Looping

C# provides several kinds of looping.

Do Loop
The formats and examples are 
  • do {
   statement(s);
} while ( condition );
    _____________________An example_____________________ 
    do {
   num.Text = counter;
   counter  = counter + 1;
} while ( counter <= 1000 );
  • while ( condition ) {
   statement(s);
}
    _____________________An example_____________________ 
    while ( counter > 1000 ) {
   num.Text = counter;
   counter  = counter + 1;
}
For Loop
The format and an example are 
 for ( init; condition; increment ) {
    statement(s);
 }
  ________________________An example________________________ 
 for ( counter = 1; counter <= 1000; counter += 1 ) {
    acc += counter;
 }
Nested Loops
The nested for loop format is 
 for ( init; condition; increment ) {
    for ( init; condition; increment ) {
       statement(s);
    }
    statement(s);
 }
 The nested while loop format is 
 while ( condition ) {
    while ( condition ) {
       statement(s);
    }
    statement(s);
 }
 The nested do ... while loop format is 
 do {
    statement(s);
    do {
       statement(s);
    }
    while( condition );
 }
 while( condition );
