Random number generator: 32-bit and 64-bit random number generator

random.h

It is a header file containing random number generator.

• The random32() generates 32-bit random number
• The random64() generates 64-bit random number
• The random number generator is a basic random number generator using CPU Clock cycle

Note: It does not work on windows

random.c

It includes random.h file and generates 10 random numbers for 32-bit and 64-bit each.

Compilation:

$gcc random.c

Running the code:

$./a.out

swap.c

Swap two varaibles using four methods-

• Swap two varaibles using temporary variable
• Swap two varaibles using multiplication (∗) and division (/) operators
• Swap two varaibles using addition (+) and substraction (-) operators
• Swap two varaibles using XOR operator (^)
