What is the difference between 'malloc()' and 'calloc()'?

malloc():

• creates the single block (a block of memory in bytes) of given size by user.
• initializes the reserved memory block to garbage value.
• takes only one argument.

calloc():

• creates multiple blocks of given size.
• initializes the reserved memory block to zero.
• calloc takes two arguments.

int *p;
p=(int*) malloc(sizeof(int)*5);

p=(int*) calloc(5, sizeof(int)*5);
