Assuming i, j, and k have been declared as type int; a portion of the data used by your program is:
3*dim*dim*sizeof(int) + a little bit of space for malloc() bookkeeping {for the malloc()'ed arrays} + 3*sizeof(int *)) {for the pointers} + 3*sizeof(int) {for your loop control variables}.

elf_fsize(3E)															     elf_fsize(3E)

NAME
elf32_fsize, elf64_fsize - return the size of an object file type for elf32 files, return the size of an object file type for elf64 files, respectively. SYNOPSIS
[flag... ] file... [library] ... DESCRIPTION
gives the size in bytes of the 32-bit file representation of count data objects with the given type. The library uses version ver to cal- culate the size (see elf(3E) and elf_version(3E)). Constant values are available for the sizes of fundamental types. Elf_Type File Size Memory Size ------------------------------------------------------ ELF_T_ADDR ELF32_FSZ_ADDR sizeof(Elf32_Addr) ELF_T_BYTE 1 sizeof(unsigned char) ELF_T_HALF ELF32_FSZ_HALF sizeof(Elf32_Half) ELT_T_OFF ELF32_FSZ_OFF sizeof(Elf32_Off) ELF_T_SWORD ELF32_FSZ_SWORD sizeof(Elf32_Sword) ELF_T_WORD ELF32_FSZ_WORD sizeof(Elf32_Word) returns zero if the value of type or ver is unknown. See elf_xlate(3E) for a list of the type values. gives the size in bytes of the 64-bit file representation of count data objects with the given type.
