Q4) What is the output of the given below program?

#include<stdio.h>
int main()
{
   for (int i=0; i<5; i++)
   {
      if (i > 2)
         break;
      printf("Know Program \n");
   }
}

a) Know Program is printed 2 times.
b) Know Program is printed 3 times.
c) Know Program is printed 5 times.
d) Know Program is printed infinite times.
e) Compiled Successfully, No Output

View Answer

Answer:- b) Know Program is printed 3 times.

The if-block is executed when i = 3. And the printf() statement will be executed when i = 0, 1, and 2. Therefore “Know Program” will be displayed three times. The printf() statement is not part of the if-block.

Q5) What is the output of the given below program?

#include<stdio.h>
int main()
{
   for (int i=0; i<5; i++)
   {
      if (i > 0)
         break;
      printf("Know Program \n");
   }
}

a) Know Program is printed 1 time.
b) Know Program is printed 5 times.
c) Compiled Successfully, No Output
d) Compile-time error

View Answer

Answer:- a) Know Program is printed 1 time.

The if-block is executed when i = 1, and the printf() statement is executed when i = 0. Therefore the printf() executes only 1 time.

Q6) Find the output of the given program?

#include<stdio.h>
int main()
{
   for (int i=0; i<5; i++)
   {
      if (i > 0)
         break;
         break;
      printf("Know Program \n");
   }
}

a) Know Program is printed 1 time.
b) Know Program is printed 5 times.
c) Compiled Successfully, No Output
d) Compile-time error

View Answer

Answer:- c) Compiled Successfully, No Output

There are two “break” statements. The 1st “break” is part of the if-block and it will execute only when (i > 0), but the 2nd “break” statement is not part of the if-block, it is a valid statement inside for loop and it can execute on any iteration. When i = 0, then if-condition becomes false and if-block won’t be executed. After that “break” (2nd break) is there which will be executed and control came out of the loop. The printf() statement never got a chance to execute.

Q7) What is the output of the given below program?

#include<stdio.h>
int main()
{
   for (int i=1; i<3; i++)
   {
      for (int j=1; j<3; j++)
      {
         if (i > 5)
         break;
      }
      printf("Know Program \n");
   }
}

a) Know Program is printed 2 times.
b) Know Program is printed 3 times.
c) Know Program is printed 5 times.
d) Know Program is printed infinite times.
e) Compiled Successfully, No Output

Answer:- a) Know Program is printed 2 times.

The printf() statement is part of the outer for loop, but not the part of the inner for loop. Therefore execution of printf() completely depends upon the outer for loop. The outer for loop is executed 2 times therefore “Know Program” will be printed 2 times.

Q8) Find the output of the given program?

#include<stdio.h>
int main()
{
   int x=0;
   for (int i=1; i<3; i++)
   {
      x++;
      if (i == 2)
         break;
      printf("Know Program \n");
   }
}

a) Know Program is printed 3 times.
b) Know Program is printed 2 times.
c) Know Program is printed 1 time.
e) Compile-time error

View Answer

Answer:- c) Know Program is printed 1 time.

The if-block will be executed when i == 2. And printf() statement will be executed when i = 1. Therefore the “Know Program” will be displayed only 1 time.

Q9) Find the output of the given program?

#include<stdio.h>
int main()
{
   int i=0;
   while (i<5)
   {
      if (i == 1)
         break;
      i++;
      if (i == 5)
         continue;
      printf("Know Program \n");
   }
}

a) Know Program is printed 1 time.
b) Know Program is printed 4 times.
c) Know Program is printed 5 times.
d) Compiled Successfully, No Output
e) Compile-time error

Answer:- a) Know Program is printed 1 time.

On each iteration, the “i” value is incremented by 1. The “break” statement is executed when i == 1, and the “continue” statement will be executed when i == 5. When i = 0, then both if-condition becomes false and printf() statement got chance to execute. On the next iteration, i = 1, and the first if-condition becomes true therefore “break” statement is executed and control came out of the loop.
