.9;
//determine and print the value of int(b)
cout<<int(b);
//exiting from program
return0;
}
Explanation:
In the above code, the value of b is 13.9, which is floating-point type value. The int(b) will typecast the value of a to integer type so that it will print only integer part only.
Sample Output:
(c)
The following program will determine the value of int(c) where the value of c=-3.42.
(c)
Explanation of Solution
Program
//included header file
#include <iostream>
//included namespace
usingnamespacestd;
//main function
intmain()
{
//declare variable c with value -3.42
floatc=-3.42;
//determine and print the value of int(c)
cout<<int(c);
//exiting from program
return0;
}
Explanation:
In the above code, the value of c is -3.42, which is floating-point type value. The int(c) will typecast the value of a to integer type so that it will print only integer part only.

(d)
The following program will determine the value of int(a+b) where the value of a=10.6 and b=13.9.
(d)
Explanation of Solution
Program
//included header file
#include <iostream>
//included namespace
usingnamespacestd;
//main function
intmain()
{
//declare variable a with value 10.6 and bwith value 13.9
float a=10.6, b=13.9;
//determine and print the value of int(a+b)
cout<<int(a+b);
//exiting from program
return0;
}
Explanation:
In the above code, the value of a is 10.6 and b is 13.9, which is floating-point type value. The int(a+b) will first add the value a and b then typecast the value of its result to an integer type and then print the value using cout statement.

//determine and print the value of int(a)+b+c
cout<<int(a)+b+c;
//exiting from program
return0;
}
Explanation:
In the above code, the value of a is 10.6, b is 13.9, and c is -3.42, which is floating-point type value. The int(a)+b+c will typecast the value of a to an integer type and then add and print the integer value of a, b and c.

//determine and print the value of int(a+b)+c
cout<<int(a+b)+c;
//exiting from program
return0;
}
Explanation:
In the above code, the value of a is 10.6, b is 13.9, and c is -3.42, which is floating-point type value. The int(a+b) will first add the value a and b then typecast the value of its result to an integer type and then add the value of c to it.
Sample Output:

cout<<abs(a)+abs(b) ;
//exiting from program
return0;
}
Explanation:
In the above code, the value of a is 10.6and b is 13.9, which is floating-point type value. The abs(a) and abs(b)function are used to get the absolute value of a and b then add this absolute value with each other and print the value using cout statement.
