How does clock () work in C?

clock() function in C/C++ The clock() function returns the approximate processor time that is consumed by the program. The clock() time depends upon how the operating system allocate resources to the process that’s why clock() time may be slower or faster than the actual clock. Syntax: clock_t clock( void );
