C programming

jumps in loops

In C programming, "Jumps in loops" refer to keywords that alter the normal flow of control within a program. These statements allow you to transfer control from one part of your code to another. There are three primary jump statements in C: break, continue, and goto.

Syntax for break:

break;

Explanation:

break Statement in C:

Purpose: The break statement is used to exit or terminate a loop (such as for, while, or do-while) or a switch statement prematurely.
When encountered inside a loop or switch statement, the break statement immediately exits the loop or switch, transferring control to the statement immediately following the loop or switch.

Sample code:

      #include <stdio.h>
          int main() 
         { 
         int i;
          for (i = 1; i <= 10; ++i) 
         {
          if (i == 5)
          {
          printf("Break at i = 5\n");
          break; // Exit loop when i is 5
          }
          printf("i = %d\n", i);
          }
          printf("Loop ended\n"); 
         return 0;
          }

Output:

      i = 1
      i = 2
      i = 3
      i = 4 
     Break at i = 5
     Loop ended

syntax for continue

continue;

Explaination

Purpose: continue is a control statement used to skip the current iteration of a loop (for, while, do-while) and proceed to the next iteration.
It moves the control to the loop's increment expression (in case of for loops) or condition checking (in case of while or do-while loops).
It doesn’t execute the remaining code within the loop for the current iteration

  #include <stdio.h>
      int main() {
          for (int i = 1; i <= 5; ++i) {
              if (i == 3 || i == 4) {
                  printf("Skipping iteration %d\n", i);
                  continue;
              }
              printf("Executing iteration %d\n", i);
          }
          return 0;
      }

output:

  Executing iteration 1
  Executing iteration 2
  Skipping iteration 3
  Skipping iteration 4
  Executing iteration 5

Q1. The continue statment cannot be used with ________

A. for

B. while

C. do while

D.switch

Q2. In the context of "break" and "continue" statements in C, pick the best statement.

A. "break" and "continue" can be used in "for", "while", "do-while" loop body and "switch" body

B."break" and "continue" can be used in "for", "while" and "do-while" loop body. But only "break" can be used in "switch" body

C."break" and "continue" can be used in "for", "while" and "do-while" loop body. Besides, "continue" and "break" can be used in "switch" and "if-else" body

D. "break" can be used in "for", "while" and "do-while" loop body
