C# - Continue Statement


Advertisements

Previous Page Next Page

The continue statement in C# let the program skip a block of codes for current iteration in a loop. Whenever continue statement condition is fulfilled, it brings the program to the start of loop. If the continue statement is used in a nested loop (loop inside loop), it will skip innermost loop's code block, whenever condition is fulfilled.

Continue statement with While loop

using System;

namespace MyApplication { 
  class MyProgram {
    static void Main(string[] args) {
      int i = 6;
      int j = 0;
      while (j < i){
          j++;
          if(j == 4){
             Console.WriteLine("this iteration is skipped."); 
             continue;
          }
          Console.WriteLine(j); 
      }
    }
  }
}

Output

1
2
3
this iteration is skipped.
5
6

Continue statement with For loop:

using System;

namespace MyApplication { 
  class MyProgram {
    static void Main(string[] args) {
      for (int i = 1; i <= 6; i++){
          if(i == 4 ){
             Console.WriteLine("this iteration is skipped."); 
             continue;
          }
          Console.WriteLine(i); 
      }      
    }
  }
}

Output

1
2
3
this iteration is skipped.
5
6

Continue statement with Nested loop:

The Continue statement skip the inner loop's block of codes whenever condition is fulfilled. In below mentioned example, program skips the inner loop only when j = 100.

//Nested loop without continue statement
using System;

namespace MyApplication { 
  class MyProgram {
    static void Main(string[] args) {
      for (int i = 1; i <= 3; i++){
        for (int j = 10; j <= 1000; j = j * 10){
          Console.WriteLine(i*j); 
        }
      }      
    }
  }
}

//Nested loop with continue statement
using System;

namespace MyApplication { 
  class MyProgram {
    static void Main(string[] args) {
      for (int i = 1; i <= 3; i++){
        for (int j = 10; j <= 1000; j = j * 10){
          if(j == 100 ){
             continue;
          }
          Console.WriteLine(i*j); 
        }
      }      
    }
  }
}

Output

# output of nested loop without continue statement
10
100
1000
20
200
2000
30
300
3000

# output of nested loop with continue statement
10
1000
20
2000
30
3000
