سنشرح اليوم الدالة التكرارية

الدالة while & do while 

الهيكل العام لدالة While 

الهيكل العام لدالة  do while 

CODE 1 : 

  


lesson : While Loop & Do while loop


while(condition)
{
   statement(s);
}

while (condition1)
{
 while (condition2)
 {
  statement(s);
 }
}

do
{
   statement(s);

}

while( condition );

CODE 2 : 

  


#include "stdio.h"
#include "stdlib.h"
 main ()

{

   int a = 10;

   /* while loop execution */

   while(2)
   {
      printf("value of a: %d\n", a);
      a++;
   }

system("pause");

}

CODE 3 : 

  

#include 

 main ()
{
   /* local variable definition */
   int a = 10;

   /* do loop execution */
   do
   {
       printf("value of a: %d\n", a);
       a = a + 1;
   }

   while(3 );


}

Calculator  : 

  

#include "stdio.h"

 main ()
{
int option = -1;// we add a value negative to option because we dont want any random value added by compilator
float num1, num2;

printf("\n\n:::::::::::: Calculator :::::::::::: \n\n");
do
{
 printf("\nEnter two numbers : ");
 scanf("%f %f",&num1,&num2);
 printf("\nSelect 1-5 for any operation\n");
 printf("\n1.Addition\n");
 printf("\n2.Subtraction\n");
 printf("\n3.Multiplication\n");
 printf("\n4.Division\n");
 printf("\n5.Exit Program\n");
 printf("\n Your choice  : ");
 scanf("%d", &option);
 printf("\n");

 switch(option)
 {
  case 1:
   printf("\nSummation result is =%.2f\n",num1+num2);
   break;
  case 2:
   printf("\nSubtraction result is =%.2f\n",num1-num2);
   break;
  case 3:
   printf("\nMultiplication result is =%.2f\n",num1*num2);
   break;
  case 4:
   printf("\nDivision result is =%.2f\n",num1/num2);
   break;
  case 5:
   printf("\nTerminating...\n");
   break;
  default:
   printf("\nInvalid operator\n");
   break;
 }
}
while(option != 5);

}
