linux - Clean console on assembly -


is there similar system("cls"); exists on c assembly?

i'm using nasm compile , i'm working on x86 linux.

update 1: here's modified code integrate sugestion:

section .data  %define sc_write        4   ; eax = write(ebx, ecx, edx) %define esc         033q   max_palavra equ 40  (...)  num1        dd  0 num2        dd  0 result      dd  0 tamstr      dd  0  section .bss strnum      resb    max_palavra opc     resb    2  section .text  global _start     refresh:         mov eax, esc | ('[' << 8) | (bottomrow << 16)         stosd         mov eax, ';0h' | (si << 24)         stosd         mov edx, edi         mov edi, outbuf         mov ecx, edi         sub edx, ecx         xor ebx, ebx         lea eax, [byte ebx + sc_write]         inc ebx         int 0x80  _start:  mov eax, ds mov es, eax

cheers

to imitate terminals clear command have in .data section:

clearterm: db   27,"[h",27,"[2j"    ; <esc> [h <esc> [2j clearlen   equ  $-clearterm         ; length of term clear string

then whenever want clear terminal do:

mov eax, 4                          ; specify sys_write call mov ebx, 1                          ; specify file descriptor 1: stdout mov ecx, clearterm                  ; pass offset of terminal control string mov edx, clearlen                   ; pass length of terminal control string int 80h

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
