Calloc Function : Dynamic memory allocation

Calloc Function : Dynamic memory allocation

ptr = (data_type *)calloc(No_of_elements ,sizeof(data_type));

ptr = (int *) calloc(10,sizeof(int));

• calloc :

• Header File : stdlib.h
• Allocate 20 bytes of memory
• Sizeof Returns the Size of Parameter specified 
• 10 means allocate space at run time for 10 elements 
• (int *)  means Typecasting i.e Address of Block of memory is casted to address of Pointer
• On Success : 20 bytes will be allocated
• On Fail : Returns NULL
• Memory Address is assigned to Pointer ptr 
• Calloc is more efficient than malloc because it allocates memory in 1 clock cycle
• Calloc takes 2 arguments
• Allocates memory Block of n*sizeof(data_type )
• Clears allocated memory with Zero
