How can I make an array with variable size in the C language?
Can you explain more about these functions?
Sure! 'malloc' function is used to allocate a block of memory of given size in bytes and it returns a pointer of void type. 'calloc' function is used to allocate a block of memory of given size in bytes and it initializes all the memory locations with zero. 'realloc' function is used to resize the previously allocated memory block.
