0x80 bytes for heap. A bit few. When you use sprintf increase that to 0x0200 (bytes) Bob

Here we are lucky because the number of columns of each row is equal to their row_index+1. For example, the 0th row has 1 column, 1st row has 2 columns..etc. So we are able to use for loop to call the malloc function. C malloc () The name "malloc" stands for memory allocation. The malloc () function reserves a block of memory of the specified number of bytes. And, it returns a pointer of void which can be casted into pointers of any form. The malloc () function stands for memory allocation.

A single call to malloc allocates a contiguous chunk of heap space of the passed size.

May 31, 2012 Please note the way in which we allocate memory for data on CPU using C's malloc (line 10) and GPU using CUDA's cudaMalloc (line 16),

int matrix[50][100]; // declared a static 2D array of 50 rows, 100 cols To dynamically allocate space, use calls to malloc passing in the total number of bytes to allocate (always use the sizeof to get the size of a specific type). A single call to malloc allocates a contiguous chunk of heap space of the passed size.
