Example
#include <stdio.h>
int main ()
{
/* local variable definition */
int a = 10;
/* while loop execution */
while( a < 20 )
{
printf("value of a: %d\n", a);
a++;
if( a > 15)
{
/* use the break statement to terminate the loop */
break;
}
}
return 0;
}
int main ()
{
/* local variable definition */
int a = 10;
/* while loop execution */
while( a < 20 )
{
printf("value of a: %d\n", a);
a++;
if( a > 15)
{
/* use the break statement to terminate the loop */
break;
}
}
return 0;
}
When the above code is compiled and executed, it produces the following results:
a 的值： 10 a 的值： 11 a 的值： 12 a 的值： 13 a 的值： 14 a 的值： 15other extensions
