Problem : Check whether given number is power of 2 using bitwise operators in C Algorithm : Let us see the binary representation of numbers which are power of 2: As we can see in above example,any number which is power of 2 has only 1 bit set. Now let us subtract 1 from above … Read more
One of the easiest ways to fine the length of the string in C is by using built-in function strlen. Using below code, we can find the length of the string without using any built-in functions. Output:
Problem : Write a optimized code to check whether the system is Big or Little Endian using C Understanding: Endianness of the system describes how the multibyte data are stored(int, float..etc). Let us take example of Big Endian vs Little Endian representation of number 0x11223344 Using above idea, we can use below program to check … Read more
Problem : Write a best approach to count the number of bits set in given integer number using C. Understanding : All the numbers can be represented in Binary Format. For example Number 5 can be represented as 0101. Our program should take number 5 as number and count the number of bits set and … Read more
One of the easiest ways to find whether modern processor is 32-Bit or 64-Bit is by understanding the size of generic pointer(void*). Below is the C code which prints the 32/64 Bit:
