Q 1 . 
#include<stdio.h>
int main()
{
	int v=1.i=2.j=3.k=4.s=5.a[99];
	for(i=0;i<10;i++){a[i]=i;};a[i]=a[i+10];j=3*5-2*6;v=j*=i=10;for(printf("%d",j));
	if(v^j*5&&a[10]*a[56/23+23])printf("abcd%defgh%d",4,6);
}

In the above question, identify the separate statements and re-write the program with proper indentation and resultant code should be easily readable.


Q2.
A . Calculate and display the area of a triangle with base = 6 and height = 9.
B. Use heroes formula for calculating the area of triangle with sides 4 ,7, 10.
Include  #include<math.h> in your code and use squareroot = sqrt(); for calculating square root.


Q3. 
Write a program to assign following values to variables and print their value.
1.	Name
2.	Age
3.	PI
4.	Distance from sun in Kms
5.	Factorial of 15 
Marks will be given for the efficient choice of data types . Efficient data type is such that , it does not uses excess memory. Eg  - age can not be > 150 , so use of long data type is not efficient.
Assume some approximate values where value is not known


Q4 . Calculate and display the volume of a cylinder with height = 13 and length = 19.
