Answer 2

Switch statement:  It is one of decision-making control flow statements.

Now, I am gonna illustrate the switch case with and without break statements.

(i)

Switch With break statements: - Default one:

#include<stdio.h>

int main()

{

int a = 2;

switch(a)

{

case 0:

printf("A");

break;

case 1:

printf("B");

break;

case 2:

printf("C");

break;

default:

printf("D");

break;

}

return 0;

}

Output: C

Reason: Here, i have used break statement to break the flow of control of every case block.

-------------------------------------------------------------------------------------------------------------

(ii)

Switch without break statements:

#include<stdio.h>

int main()

{

int a = 2;

switch(a);

{

case 0:

printf("A");

case 1:

printf("B");

case 2:

printf("C");

default:

printf"(D");

}

return 0;

}

Output : CD

Reason: Here, with the absence of break statement, all the statements below the matched case gets executed.

Hope this helps!
