Write a C program to convert Little to Big endian integer

What is Endianess ?

Little and Big Endian are the ways of storing multi-byte data likes int, float, double etc.

Little Endian

In little endian machines, last byte of binary representation of the multi-byte data is stored first.

Big Endian

In big endian machines, first byte of binary representation of the multibyte data is stored first.

 

 

Code to convert Little endian integer to Big endian 

#include <stdio.h>

unsigned int LitToBigEndian(unsigned int x);

int main( )
{
	int Little_Endian = 0xAABBCCDD ;
	
	printf("\n Little_Endian = 0x%X\n",Little_Endian);
	
	printf("\n Big_Endian    = 0x%X\n",LitToBigEndian(Little_Endian));

}

unsigned int LitToBigEndian(unsigned int x)
{
	return (((x>>24) & 0x000000ff) | ((x>>8) & 0x0000ff00) | ((x<<8) & 0x00ff0000) | ((x<<24) & 0xff000000));
}
