QUESTION:
----------------

Area of a triangle is given by the formula
A=sqrt(S(S-a)(S-b)(S-c))
Where a, b and c are sides of the triangle and 2S=a+b+c. Write a program to compute the area of the triangle given the values of a, b and c

CODDING:
---------------




void main()
{
int a,b,c;
float S,Area;
a=b=c=S=0;
clrscr();

a=20;
b=30;
c=40;
S=(a+b+c)/2;
Area=sqrt(S*(S-a)*(S-b)*(S-c));
printf("Area of a triangle is= %f",Area);
getch();
}

OUTPUT:
-------------
Area of a triangle is= 290.473755

QUESTION:
---------------
Given the values of three variables a, b and c, write a program to compute and display the values of x, where
X= a / (b -c)
Execute your program for the following values:
(a) a=250, b==85,c=25

CODDING:
---------------


void main()
{
clrscr();
int a,b,c;
float x;
a=250;
b=85;
c=25;
x=a/(b-c);
printf("x = %f\n",x);
a=300;
b=70;
c=70;
x=a/(b-c);
printf("x = %f\n",x);
getch()

OUTPUT:
-------------
x=4.000000

QUESTION:
-----------
Given two integers 20 and 10, write a program that uses a function add() to add these two numbers and sub() to find the difference of these two numbers and then display the sum and difference in the following form:
20 + 10 = 30
20-10 = 10

CODDING:
---------


void main()
{
clrscr();
int Sum,Diff;
printf("First Number 20\n");
printf("Second Number 10\n");
Sum=20+10;
Diff=20-10;
printf("20 + 10 = %d\n", Sum);
printf("20 -10 = %d", Diff);
getch();
}

OUTPUT:
--------
20 + 10 = 30
20 -10 = 10

QUESTION:
------------
Given the radius of a circle, write a program to compute and display its area.
Use a symbolic constant to define the p value and assume a suitable value for
radius.

CODDING:
----------


PIE 3.14
void main()
{
clrscr();
float Rad,Area;Rad=4;
Area=PIE*Rad*Rad;
printf("Area of a circle is--> %f",Area);
getch();
}

OUTPUT:
-----------
Area of a circle is 50.240002
