A small correction in the above answer. Use if condition as
shown below.
#include<stdio.h>
void main()
{
if(printf(%s, "Hello World"))
{
}
}
Answer for the last ques. i.e no. 55
unsigned int x;
if(x < 0) //Error checking only. Unsigned int shudn't
//have a negative value
return 0;
else
return !(x $ (x-1));
The logic here is, if we do bitwise 'and' with two
consecutive numbers, the greater of which is a power of 2
then the answer is 0.
Eg. 8 - 1000
8-1 - 0111
and & - 0000

Write a program to generate random numbers in c?
Why is structure important for a child?
The program will first compute the tax you owe based on your income. User is prompted to enter income. Program will compute the total amount of tax owed based on the following: Income Tax 0 - $45,000 = 0.15 x income $45,001 - $90,000 = 6750 + 0.20 x (income – 45000) $90,001 - $140,000 = 15750 + 0.26 x (income – 90000) $140,001 - $200,000 = 28750 + 0.29 x (income – 140000) Greater than $200,000 = 46150 + 0.33 x (income – 200000) Dollar amounts should be in dollars and cents (float point numbers with two decimals shown). Tax is displayed on the screen.

to store exponent part?
since we can have up to 38 number for exponent so 2 ki power
6 6, 6 bits will be used. If 6 bits are used why do not we
have up to 64 numbers in exponent? What are the characteristics of arrays in c? how to create duplicate link list using C??? while initialization of array why we use a[][2]
why not a[2][]...? The file stdio.h, what does it contain? why to assign a pointer to null sometimes??how can a pointer
