It returns a pointer to the allocated memory. If the allocation fails, it returns NULL. The prototype for the standard library function is like this: void *malloc(size_t size );.

The code snippet that shows this is as follows. So I need to use malloc to create my arrays. So I cant use int A [rows] [cols]. Code: /* This program asks the user for 2 matrices called A and B, as integers, and displays their sum, C. The max dimension of each matrix is 100. */ #include // Construct function void construct () { int m, n, i, j; // Variables int first [ 100 ] [ 100 ], I would use calloc instead of malloc since you're anyway clearing the matrix after allocation. void* cmatrix = calloc(1, matsize); //memset((void*) cmatrix, 0, matsize); this is not needed anymore because of 'calloc' Also I do not think there is any point in using char* here because.

printf("Memory allocation failed while allocating for matrix[].\n"); exit(-1); } for(i = 0; i < rows; ++i){ matrix[i] = (int *) malloc(cols * sizeof(int));

If the operation is successful, it returns a pointer to the memory block. If the operation is unsuccessful ( malloc() is unable to find contiguous memory block of required size ), it returns NULL.

About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators The malloc() function stands for memory allocation. It is a function which is used to allocate a block of memory dynamically. It reserves memory space of specified size and returns the null pointer pointing to the memory location.

to refresh your session. A matrix view is a temporary object, stored on the stack, which can be used to operate on a subset of matrix elements. Matrix views can be defined for both constant and non-constant matrices using separate types that preserve constness.
