In the C Programming Language, the malloc function allocates a block of memory for an array, but it does not clear the block. To allocate and clear the block, use the calloc function.SyntaxThe syntax for the ma
The syntax of malloc() is: malloc(size_t size); Here, size is the size of the memory (in bytes) that we want to allocate. malloc() Parameters The malloc() function takes the following parameter: size - an unsigned integral value (casted to size_t) which represents the memory block ...
Themalloc()function is a standard library function that allocates a specified amount of memory and returns a pointer to the beginning of this memory block. The syntax formalloc()is as follows: void*malloc(size_tsize); Here,sizerepresents the number of bytes to allocate. The function returns...
