(4+5)
b) A ‘C’ program contains the following statements:
#include <stdio.h>
int I;
long ix;
unsigned u;
float x;
double dx;
Write an appropriate printf function to write out the values of I, ix, u, x and dx, assuming that each integer quantity will have a minimum filed width of five characters, the long integer will have a minimum filed width of 12 characters, and the floating point quantity will be atleast 10 characters with a maximum of five decimal places.
Q-2 Answer any two: (8)
a) Given a list of marks ranging from 0 to 100, write a C program to compute and print the number of
Students.
i) Who have obtained more than 80 marks.
ii) Who have obtained more than 60 marks.
iii) Who have obtained more than 40 marks.
iv) Who have obtained 40 or less marks
v) Who have obtained marks in the range 81 to 100
vi) Who have obtained marks in the range 61 to 80
vii) Who have obtained marks in the range 0 to 40.
The program should use minimum number of If statements.
b) Write a ’C’ program to generate first N prime numbers.
c) Write a ‘C’ program to sort a list of characters.

mechanism. (3 + 4+1)
b) A ‘C’ program contains the following declaration:
Static int x[8] = {10, 20, 30, 40, 50, 60, 70, 80};
i) what is the meaning of x?
ii) what is the meaning of (x+2)?
iii) What is the value of (*x+2)?
iv) What is the value of *(x+2)?
