do while Looping On C Programming Language

Syntax for do... while... looping on C programming language is:

do
{
  statement_yang_akan_diulang;
}
while (syarat_perulangan);

Example of do... while... on C programming language:

main()
{
  int a=0;
  do
  {
    printf("Test\n");
    a=a+1;
  }
  while (a<2);
  getch();
}

• First, a valued 0, 0<2, printed word Tes and add valued of a becomes 1 (a=a+1, a=0+1, a=1) saat a<2
• Now, a valued 1, 1<2, printed word Tes and add valued of a becomes 2 (a=a+1, a=1+1, a=2) saat a<2
• Now, a valued 2, 2 is not < 2, not printed word Tes and add valued of a becomes 3 (a=a+1, a=1+1, a=2)

So printed 2 words Test

If looping condition is changed from a<2 becomes a<=2, so that program syntax becomes:

main()
{
  int a=0;
  do
  {
    printf("Test\n");
    a=a+1;
  }
  while (a<=2);
  getch();
}

• First, a valued 0, 0<=2, printed word Tes and add valued of a becomes 1 (a=a+1, a=0+1, a=1) saat a<=2
• Now, a valued 1, 1<=2, printed word Tes and add valued of a becomes 2 (a=a+1, a=1+1, a=2) saat a<=2
• Now, a valued 2, 2<=2, printed word Tes and add valued of a becomes 3 (a=a+1, a=2+1, a=3) saat a<=2
• Now, a valued 3, 2 is not < 2, not printed word Tes and add valued of a becomes 4 (a=a+1, a=3+1, a=4)

So printed 3 words Test

Can be used looping conditional large than (>):

main()
{
  int a=1000;
  do
  {
    printf("Tes\n");
    a=a-1;
  }
  while (a>=998);
  getch();
}

Thank you... : )
